Experimental Study on Static and Fatigue Behavior of a Short Glass Fiber Reinforced Polypropylene 2020-01-0190

One approach of lighting vehicle weight is using composite materials. Fiber reinforced polypropylene is one of the most popular composite materials. To improve accuracy in the prediction of durability performance of structures made of this kind of composite material, static and fatigue properties of a short glass fiber reinforced polypropylene have been physically studied. This paper describes details of test coupon design, fabrication, test setup of both quasi-static and fatigue tests, test results and discussions. In this study, various loading orientations (0o, 20o, 90o and knit line), temperatures (22oC/23oC and 80oC/85oC), loading ratio (R = -1.0, -0.5, -0.2, 0.1 and 0.4) are considered.
