FIELD: process engineering.
SUBSTANCE: forming workpiece from alternating reinforcing and matrix fibers proceeds at temperature above that of binder melting. Said process is started by feeding pressure at temperature varying from matrix fiber heat resistance to complete transversal deformation of workpiece. Thereafter, pressure is reduced to the level sufficient for maintaining the workpiece in deformed state. Simultaneously, temperature is increased to matrix fiber melting point. Now at the same temperature, organoplastic material is cooled to be below heat resistance point of thermoplastic binder.
EFFECT: higher quality and efficiency, improved physical-and-mechanical properties, longer life, efficient and easy production.
