    摘要: A method of producing a fibre reinforced structure by melt impregnation of continuous fibres with a thermoformable polymer melt comprising pre-wetting the filaments of the fibres with a composition containing a melt plasticiser forthethermoformable polymer, priorto introducing the pre-wetted fibres into the melt, optionally removing the plasticiser when the composition contains a polymer miscible with plasticiserto leave polymer coated filaments and introducing the pre-wetted filaments into a polymer melt, optionally a polymer melt containing a melt plasticiser for the melt and preferably removing the plasticiser from the composition by volatilisation. The pre-wetted polymer coated filaments are useful materials as reinforcing fibres for use in processes other than direct melt impregnation. They can be used in the process known as film stacking impregnation or in processes involving initial impregnation using particulate polymers or alternatively in conventional extrusion compounding.
