概要

As there are very few studies on fracture mechanisms of short fiber reinforced composite materials, this study is conducted for the purpose of clarifying the fracture mechanisms of short fiber reinforced polyethylene terephthalate (FRPET) by the acoustic emission method in the cases in which the loading direction to the injection direction and the fiber content are different. It is found that in the test specimens in which the angles between the loading direction and the injection direction are 0°(parallel) and 90°(perpendicular), the resin cracking is dominant damage mode, and that in the test specimen of 45°, fiber breaking is dominant. It is also found that in the test specimens of lower fiber content by weight of 15% and higher content by weight of 45%, fiber debonding and pulling-out is dominant.
