2、 TENSILE MODULUS 1. SCOPE This specification defines the requirements for measuring selected material properties used in CAE simulation or equivalent modeling of automotive components made from thermoplastic production materials. 2. APPLICATION This specification was released originally to communica
3、te test methods and test parameters for material property data collection to the thermoplastic material suppliers. The data can then be combined with other material property data to model automotive components made from the material. 3. REQUIREMENTS 3.1 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS
4、 Material suppliers and part producers must conform to the Companys Standard Requirements for Production Materials (WSS-M99P1111-A). 3.2 SAMPLE PREPARATION Test specimens must be milled out of injection molded plaques with film gate injection on the short side. Plaque size should be approximately 25
5、0 mm x 150 mm x 3.0 mm. The specimens must not be taken from the edges or in the film gate area of the plaque to avoid the skin effects of the injection molding process. Specimen A 150 minimum x 10 x 4.0 +/- 0.2 mm (ISO 527-2, Type 1A) Specimen J 80 mm x 15 mm x 3.0 +/- 0.2 mm (ISO 8256, Type 3) Spe
6、cimen K 250 minimum x 25 x 3.0 +/- 0.2 mm (ISO 527-4, Type 2) 3.2.1 Number of samples The number of samples will be determined by Ford Materials Engineering, Ford CAE, and the material supplier based on the number of optional conditions selected. Supplement A is to be used to communicate the number
7、of optional test parameters included in the material testing. Laboratories capable of running the test methods are listed in the General Information section. 3.3 TENSILE MODULUS (ISO 527-4, Specimen K, 5 mm/minute, 23 C) Unreinforced Sample Orientation: 0 Report Modulus, GPa Fiber Reinforced Sample
