Comparison of the failure mode in short and long glass-fibre-reinforced injection-moulded polypropylene composites by acoustic emission

Research output: Contribution to journalArticle

Abstract

Acoustic emission and transmission light microscopy are used to investigate the failure of the title composites. It is shown that the short-fibre composites failed mostly through matrix deformation, along with fibre/matrix debonding and some fibre pull-out - failure did not alter with loading. With the long-fibre composites fibre fracture, fibre pull-out and debonding occurred - failure here was governed by fibre-related events.
