| Abstract: | Unidirectional glass/polypropylene composites was fabricated in a hot press by using air jet commingled yarn of 50∶50 wt% glass fibers/polypropylene filaments. According to ASTM D792, the void content sample of composites was measured, and bending test of composites was performed on DCS500 tester by using three point loading system. Experimental results showed that the relation between void content and bending properties of air jet commingled yarn composites was a negative exponential function; meanwhile, the functions were various for different bending properties such as strength and modulus. |
