FIELD: chemistry.
SUBSTANCE: invention relates to production of unidirectionally reinforced thermoplastic prepreg. Distinctive feature of the thermoplastic prepreg manufacturing is that providing the reinforcing fibre uniform flattening in the flattening system, with subsequent formation of thermoplastic prepreg by pulling it through pultrusion head with possibility of adjustment of gap at inlet and outlet of impregnation channel by rotation of adjusting screws of movable opening top plate to achieve required pulling force and geometric parameters of prepreg at outlet of spinneret. Pultrusion head has a multichannel system for feeding plastic along the entire length of the impregnation channel, which ensures efficient impregnation of the fibre with the matrix at different positions of the movable plate.
EFFECT: possibility to produce prepreg with different geometrical and physical parameters of pultrusion without change of equipment with provision of efficiency of prepreg impregnation.
