A Charpy impact and frozen tongue evaluation of acrylonitrile-butadiene-styrene (ABS) copolymer

In this study, the fracture properties of Acrylonitrile-Butadiene-Styrene ( ABS) are compared with those of Styrene-Acylonitrile (SAN). The SAN materia l is the same type and grade as used for the matrix material of ABS. The fr acture characteristics of ABS are non-linear and those of SAN are Linear-el astic. Also, the relationship between crack initiation and crack propagatio n in ABS differ from those of SAN. To study these differing qualities of AB S and SAN, both the Charpy and frozen tongue fracture methods are used. The effect of the rubber particles in ABS at all stages of fracture is well in evidence. (C) 2000 Elsevier Science Ltd. All rights reserved.
