Experimental Research on Bearing Strength and Effect Laws for Woven GFRP Composite Laminates

Abstract:

Based on ASTM D 5961 standard, the double-shear bearing strength and effect laws for woven glass fiber/vinyl resin composite laminates are studied. By testing of various specimen, bearing chord stiffness line is properly determined according bearing stress range, and effect laws on bearing strength are analyzed when (±45)°/(0/90)°plies proportion and fastener torque get changed. The results show, with 40%~60% (±45)°plies proportion, the bearing strength and the offset bearing strength simultaneously reach to the high value region with small fluctuation. As fastener torque increases, bearing strength increasing trend gets slow while offset bearing strength first increases and then decreases.
