Description

C + K angle prepreg

Technical Field

The utility model relates to a preimpregnation material field, concretely relates to C + K angle preimpregnation material.

Background

Prepreg is a composition of a resin matrix and a reinforcement made by impregnating continuous fibers or fabrics with the resin matrix under strictly controlled conditions, and is an intermediate material for making composite materials. The prepreg made of the carbon fibers has good mechanical properties and is commonly used for reinforcing bridge structures or used as a component of automobile shells and mobile phone shells, but the prepreg made of the carbon fibers is easy to pierce and has poor safety.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

The utility model provides a C + K angle preimpregnation material solves current preimpregnation material to the not good problem of puncture protection effect at least, has good resistant puncture effect, and then the high advantage of security.

(II) technical scheme

In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a C + K angle preimpregnation material, includes the mixed layer that is woven and forms by first group's weft, first group's warp and the second group's warp, first group's warp and second group warp are constituteed by the carbon fiber, and first group's weft comprises aramid fiber, the mixed layer is according to first group's warp of carrying forward earlier, then wears first group's weft, supports second group's warp to weave again, and the repetitive cycle obtains carbon fiber cooperation aramid fiber's mixed layer in proper order, adjacent two first group's warp and adjacent two the interval homogeneous phase of second group's warp equals.

So set up, carbon fiber warp-wise intensity is high, latitudinal direction intensity is low, when whole carrying out the same mode by the carbon fiber and weaving, the easy problem that splits of breadth when can producing preimpregnation material and using, consequently with weft with aramid fiber substitution, aramid fiber intensity itself is high, weave the intensity that can improve effectively between warp, the weft after weaving with the carbon fiber cooperation, and then improve the mechanical strength and the stronger resistant puncture effect of preimpregnation material.

Further setting, first group warp and second group warp are parallel to each other to first group warp and second group warp all are mutually perpendicular with the weft, first group warp, second group warp and weft are woven and are formed mixed the layer after, and the mesh that forms is the rectangle.

According to the arrangement, as the distances between the two adjacent first groups of warps and the two adjacent second groups of warps are equal, the first groups of warps and the second groups of warps are parallel to each other, and the first groups of warps and the second groups of warps are perpendicular to the wefts, the rectangular meshes are easier to form relative to the circular meshes, and the rectangular meshes have better transverse or longitudinal tensile force resisting effect.

In the weaving process of the first group of warps, the second group of warps and the wefts, after one group of wefts are penetrated, a second group of wefts intersected with the first group of wefts are added, the second group of wefts are arranged on the first group of wefts, and then the second group of warps are lifted for weaving.

So set up, return after the mixing is woven and is accomplished and form the mesh of equidistance equidimension, through addding second group weft, reduce the size of mesh for the mechanical strength who mixes the layer is better, and resistant puncture is effectual.

Further, an epoxy resin layer is arranged on the surface of the mixing layer.

So set up, the epoxy resin layer is formed by mixing the layer infiltration in the epoxy glue that adds polyvinylidene fluoride, and polyvinylidene fluoride has splendid resistant chemical characteristic and high mechanical strength, can improve the corrosion resistance and the mechanical strength who mixes the layer effectively.

Further, after the epoxy resin layer is formed, an ultraviolet-proof layer is coated on the epoxy resin layer, and the ultraviolet-proof layer is a titanium dioxide coating.

So set up, because aramid fiber ultraviolet resistance is poor, ultraviolet radiation easily leads to aramid fiber to degrade, consequently, needs the protective layer, accessible coating titanium dioxide coating on epoxy layer, and then realizes that the protection mixes the layer and is difficult for receiving the ultraviolet interference.

(III) advantageous effects

Compared with the prior art, the utility model provides a pair of C + K angle preimpregnation material possesses following beneficial effect:

through the high mechanical strength who increases aramid fiber itself, its cooperation carbon fiber is woven to be provided with two sets of cross fit's aramid fiber, reduce the size of mesh, thereby increase the mechanical strength of preimpregnation material, overcome the problem that current carbon fiber preimpregnation material was impaled easily, and then obtained the carbon fiber preimpregnation material that has good resistant puncture effect.
