AE周波数解析によるABS成形板の破壊機構の解明

抄録

Fracture mechanisms for two kinds of ABS mold plates of copolymerized ABS and mechanically blended ABS are investigated on various mold temperatures and positions of the mold plate by means of acoustic emission (AE) frequency analysis. It can be found that, when the values of peak frequency represent the damage modes, the AS cracking dominates the fracture mechanisms of the copolymerized ABS, and the AS cracking and the B rubber aggregate/AS debonding dominate the fracture mechanisms of the mechanically blended ABS at final fracture.
