Description

Composite reinforcement structure

This creation is related to the application of composite materials, especially a composite reinforcement structure.

The composite material is made of at least two materials through composite technology, in order to be compatible with the advantages of various materials, to learn from each other to meet different needs of use, for example, but not obvious to carbon fiber composite materials, its advantages of high hardness, light weight, and high temperature resistance , Widely loved by various industries, especially aviation, automobile industry or sports equipment related industries have launched related products.

Among the carbon fiber composite materials mentioned above, most of the products are interlaced weaving, or stacked layer by layer with various arrangement angles to strengthen the overall structure. However, this layer-by-layer strengthening method will result in the disadvantages of excessive weight, too many layers, and thick thickness of the composite material.

Therefore, it is necessary to provide a novel and progressive composite material reinforcement structure to solve the above-mentioned problems.

The main purpose of this creation is to provide a composite material reinforcement structure, which can strengthen the structure at least partially in order to reduce the consumption of the overall material, thereby achieving the advantages of light weight and sturdiness.

In order to achieve the above-mentioned purpose, this creation provides a composite reinforcement structure, including: a matrix and a reinforcement structure. The matrix includes a first fiber layer and a second fiber layer. The first fiber layer and the second fiber layer are stacked and combined with each other along a stacking direction. A side of the first fiber layer facing away from the second fiber layer is defined as An outer surface, a surface of the second fiber layer facing away from the first fiber layer is defined as an inner surface; the reinforcing structure includes a plurality of reinforcing ribs, and the plurality of reinforcing ribs integrally protrude from the inner surface along the stacking direction, The plurality of reinforcing ribs are alternately connected to each other to form a plurality of concave lattice parts.

It can effectively increase the structural rigidity of the protected part and make it have excellent resistance to external forces. In addition, at the larger recessed portion 22, the base 1 is relatively easy to bend, and can correspond to the part where the contour of the covering changes greatly, so that the base 1 can be closely attached to the covering.

The reinforcement structure 2 further includes a boundary rib 23 that defines a reinforcement space 24. The plurality of reinforcement ribs 21 are connected to each other in the reinforcement space 24, and the reinforcement space 24 is divided into the plurality of concave grid portions 22. ; Among them, part of the plurality of reinforcing ribs 21 are connected to the boundary ribs 23 to have a more continuous and complete structure.

More specifically, the plurality of reinforcing ribs 21 includes a first reinforcing portion 211 and a second reinforcing portion 212. Along the stacking direction, the width of the second reinforcing portion 212 is greater than the width of the first reinforcing portion 211 , The width of the boundary rib 23 is between the width of the first reinforcing portion 211 and the width of the second reinforcing portion 212, and the reinforcing strength of the reinforcing rib 21 can be controlled through the change of the width to perform a more delicate degree of reinforcement Adjustment, it can be understood that the widths of the first reinforcement portion 211, the second reinforcement portion 212, and the boundary rib 23 are not limited to the foregoing, and the foregoing is only one embodiment, and the actual application is based on the needs of the user. Make adjustments for the main. It should be emphasized again that the adjustment of the degree of reinforcement can be further coordinated with the size change of the plurality of concave grid portions 22 to form a dense distribution to adjust and control. The denser the denser the better the strengthening effect and the higher the structural rigidity.

In the direction of the stacking direction 4, the thickness of the first fiber layer 11 is greater than the thickness of the second fiber layer 12. From a microscopic point of view, in this embodiment, the first fiber layer 11 is continuous Fiber layer, the second fiber layer 12 is a discontinuous fiber layer, that is, the reinforcing structure 2 is composed of discontinuous fibers. Specifically, the first fiber layer 11 includes a plurality of long fibers 111, which are arranged in the same direction, or are further laminated at different angles to serve as a strength reference of a continuous structure, and are combined with the plurality of reinforcing ribs 21 To further strengthen the structural strength, the second fiber layer 12 includes a plurality of short fibers 121, adjacent groups of the short fibers 121 constitute a plurality of short fiber groups 122, the plurality of short fiber groups 122 are arranged in any direction and on the inner surface 14 forms a pattern structure 3, so that the user can recognize the inner surface 14 by visual observation, and the pattern structure 3 is beneficial to increase the contact area with the covering, so that the base 1 can be tightly Paste on the covering. What is important is that the plurality of short fiber groups 122 along any direction help strengthen the second fiber layer 12 (including the reinforcing structure) to withstand forces from different directions; at the same time, the plurality of short fiber groups 122 arranged randomly It can produce higher density to strengthen the structure hardness.
