Effect of Constituent Materials on the Impact Properties of CFRTP Composites

Abstract
Composite materials are commonly used in industry because they have great properties with a combination of reinforcement and matrix material. For example, an aircraft is made of glass fiber composite since it has high toughness, impact resistance, and high modulus. On the other hand, carbon fiber composite which has high strength and low density is mostly used in automotive and bicycle frames. Those excellent properties can be exhibited when the fibers are combined with the specific matrixes. In this research we focused on two different composites fabricated with polyphenylene sulfide (PPS), and polyamide 6 (PA6). Both PPS and PA6 are semi-crystalline, however, PPS has higher service temperature and chemical resistance than PA6. PA6 is easier to fabricate than PPS because of its lower melting point. Four composite materials, which were CF/PA6, CF/PPS, GF/PA6, and GF/PPS were manufactured in quasi-isotropic layup by compression molding. The specimens were subjected to impact loading of 10J/mm, 15J/mm, and 20J/mm, following ASTM D7136, to determine their impact resistance, absorbed energy, and compression strength after impact. Results of the testing and analysis are discussed in this poster.
