Embodiment Construction

[0029] Such as figure 1 As shown, the lightweight high-strength advanced composite material structure includes a first outer layer 10, a second outer layer 20, a reinforcement member 30, a support member 40 and an inner layer 50, and the reinforcement member 30 is arranged on the first outer layer 10 and the second outer layer 10. between the ends of the outer layer 20 . The number of inner layers 50 is multiple, and they are sequentially stacked between the first outer layer 10 and the second outer layer 20, wherein a plurality of inner layers 50 are bonded together, and the inner layers 50 are respectively bonded to the first outer layer 10. It is also connected with the second outer layer 20 by bonding. refer to figure 2 , the support member 40 includes a first surface 41 and a second surface 42, the support member 40 passes through a plurality of inner layers 50, and the first surface 41 and the first outer layer 10 are bonded, and the second surface 42 and the second o...

Abstract

The invention discloses a lightweight and high-strength advanced composite structure. The lightweight and high-strength advanced composite structure comprises a first outer layer, a second outer layer, an inner layer, a reinforcing part and a support part, wherein the inner layer is arranged between the first outer layer and the second outer layer; the reinforcing part is arranged between ends ofthe first outer layer and the second outer layer, the support part comprises a first surface and a second surface, and penetrates through the inner layer, and the first surface is bonded with the first outer layer, and the second surface is bonded with the second outer layer; grooves are formed in the first surface and/or the second surface, and filled with resin, so that the support part is tightly connected between the first outer layer and the second outer layer respectively to prevent the first outer layer, the second outer layer and the inner layer arranged between the first outer layer and the second outer layer from being delaminated.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a lightweight high-strength advanced composite material structure. Background technique [0002] Composite materials have been widely used in aviation, aerospace, machinery, biology, medicine, sports and other cemeteries in recent years due to their high specific strength, specific stiffness, fatigue resistance, impact resistance, and designability. However, in practical engineering applications, high-speed and heavy-duty working conditions put forward higher design requirements for the strength and weight of composite components, and the designability of composite materials provides opportunities for further improvement in strength and weight and structural optimization. wide open space. Existing composite materials are all compounded by multi-layer materials. [0003] For example, the patent number is CN201620295297.3, and the patent name is a utility model pate...
