Introduction 1.1 Scope The test methods and results described in this document are intended to provide basic composite properties essential to most methods of analysis and are consistent with MIL-HDBK-17-1F—Composite Materials Handbook for Polymer Matrix Composites. This report contains material property data of common usefulness to wide range of projects. The lamina and laminate material property data have been generated with FAA oversight through FAA Special Project Number SP4652WI-Q and also meet the requirements of NCAMP Standard Operating Procedure NSP 100; the test panels, test specimens, and test setups have been conformed by the FAA and the testing has been witnessed by the FAA. However, the data may not fulfill all the needs of any specific company's programs; specific properties, environments, laminate architecture, and loading situations may require additional testing. The use of NCAMP material and process specifications do not guarantee material or structural performance. Material users should be actively involved in evaluating material performance and quality including, but not limited to, performing regular purchaser quality control tests, performing periodic equivalency/additional testing, participating in material change management activities, conducting statistical process control, and conducting regular supplier audits. The applicability of NCAMP material property data, material allowables, and specifications must be evaluated on case- by-case basis by aircraft companies and certifying agencies. NCAMP assumes no liability whatsoever, expressed or implied, related to the use of the material property data, material allowables, and specifications. This report contains material property data only. Statistical analysis of the data including the calculations of b-basis values is given in a separate report, Hexcel IM7 Unidirectional Prepreg 190 gsm 35% RC Qualification Statistical Analysis Report NCP-RP-2009-028 N/C. The qualification material was procured to NCAMP Material Specification NMS 128/2 Rev - Initial Release dated February 6, 2007. The panels were fabricated by Cessna Aircraft Company, 5800 E Pawnee, Wichita, KS 67218. The qualification test panels were cured in accordance with Baseline Cure Cycle (M) of NCAMP Process Specification NPS 81228 Rev A Initial Release June 7, 2007. The NCAMP Test Plan NTP 1828Q1 Rev B was used for this qualification program. Part fabricators that wish to utilize the material property data, allowables, and specifications may be able to do so by demonstrating the capability to reproduce the original material properties; a process known as equivalency. More information about this equivalency process including the test statistics and its limitations can be found in Section 6 of CAM-RP-2009-015 April 22, 2011 Revision A Page 9 of 238 DOT/FAA/AR-03/19 and Section 8.4.1 of MIL-HDBK-17-1F. The applicability of equivalency process must be evaluated on program-by-program basis by the applicant and certifying agency. The applicant and certifying agency must agree that the equivalency test plan along with the equivalency process described in Section 6 of DOT/FAA/AR-03/19 and Section 8.4.1 of MIL-HDBK-17-1F are adequate for the given program. Aircraft companies should not use the data published in this report without specifying NCAMP Material Specification NMS 128/2. NMS 128/2 have additional requirements that are listed in its prepreg process control document (PCD), fiber specification, fiber PCD, and other raw material specifications and PCDs which impose essential quality controls on the raw materials and raw material manufacturing equipment and processes. Aircraft companies and certifying agencies should assume that the material property data published in this report is not applicable when the material is not procured to NMS 128/2. NMS 128/2 is a free, publicly available, non-proprietary aerospace industry material specification. The data contained in this report is intended for general distribution to the public, either freely or at a price that does not exceed the cost of reproduction (e.g. printing) and distribution (e.g. postage). Data that is subject to export control regulations, if any, will be made available on a case by case basis through written request to NCAMP.

HSP-T2 is similar but not equivalent to ASTM E2092. Table 1-3: Physical Testing Matrix 1.5.5 Environmental Conditioning The following tests were performed by the NIAR Composites Laboratory under the supervision of NCAMP. Test environments are defined as: CTD = -65±5°F, dry RTD = 70±10°F, room temperature dry ETD = 250±5°F, dry ETW = 250±5°F, wet (equilibrium moisture content) Within each test method and test environment, the failure mode was evaluated immediately after each test by an FAA DER. All tested specimens were digitally photographed after each test in order to pictorially document failure modes. Representative photos are included in the CD accompanying this report. For dry testing, specimens were dried at 160°F±5°F for 120 to 130 hours. After drying, specimens were kept in a desiccator until mechanical testing. Alternatively, the specimens may have been left ambient laboratory condition for a maximum of 14 days until mechanical testing (no drying was required if specimens were tested within 14 days CAM-RP-2009-015 April 22, 2011 Revision A Page 25 of 238 from the date they were cured). Ambient laboratory condition is defined as 70°F±10°F. Since moisture absorption and desorption rate for epoxy is very slow at ambient temperature, there was no requirement to maintain relative humidity levels. For wet conditioning, specimens were dried at 160°F±5°F for 120 to 130 hours before being conditioned to equilibrium at 160°F±5°F and 85% ± 5%. Effective moisture equilibrium was achieved when the average moisture content of the traveler specimen changed by less than 0.05% for three consecutive readings which are 7 ±0.5 days apart and may be expressed by: 0.0005 < W W - W b 1 - i i where: Wi = weight at current time Wi – 1 = weight at previous time Wb = baseline weight prior to conditioning When