Abstract

For the last decade continuous fiber reinforced thermoplastic composites (CFRTPC) have been inching their way into the composites’ marketplace as viable materials worthy of attention and respect. Known as thermoplastic tapes, organo-sheets and CFRTP, they are finding application in various industries ranging from sporting goods to aerospace. Their appeal is in their light weight, corrosion resistance, low-energy transportation and storage, and recyclability. Their mechanical properties along the fibers rival those of thermoset reinforced polymers. In addition, the advent of imidized materials and advanced engineering thermoplastics makes CFRTP true competitors in lightweight and high temperature applications.

The goal of this project is to expand on previous studies on optimization of CFRTP in terms the effect of fiber content and type of matrix material on impact, tensile and compressive properties. The focus of the proposed study will be on three major areas: drop weight impact properties, compression after impact properties and open-hole tensile and compression properties. All three areas are of interest in aerospace and other applications. Materials to be investigated include GF/PET, GF/PPS, CF/PPS, GF/PA6, CF/PA6 and CF/PA12 from Celanese and GF/PP from Avient. Samples are fabricated at WSU and tested at WSU using the Instron fatigue, impact, and static test equipment.
