Problems solved by technology

Thermosetting resin-based composite materials have the advantages of high specific strength, high specific modulus, small specific gravity, and chemical corrosion resistance. However, thermosetting resins undergo chemical changes after heating, and gradually harden and form. Therefore, thermosetting resin-based composite materials are not recyclabl

Example Embodiment

[0024] Example 1

[0025] Such as figure 1 As shown, clean the luggage mold 1 (clean the mold with acetone), then paste the sealing tape 2 according to the shape and size of the luggage, and then apply the release agent, and place the cut carbon fiber prepreg 3 on the coated release agent After placing the specified number of layers on mold 1 (1 layer of plain carbon fiber prepreg with a thickness of 0.2mm), place toughening material 4 (toughening material with a thickness of 0.2mm), and then continue to place carbon fiber prepreg The laying of carbon fiber prepreg is 1 layer. After completion, the isolation film 5 (the isolation film can cover the prepreg in the box) and the air felt 6 are placed, the system is sealed with a vacuum bag 7, and then the system is hot pressed The tank is cured in accordance with the curing system (curing for 30 minutes under 0.6MPa pressure and 150°C), and after cooling down, the mold can be demolded to obtain a well-shaped toughened carbon fiber ...

Abstract

The invention relates to a composite material toughed by a flexible material for cases as well as a preparation and application thereof. The composite material also comprises a flexible material, and the flexible material is paved between a piece of fiber fabric or a prepreg. The flexible material is paved between the fiber fabric or the prepreg, after paving the layers, moulding and solidification are carried out, and the toughed composite material for cases is obtained. The special flexible material paving layer is added into the composite material paving layer, appearance and performance of the product are not influenced, toughness of the product is greatly improved, impact resistance of the case housing is greatly improved, the service life is increased, and noise during skidding is reduced.

Description

technical field [0001] The invention belongs to the field of luggage materials and its preparation and application, in particular to a composite material toughened by flexible materials for luggage and its preparation and application. Background technique [0002] With the gradual development of the application of composite materials, the application of composite materials in bags is gradually increasing. At present, most of the bags are made of epoxy resin-based carbon fiber composite materials, which are thermosetting resin-based composite materials. Although the weight is lighter than traditional bags, because the resin is thermosetting, the products are relatively brittle and will be easily impacted by external forces. Cause damage to the product, resulting in product destruction. In response to this problem, this patent combines the characteristics of the composite material molding process and the excellent designability of the composite material, and adds a flexible m...
