METHOD FOR PRODUCING A THERMOPLASTICALLY DEFORMABLE, FIBRE-REINFORCED SEMI-FINISHED PRODUCT

摘要

The invention relates to a continuous method for producing a thermoplastically deformable, thin semi-finished product consisting of a thermoplastic and long reinforcement fibres. The method comprises the following steps: A. the thermoplastic fibres and reinforcement fibres are mixed in their dry state to form a mixed nonwoven, B. the mixed nonwoven is bonded by needling, C. the bonded mixed nonwoven is heated and D. pressed to form a semi-finished product on a calender or in a smoothing device.
