Problems solved by technology

[0004] When the current SMC is molded, due to the internal stress formed by the uneven cooling of the inner and outer layers of the product after thermal demoulding, and the orientation of the chopped fibers, it is easy to warp the part; at the same time, in order to ensure the rigidity, the part needs to be thickened , not only increases the weight of the part, but also increases the cost; in addition, the SMC board is easy to crack and break when an accident occurs, which is easy to cause secondary damage and is not easy to repair

Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, and Not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] In the present invention, the sheet molding compound (Sheet Molding Compound, SMC) is mixed with resin, thickener, initiator, crosslinking agent, low shrinkage additive, filler, internal mold release agent and colorant to form a resin matrix, and then impregnated short Cut fiber roving or fiber mat, and cover it with polyethylene or polypropylene film on both sides. During production, th...

Abstract

The invention provides a flaky molded material-prepreg mixed composite material and a manufacturing method thereof. The flaky molded material-prepreg mixed composite material comprises a first flaky molded material outer layer, a second flaky molded material outer layer and a prepreg layer arranged between the first flaky molded material outer layer and the second flaky molded material outer layer. While the flaky molded material-prepreg mixed composite material is embedded into a complex component, the warping of a product is prevented, the surface smoothness is maintained, and the thickness of the product can be effectively reduced in the allowable value range of the rigidness so as to realize the light weight; and moreover, when the collision occurs, the splashing can be effectively prevented, and the secondary damage is avoided.

Description

technical field [0001] The invention relates to a sheet molding material-prepreg hybrid composite material and a manufacturing method thereof, belonging to the technical field of composite materials. Background technique [0002] Sheet Molding Compound (SMC) is a resin paste mixed with resin, thickener, initiator, crosslinking agent, low shrinkage additive, filler, internal release agent and colorant, and then impregnated with chopped fiber roving or It is formed by covering the upper and lower sides with polyethylene or polypropylene film. Because SMC has the advantages of superior electrical properties, corrosion resistance, light weight, easy engineering design, and flexible manufacturing, its mechanical properties can be compared with some metal materials, so it is widely used in transportation vehicles, construction, electronics / electrical industries, etc. . [0003] Prepreg is a resin matrix impregnated with continuous fibers or fabrics under strictly controlled cond...
