Embodiment Construction

[0029] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.

[0030] see figure 1 I-shaped ribs and Figure 2 ~ Figure 6 A compression molding mold assembly for a thermoplastic composite member with I-shaped ribs, the compression molding mold includes a flat plate prefabricated part mold 1, a C-shaped prefabricated part mold 2 and an I-shaped reinforced component mold 3, used for the flat plate prefabricated part mold When several thermoplastic composite material prepreg sheets stacked together are pressed into a flat plate preform 10, the C-shaped preform mold is used to press the flat plate preform 10 into a C-shaped preform 20. In this embodiment, the C-shaped preform Part 20 includes a left side C-shaped prefabricated part 43 and a right side C-shaped prefabricated part 44, and the I-shaped reinforced member mol...

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...
