Embodiment Construction

[0037] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0038] like figure 1 As shown, the present invention is a mold for molding composite T-shaped long truss reinforced wall panels, which is characterized in that the mold includes a rigid module 1 and a flexible module 2, and the rigid module 1 and the flexible module 2 are positioned by magnetic force and fixed;

[0039] The rigid module 1 is used for the preforming of the L-shaped prepreg layup on one side of the T-shaped stringer, the assembly and curing of the T-shaped stringer, and ensures the positional degree, axis degree and surface quality of the T-shaped stringer;

[0040] The flexible module 2 is used to promote the effective transfer of the applied pressure to the T-shaped stringer corner area and the triangular area through the flexible module 2 respectively along the flange and the web, so as to ensure the prepreg...

Abstract

The invention belongs to the field of technological manufacturing and particularly relates to a mold and technology for forming a composite T-shaped stringer stiffened wallboard. The mold comprises a rigid module and a flexible module arranged at the end of the rigid module, the end of the rigid module and the end of the flexible module are each arranged to be in a wedge shape, and the rigid module and the flexible module are positioned and fixed through pre-buried magnets. By adopting the technological scheme, the rigid module is combined with a base and can be used for preforming of a hot membrane; the rigid module and the flexible module are easy to position and fix by adopting the pre-buried magnets; the rigid module is of an open type structure and is easy to demold; and through the scheme, impressed pressure can be promoted to be transmitted to a corner area and a triangle area of a stringer along a flange and a web through the flexible module, the effect that the forming pressure of fibers in the areas meets the solidification requirement is ensured, fiber compaction is facilitated, and the situation that pores and other defects occur due to the fact that the pressure in the corner area and the triangle area are transmitted in place is effectively avoided.

Description

technical field [0001] The invention belongs to the field of process manufacturing, and particularly relates to a method for promoting the effective transmission of external pressure to the corner area and the triangle area of ​​the stringer along the flange and the web through the flexible module, so as to ensure that the forming pressure of the fiber layup in the corner area of ​​the stringer and the triangle area meets the curing requirements. It is required to promote fiber compaction and effectively avoid defects such as pores in the corner area and triangular area due to insufficient pressure transmission. The mold for forming composite T-shaped long truss reinforced wall panels. Background technique [0002] T-shaped stringers are widely used in composite material reinforced wall panels. Composite material reinforced wall panels are generally integrally formed by co-curing or co-gluing. During the forming process, the mold is very important to effectively transmit th...
