Abstract


The diameter of glass fiber chopped strands used for injection molding is usually from 10μm to 15μm. On the other hand, some reports have stated that the mechanical property is improved by slimming the diameter of the glass fiber chopped strands. By increasing the surface area between the glass fiber and matrix resin, in other words, an increase in the interface to bear the load is the main factor of this improvement. However, their report focused on the short-term load, so the effect on the durability strength has not been reported. This study was made to investigate the effect on the durability property by using low diameter fibers. In addition, we investigated the effect of using high strength and high modulus glass composition fibers on the durability property.
