Compression molding die of thermoplastic composite component provided with I-shaped reinforcing ribs

Abstract

The invention provides a compression molding die of a thermoplastic composite component provided with I-shaped reinforcing ribs. The compression molding die comprises a base and one or more groups ofupper modules arranged on the base, wherein oblique planes with narrow upper parts and wide lower parts are arranged on left and right trapezoid strips of each of the upper modules; and the oblique planes with wide upper parts and narrow lower parts matched with the oblique planes of the left and right trapezoid strips are arranged on left and right wedge blocks. A group of oblique planes fittingeach other and sliding relatively is arranged on each of the left and right sides, so that the downward mould pressing pressure of a press cake is converted into the horizontal pressure pointing to the I-shaped reinforcing ribs through the left and right trapezoid strips, that is, the single vertical mould pressing pressure is converted into the mould pressing pressure in downward, left and rightdirections, the mould pressing pressure in the horizontal direction does not need to be additionally set, equipment and technology are simplified, rapidity and reliability are realized, and mass production of I-shaped reinforcing rib components of thermoplastic resin based composite is promoted.

Description

technical field [0001] The invention relates to the technical field of composite material molding, in particular to a molding die for thermoplastic composite material components with I-shaped reinforcing ribs. Background technique [0002] Thermoplastic resin-based composite materials (referred to as thermoplastic composite materials in this application) have good heat resistance, excellent damage tolerance, good impact resistance, short molding cycle, high production efficiency, and repeated molding. The aerospace field is gaining more and more attention. A class of advanced thermoplastic composite materials represented by carbon fiber reinforced polyether ether ketone is increasingly applied to the main / secondary load-bearing components in the aviation field. Poor performance and penetrability, difficulty in bonding between adjacent layers, difficulty in eliminating voids in the laminate, and difficulty in resin flow during the molding process, so the manufacturing of its...

AI Technical Summary

Problems solved by technology

In the autoclave, the pressure of the filled gas is used to form a uniform pressure on the composite material, so the molding of the I-shaped stringer of the composite material can be easily realized in the autoclave, but the equipment of the autoclave is expensive, and the molding cost is high, and The molding process is more complicated, time-consuming and labor-intensive, and it is difficult to meet the requirements of industrialization