representative specimens could not be measured to determine the moisture content (due to size, fastener and tab effects), traveler coupons of at least 1” by 1” by specimen thickness and weighing at least 5 grams were used to establish weight gain measurements. If the specimens or traveler coupons pass the criteria for three consecutive readings which are 7 ±0.5 days apart, the specimens were kept in the environmental chamber for up to an additional 60 days. Alternatively, the specimens may have been removed from the environmental chamber and placed in a sealed plastic bag along with a moist cotton towel for a maximum of 14 days until mechanical testing. Strain-gauged specimens were removed from the controlled environment for a maximum of 2 hours for application of gages in ambient laboratory conditions. CAM-RP-2009-015 April 22, 2011 Revision A Page 26 of 238 1.5.6 Non-ambient Testing The chamber was of adequate size so that all test fixtures and load frame grips were contained within the chamber. For elevated temperature testing, the temperature chamber, test fixture, and grips were preheated to the specified temperature. Each specimen was heated to the required test temperature as verified by a thermocouple in direct contact with and taped to the specimen gage section. The heat-up time of the specimen did not exceed 5 minutes, unless otherwise specified in individual test summary sheets. The test was started 1 0 2 + − minutes after the specimen reached the test temperature. During the test, the temperature, as measured on the specimen, was within ±5°F of the required test temperature. For subzero temperature testing, each specimen was cooled to the required test temperature as verified by a thermocouple in direct contact with and taped to the specimen gage section. The test started 1 0 5 + − minutes after the specimen reached the test temperature. During the test, the temperature, as measured on the specimen, was within ±5°F of the required test temperature. CAM-RP-2009-015 April 22, 2011 Revision A Page 27 of 238 1.5.7 Fluid Sensitivity Screening Table 1-4 lists the requirements for fluid sensitivity screening, which requires ASTM D2344 Short Beam Strength testing on [0°]34 lamina level specimens dried at 160°F±5°F for 120 to 130 hours before being subjected to the conditions indicated, five replicates per fluid and one cure cycle. Specimens were cleaned with a dry towel prior to the tests. In addition to short beam strength, load versus displacement curves were plotted to aid in the identification of matrix/resin softening. Since load versus displacement curves are influenced by test machine and fixture compliance, all the tests were performed with the identical machine and fixture, through a single setup. Experience suggests that for the vast majority of epoxy resins, water is the fluid with the most deleterious effect on properties. Should screening tests for fluid sensitivity indicate this to be the case, further testing of this type might be unnecessary since exposure to water moisture to equilibrium level is an inherent part of the multi batch allowables test program. However, users must evaluate the applicability of the exposure conditions and time on case-by-case basis.

Lamina level properties that were not normalized include 90º tensile strength and modulus (unidirectional only), 90º compressive strength and modulus (unidirectional only), in-plane shear strength and modulus, Poisson’s ratio, SBS, and ILT. After normalizing, data scatter reduced or remained the same. If data scatter increased significantly after normalizing, the reason was investigated. Wherever properties are normalized, both measured and normalized data were reported. For unidirectional materials the fiber areal weight cannot be measured in advance of impregnation, hence Method I of ASTM D3171, utilizing acid digestion, will be used to verify the CPT method in accordance with note (2) of Table 1-3. Method I Fiber Volume (%vol) is 58.535 and Method 2 Fiber Volume (%vol) is 59.405. By comparing Fiber Volume values obtained from Method I and Method II, the values are deemed close enough therefore the FAW is close to the nominal of ~190 gsm. Based on the FAW data from Hexcel (Avg ~190 gsm) and our Method I Phys test data (Avg. void content ~ 0% except for a panel where it is close to 4%) it is appropriate to use the CPT Method for normalization. The average cured ply thickness of 0.0072 inch has been used as the nominal cured ply thickness (CPT) for normalization purpose. The following normalization formula was used: Normalized Value = Measured Value x Measured CPT / Nominal CPT. Prior to beginning the qualification program, we predicted the cured ply thickness value to be 0.0074 inch. However, the as-measured cured ply thickness of the qualification and the equivalency panels are 0.007174 inch and 0.007293 inch, respectively (please review the attached file for cured ply thickness calculation). The grand average of all qualification and equivalency panel thickness is 0.007229 inch. A vote was taken among the material users, and 3 out of the four participating companies agreed that 0.0072 was an acceptable CPT. Not all companies cast a vote. CAM-RP-2009-015 April 22, 2011 Revision A Page 31 of 238 1.5.9 Conformity The 3-batch qualification panels have been fabricated according to the requirements of the test plan and conformed by the FAA. The test specimens and test setups have also been conformed by the FAA. Testing was witnessed by the FAA. Witnessing was delegated to a DER. Mechanical testing was carried out at the National Institute for Aviation Research, Wichita State University. The test setup and procedures were reviewed by NCAMP IAB and NCAMP staff during a facility audit. FAA conformity inspection records and approvals are included in the CD accompanying this report. 1.5.10 Material Pedigree Information The PMC Data Collection Template includes the material pedigree information required, such as material and batch information, as well as panel fabrication record, environmental conditioning, test equipment, and test procedures.
