METHOD FOR MANUFACTURE OF PIPES FROM FIBROUS COMPOSITE MATERIALS WITH LONGITUDINAL REINFORCEMENT

摘要

FIELD: treatment with pressure of fibrous composite materials applicable in aerospace and other branches of mechanical engineering. SUBSTANCE: method for manufacture of pipes from fibrous composite materials with longitudinal reinforcement includes assembly of the billet directly on the mandrel, billet rigid fastening to the mandrel and their combined drawing through the die to compact the billet under isothermal conditions. In so doing, the length of the die working zone is taken within the range indicated in the invention description. EFFECT: considerable rise of productivity of the process for manufacture of longitudinally reinforced pipes from fibrous composite materials and reduced their costs due to cut down costs of equipment.
