METHOD OF MAKING JOINTS BETWEEN COMPOSITE PARTS

摘要

FIELD: machine building.SUBSTANCE: invention relates to the method for joining of structural parts made from composite material and set perpendicular to each other. A flange and a wall of specified profile are used as the parts. Method involves the following stages at which: structural parts are placed in a mould in the desired position in relation to each other so that to form a joint area where the butt face or its neighbouring section of one of the structural parts rests against the other structural part, complete melting and run-out of the thermoplastic material into the joint area are provided. Afterwards the structural parts are fused together under the action of heat and excessive pressure. The structure and the filling element obtained by the proposed method form a joint area between two structural parts being connected. The said joint comprises plastic material in the form of a filling element on either side of the resting structural part and between the said resting part and the other structural part. At that the filling element comprises two halves and a bridge connecting them.EFFECT: technical result provided due to the usage of the method and structural part as per the inventions consists in ensuring the specified strength and rigidity of a structure at the specified thickness of composite parts.23 cl, 14 dwg
