抄録

Tensile strength of injection-molded short glass fiber reinforced thermoplastics was remarkably decreased by the addition of a slight amount of titanium dioxide (TiO<SUB>2</SUB>) . Generally it is explained that the strength deterioration is due to much shortening of glass fiber length under processing, since the hardness of TiO<SUB>2</SUB> is higher than that of glass fibers. In this study, the influence of the addition of TiO<SUB>2</SUB> (0.2 wt%) to short glass fiber reinforced polyamide 6 on the strength of glass fibers in the composite was investigated. The tensile strength of the composite containing TiO<SUB>2</SUB> was fairly lower than that of the composite without TiO<SUB>2</SUB>, even if the glass fiber lengths in the composite were unchanged. However, numerous flaws were observed on the surface of glass fibers in the composite containing TiO<SUB>2</SUB>. After tensile test of the composites, the pull-out lengths of glass fibers were measured and the variation of Weibull moduli was estimated by using the data based on the Weibull weakest-link theory. As a result, the value of scale parameter decreased markedly by the addition of TiO<SUB>2</SUB>. Namely, it was found that the main factor of the strength deterioration of short glass fiber reinforced polyamide 6 containing TiO<SUB>2</SUB> was weakening of glass fibers.
