Toughening Mechanisms in Fiber Containing Impact Modified Polymers

Document Type

Conference Proceeding

Publication Date



An attempt was made to separate the toughening arising from the presence of fiber and that from the toughened matrix using the essential work of fracture. Toughening mechanisms with fiber inclusions were found to be associated with fiber bridging, debonding and pull-out. It was concluded that such fiber toughening would yield a flat curve when the specific total fracture work was plotted against the ligament length. The technique was able to produce fruitful information regarding design for property synergism in impact modified nylon 6,6.
