Problems solved by technology

[0003] At present, the traditional metal hard tooling is generally used in the mandrel of T-shaped reinforced siding and truss in China. At the same time, due to the relative position requirements of the truss and the siding, the tooling needs to be equipped with a certain positioning device. This metal mandrel and composite Due to the poor matching of the thermal expansion coefficient of the material and the complicated positioning device, the metal core mold cannot uniformly transmit the curing pressure during the curing molding process, and it is difficult to accurately control the curing pressure on the stringer
As a result, the thickness of the stringer is not uniform, and the internal quality is not ideal

Abstract

The invention provides a composite material T-shaped reinforced wall board co-gluing molding process, comprising steps: laying the wall board; making a vacuum bag; curing the wall board; laying and pasting the T-shaped stringer; Pre-assembly; vacuum bagging; pre-forming of T-strings; co-gluing of T-strings to siding; vacuum bagging; T-string assisted forming; curing; and demoulding. The process of the composite material T-shaped reinforced wall plate product formed by the method of the invention has good process repeatability, and the position degree of the T-shaped stringer, the internal quality of the product, the thickness of the product, etc. can be effectively guaranteed.

Description

technical field [0001] The invention belongs to the field of composite material manufacturing, and in particular relates to a co-gluing molding process of T-shaped reinforced wall panels of composite materials. Background technique [0002] Compared with traditional materials, composite materials have the characteristics of free design of material performance indicators, consistency of materials and structures, and freedom of product shape design. Due to its advantages of light weight, high strength, good fatigue resistance, good vibration reduction, and strong designability, modern civil aircraft body structures use a large number of composite materials, greatly expanding from non-load-bearing and secondary load-bearing components to the main load-bearing force of the empennage. Then to the application of the main load-bearing components of the wing and fuselage. For the main load-bearing components of composite materials, the reinforced panel structure composed of skin an...
