Embodiment

[0044] A method for rapid prototyping of reinforced ribs in resin-based composites, such as figure 1 As shown, the cross-section of the main body of the reinforcement rib to be formed is L-shaped; the vertical rib in the middle is used to further improve the stiffness of the reinforcement rib, and the reinforcement fiber between the main body and the main body is required to be as continuous as possible to fully exert the mechanical effect of the vertical rib; the product The wall thickness is 3mm, and the carbon fiber reinforced epoxy resin pre-impregnated non-weft cloth is used to lay up symmetrically to form quasi-isotropy, and the outer surface of the main body of the product is a circular arc surface.

[0045] The steps of the molding method are:

[0046] 1) Prepare the forming mold: such as figure 2 , the forming mold includes counter-die A, counter-die B and positioning pins; the sides of counter-die A and counter-die B are used to form the reinforcement rib main body...

Abstract

The invention belongs to the technical field of formation of carbon fiber reinforced resin matrix composite structures, and relates to a forming method of resin matrix composite reinforcing ribs, which is particularly suitable for reinforcing ribs with maximum overall dimension smaller than 500mm. The forming method of the resin matrix composite reinforcing ribs, disclosed by the invention, is simple, convenient and easy to carry out; a used forming die is simple and easy to obtained, and has adaptive capability to different product sizes, and the appearance of obtained products is smooth and elegant; the method is particularly suitable for formation of serial reinforcing ribs, and the advantages are more prominent when the number of the reinforcing ribs is greater; multiple identical die assemblies can be manufactured continuously, meanwhile the method can be used for forming multiple reinforcing ribs with different structures, and different demands of the same structure system can be met quickly.

Description

technical field [0001] The invention relates to a molding method of a reinforced rib of a resin-based composite material, which is particularly suitable for a reinforced rib whose maximum external dimension is below 500mm, and belongs to the technical field of structural molding of a carbon fiber-reinforced resin-based composite material. Background technique [0002] With the rapid development of structural technology, the utilization rate of resin-based composite materials has been increasing, and the application forms have also been greatly expanded, from simple panels and round tubes to support beams, corner boxes, and even special-shaped parts. However, the forming methods of these parts with different shapes, especially the rapid prototyping method, have become an obstacle restricting the further popularization and use of resin-based composite materials. [0003] In order to solve the molding problem of resin-based composite materials, especially the molding of special...
