Abstract

Considerable distortion has been observed in injection-moulded thermoplastic structural foams reinforced with short glass fibres, whereas this condition is not usually found in unreinforced or particulate-filled variants of this material. Consideration is given in this paper to the origin of distortion in short glass-fibre reinforced polypropylene structural foam, with reference to the influence of processing conditions, density and blowing agent concentration on this parameter. Results are discussed in terms of the structure produced in the material and in particular the effects of fibre orientation.
