Description / Abstract: GMW16652, 3rd Edition, March 2020 - Standard Test Methods for Quasi-Static Physical Testing of Injection Molded Short Fiber Reinforced Thermoplastics for Use in Finite Element Anisotropic Analysis

Purpose.

This standard provides information on the molding, testing and reporting of test data from injection molded short fiber reinforced thermoplastic plaques. The results allow a design analyst to characterize the anisotropic physical behavior in a material model to be used in finite element analysis. The test methods are as follows:

Method A:

Tensile testing to evaluate the anisotropic tensile behavior of test specimens cut from an injection molded thermoplastic plaque at 0 degrees, 45 degrees, and 90 degrees (see 7.1) to the flow direction.

Method B:

Thermal expansion testing to evaluate the thermal expansion behavior of test specimens cut from an injection molded thermoplastic plaque at 0 degrees and 90 degrees to the flow direction, as the sample is heated.
