Embodiment 1
[0033] This example provides Figure 2~3 The molding tooling for an integral joint of composite materials shown includes an L-shaped vertical edge 2 and a joint bottom plate 1 combined into an integrated joint, and the L-shaped vertical edge 2 is made by a lay-up mold in the prior art , also includes a rubber soft mold 4 for integral joint shaping and a curing assembly molding mold for pressurization and fixing. The outer surface of the " font integral joint is used as its inner surface to make soft rubber mold 4.
[0034] Such as image 3 As shown, the soft rubber mold 4 is provided with four pieces in total, and the four soft rubber molds 4 are assembled into a "ten" shape structure on the base 7. The sides of each soft rubber mold 4 are close to the L-shaped vertical edge 2, and the bottom is Close to the joint bottom plate 1, the top of the soft rubber mold 4 is inlaid with a metal insert 5, generally a steel insert, and the metal insert 5 is provided with a penetrating ...
Embodiment 2
[0037] This embodiment provides a molding method for an integrated joint of composite materials, which is formed by using a molding tool for an integrated joint of composite materials described in Example 1. The forming process will use lay-up molds, soft mold forming molds and curing Assemble the forming mold. Specifically include the following steps:
[0038] a. Using the outer surface of the integrated joint as the inner surface of the soft mold forming mold to manufacture the mold body of the soft mold forming mold;
[0039] b. Place the rubber soft mold 4 on the soft mold forming mold, and complete laying and assembly vulcanization together with the metal insert 5 with a through hole to obtain the rubber-metal insert 5 soft mold; A through hole is set on the insert 5, and when the soft rubber mold 4 is vulcanized, the rubber will enter the through hole in the metal insert 5, thereby being combined with the steel insert;
[0040] c. Lay up and compact the prepreg blanks ...
