Abstract

Abstract: PURPOSE: To investigate the effect of glass fiber volume content on the flexural property of fiber-reinforced composite. METHODS： The specimens of composite were fabricated with 4 different glass fiber volume contents by changing roving winded number of strands dipped in resin matrix, and the mechanical properties were tested by 3-point flexural test in order to determine the optimal fiber volume content. The data was analyzed statistically with SPSS20.0 software package. RESULTS: Self-made fiber-reinforced composites with the glass fiber volume content percentage of 60.4% achieved the maximal flexural strength and the maximal elastic modulus. CONCLUSIONS: As the glass fiber content in matrix of composite material is increased in certain range, the flexural strength and the elastic modulus can be improved，then reaches the peak. However, the flexural property decreases rather than rises when the fiber content is more than 60.4%.

Key words: Glass fiber, Composite material, Flexural strength, Elastic modulus
