Process	Hot pressing, composites
	Process used for shaping fibre reinforced thermoplastics. The material, usually a woven mat, is a mixture of plastic fibres and reinforcement fibres. When heated, plastic fibres melt and spread through the reinforcement. The mat is cut into dimension, and piled up until the desired laminate thickness is achieved. The laminate is then evacuated and placed in a mould where it is heated (380-400 C), and pressed into shape. For setting the shape, pressure (0.3-1 MPa) is maintained for about 5 minute. The part is cooled and removed from the mould.
