REINFORCED SHAPE AND ITS MANUFACTURE

摘要

A method of producing a moulded article provided with reinforcement in selected portions of the article comprising moulding a thermoplastic polymeric material in a mould cavity containing reinforcing material characterised in that the reinforcing material in the mould is at least one preformed element comprising reinforcing fibres substantially totally embedded in a thermoplastic polymeric matrix, the preformed element having sufficient form stability to enable it to be located and restrained in the mould cavity to provide reinforcement in pre-selected portions of the moulded article. Distortion of the moulded article arising from the presence of the reinforcing insert is avoided by symmetrical disposition of the elements within the moulded article.
