Embodiment Construction

[0028] Taking the manufacture of honeycomb sandwich parts as an example, the specific process is as follows:

[0029] Such as Figure 1-Figure 4 Shown, comprise a group of upper anti-skid plate 6 and lower anti-skid plate 7, the structure of upper anti-skid plate 6 and lower anti-skid plate 7 is corresponding, all is the uneven surface with part contact side (anti-skid surface 4), and the other side ( The installation surface 5) is a smooth and flat surface, and used in pairs;

[0030] 1) Fix the lower anti-skid plate 7 in the spare part area 2 around the tooling 1, and the mounting surface 5 of the lower anti-skid plate 7 is in contact with the surface of the tooling 1;

[0031] 2) Evenly apply a release agent on the surface of the tooling 1 and the anti-skid surface 4 of the lower anti-skid plate 7;

[0032] 3) Starting from the surface of the tooling 1, lay the prepreg layer by layer, place honeycomb cores, inserts, secondary parts, etc., and the margin area of ​​each lay...

Abstract

The invention provides a ply slippage prevention method for composite material parts. The ply slippage prevention method for the composite material parts comprises a set of upper slippage prevention plates and a set of lower slippage prevention plates. The upper slippage prevention plates and the lower slippage prevention plates are used cooperatively. The faces (slippage prevention faces), which contact with the parts, of the upper slippage prevention plates and the lower slippage prevention plates are uneven surfaces and the other faces (installing faces) of the upper slippage prevention plates and the lower slippage prevention plates are smooth and flat surfaces. Plies are prevented from slippage by fixing composite materials with the upper slippage prevention plates and the lower slippage prevention plates. The device used by the method is simple in structure and convenient to use; the problem of slippage of the plies, honeycomb cores, inserting blocks, secondary parts and the like during the lay-up, bag-making and solidifying processes can be solved and the quality of the products can be improved.

Description

technical field [0001] The invention relates to the field of manufacturing composite material parts, in particular to a layer-laying anti-slip method for composite material parts. Background technique [0002] Thanks to its excellent comprehensive mechanical properties and performance, in recent years, composite parts have been widely used in aviation, aerospace, wind power, shipbuilding and other fields, and the manufacturing technology of composite parts has developed rapidly. Although various new processes and methods represented by liquid forming emerge in an endless stream, the autoclave process is still a common method for manufacturing composite parts. [0003] For the autoclave process, part molding is mainly divided into two stages: 1) laying; 2) curing. In the laying stage, raw materials such as prepreg or metal layup need to be laid and compacted layer by layer according to the design requirements. For some parts with more complex structures, it is also necessar...
