抄録

In the previous papers, the authors have studied strength deterioration of injection-molded short glass fiber reinforced polyamide 6 due to the addition of a slight amount of titanium dioxide on the basis of micromechanics. This paper is concerned with the influences of quantities and kinds of inorganic addition agents on the strength deterioration. It was found that the strength deterioration depends on the hardness of inorganic addition agent and scarcely depends on the amount. The strength reduces as the hardness of inorganic addition agent becomes higher. Finally the strength deterioration of unnotched composites and maximum load of the notched ones were numerically predicted. Good agreement was found between the predicted and experimental results.
