Novel Process Technologies for the Production of Hybrid Thermoplastic Composite Structures
A. Wood, Victrex Polymer Solutions, Thornton Cleveleys, United Kingdom
The overmoulding of metal components such as threaded inserts is well established in the automotive industry and, more generally, in the plastics industry. Overmoulding of long-fibre composite materials is however, relatively new. The current state of the overmoulding technology involves heating pre-consolidated laminate, sometimes referred to as ‘organo-sheet’, to a temperature where the matrix material fully melts. The laminate is then positioned into an open injection-moulding tool and the tool closed. As the tool closes, the laminate is formed to the desired shape and polymer is injected onto the surface of the laminate. Victrex Polymer Solutions have developed a poly(aryl ether ketone) [PAEK] which has a lower melting point than VICTREX® PEEK but retains properties similar to VICTREX PEEK. A composite with a matrix based on the new PAEK can be overmoulded with PEEK without the matrix being melted. The process results in a good bond between the laminate and the overmoulded material.
