Test Background
fiber-reinforced plastic impact compression test can determine the post-impact compressive strength of continuous fiber-reinforced plastic laminates with multiple fiber directions that are balanced and symmetrical relative to the test direction.
Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various fiber-reinforced plastics and provides professional laminate impact compression testing services for fiber-reinforced plastic laminates.
Scope of tests
Commonly used fiber-reinforced plastics include polypropylene (PP), polyethylene (PE), polyester (PET) and other high-molecular polymers and high-purity natural wood, as well as some man-made fibers (cellulose fibers), glass-reinforced resins and metal fibers.
It can be divided into three categories according to its molding methods: thermoplastic resin, thermosetting resin, and polycarbonate.
Test method
After the rectangular sample is impacted with a certain energy at the center of the sample along the thickness direction, a compressive load is applied to the sample along the length direction until the sample fails.
