<p>A process for manufacturing a composite injection moulding consists of the steps of positioning a preform fibre core in a mould tool, and injection moulding a thermoplastic into and around the preform to form a thermoplastic matrix. The composite moulding includes at least 90% by weight of the fibres retained in the preform fibre core longer than 2mm, and the thermoplastic material which forms the thermoplastic matrix has a melt flow volume greater than 50 dg/min. Depending upon the intended application, at least 90% by weight of the fibres retained in the preform fibre core may be up to greater than 20mm in length, and the thermoplastic material which forms the thermoplastic matrix may have a melt flow volume of up to 800 dg/min.</p> |
