The Automotive thermoplastic industry has seen the introduction of Long Glass Fiber (LGF) composites during the past several years, offering specific performance advantages over short glass fiber thermoplastic grades. The need to develop stronger, lightweight, and cost-competitive materials is critical for the industry in meeting C.A.F.E. requirements of the future. The intent of this paper is to supply design engineers with long term performance data for several LGF thermoplastics at various elevated temperatures, shown in comparison to short glass fiber (SGF) composites. The study will evaluate long-term tensile property performance at 200° F, 275° F, and 300° F. At these temperatures, advantages should be realized over SGF composites when using LGF polypropylene, nylon 6/6, and polyphthalamide (PPA) thermoplastic composites, respectively.
