Abstract

A method of fabricating a composite component comprising positioning the uncured composite component between two mould parts, heating the component to a temperature in the range of 150-250°C and applying a pressure in excess of 5MPa to the component; wherein the pressure is increased over a period of 200-450ms. The pressure and temperature may be maintained for about 1minute ±30seconds to wholly cure the component. The high pressure and rapid application of pressure induces a high rate of cure without degrading the material. The method is particularly suitable for the short cycle time required by the automotive industry.
