Abstract: Effects of various resins, fabrics and thickness on resin content of glass-fiber reinforced plastic (GFRP) molded by vacuum assistant resin infusion process (VARI) were studied in this paper. Experimental results indicate that resin content of GFRP prepared with triaxial-fabrics is higher, while resin content of GFRP prepared with biaxial-fabrics and unidirectional-fabrics is lower. The resin content of GFRP prepared with high viscosity resin (LR135/LH135) is lower, while resin content of GFRP prepared with low viscosity resin system (035C/037) is higher. When the thickness of fabric increases, resin content of the GFRP decreases.

Key words: resin content, resin type, fabric type, fabric thickness
