Embodiment Construction

[0035] The technical solutions in the embodiments of the present invention will be described in conjunction with the drawings in the embodiments of the present invention.

[0036] Such as Figure 1 to 6 As shown, the present invention provides a composite curved thin plate forming method, including the following steps.

[0037] Step S1, according to the shape of the composite material, a composite curved sheet molding die is fabricated, and the composite curved sheet molding die includes a base 20 and a cover 30; the base 20 is provided with the inner cavity 21 and the sealing groove 22, the shape of the inner cavity 21. Matching the shape of the composite material requires a shape, the sealing groove 22 is arranged on a circle side around the inner cavity 21; the upper cover 30 is provided with a pneumper interface 31, and the air nozzle interface 31 conducts two surfaces opposite to the cover 30;

[0038] Step S2, according to the shape of the composite material, the silica gel g...

Abstract

The invention discloses a composite bent sheet forming method and mold. The forming method is characterized in that a base and an upper cover are used for compressing a silica gel gasket to form a sealing structure capable of being inflated from the outside, an inflation interface of the upper cover is inflated and pressurized, so that the internal silica gel gasket expands to extrude a composite and is heated, cured and formed at the same time. According to the scheme, the requirement for production equipment is low, manufacturing is simple, cost is low, environment friendliness is achieved, the manufactured carbon fiber product is little in later rework, good in quality and high in yield, and the problem that an existing forming method cannot give consideration to machining quality and cost is practically solved.

Description

Technical field [0001] The present invention relates to the field of composite material, and more particularly to a composite curved thin plate forming method and a mold. Background technique [0002] Advanced composites have a range of strength, specific modulus, excellent corrosion resistance, fatigue resistance, and design, etc., the thin plate made of composite materials, high cost, mostly used in the aviation field, Strap with non-metallic material housing, decoration, etc. in various fields. [0003] At present, the molding process of the composite curved plate material is mainly hot press molding and vacuum hot pressing tank heating curing molding. The work arts made by these two methods are good, but the cost of investment is high. High molding efficiency, simple operation, high quality requirements, long-term preparation cycle; vacuum hot tank heating curing molding is more troublesome, low efficiency, and vacuum bag cannot be reused, very Not environmentally friendly. ...
