Abstract
The invention discloses a carbon fiber prepreg for a large vacuum-formed product. The carbon fiber prepreg comprises a one-way carbon fiber prepreg layer and a sheet-shaped or net-shaped fiber base material layer; one side of the one-way carbon fiber prepreg layer is completely soaked by matrix resin; the other side of the one-way carbon fiber prepreg layer is not completely soaked by the matrix resin; the sheet-shaped or net-shaped fiber base material layer is covered at one side, which is not completely soaked by the matrix resin, of the one-way carbon fiber prepreg layer; and the carbon fibers in the sheet-shaped or net-shaped fiber base material layer are unordered net-shaped carbon fiber meshes. According to the invention, the problems of high radial strength and low latitudinal strength of the one-way carbon fiber prepreg are solved; in a vacuum forming process, the carbon fiber prepreg is loose and is not adhered together; the carbon fiber texture of the loose part can be used as a gas guide channel to facilitate discharge of gas, and the problem that the carbon fiber prepreg is prematurely adhered so that the gas can not be discharged, and gaps are formed can be avoided.
Description
Technical field
The present invention relates to technical field of polymer materials, particularly a kind of vacuum forming massive article is used carbon fiber prepreg.
Background technology
Continuous and the tight demand of socio-economic development along with the science hormonal readiness; Carbon fiber is shown great attention to by countries in the world with its high specific strength, high ratio modulus, corrosion-resistant, antifatigue, light weight, conduction, a series of comprehensive excellent properties such as heat insulation, high temperature resistant; Carbon fiber has been widely used in Aeronautics and Astronautics, vehicle manufacturing, naval vessel industry, field of wind power generation
At present, the consumption of carbon fiber more than 70% all is that application mode through carbon fiber prepreg realizes.In order to give full play to the superhigh intensity property of carbon fiber, all be that the prepreg that carbon fiber is made the single line fiber is made various products.And this prepreg that has only radial fiber not have weft fiber has a lot of defectives: 1, radial strength is high, latitudinal strength is low.Breadth splits easily when 2, using, and operating portion is convenient.3, be prone to hidden danger of quality such as wrinkle, slit behind the layer of shop.3, in the manufacturing of preparation large-scale composite material goods, because the length of goods is thicker, when using the moulding of common carbon fibers prepreg; Can not be together sturdy closely between each layer of prepreg, it is residual to have a spot of air, and does not have the passage of exhaust at interlayer; It can not in time be drained when vacuumizing; The carbon fiber prepreg of multilayer shop is covered like this, and residual air can build up to increase and form big space, causes in the goods and can form the space; Carbon fiber is bent, thereby have a strong impact on the mechanical performance of goods.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of vacuum forming massive article to use carbon fiber prepreg to the existing existing deficiency of carbon fiber prepreg.
Technical problem to be solved by this invention can realize through following technical scheme:
The vacuum forming massive article is used carbon fiber prepreg; It is characterized in that; Comprise the unidirectional carbon fiber dimension preimpregnation bed of material and sheet or reticular fibre substrate layer; Prepreg is laminated is soaked into fully by matrix resin for said unidirectional carbon fiber dimension, and another side is not soaked into by matrix resin fully, and wherein sheet or reticular fibre substrate layer cover on the one side that the said unidirectional carbon fiber dimension preimpregnation bed of material do not soak into by matrix resin fully; Carbon fiber in said sheet or the reticular fibre substrate layer is netted unordered carbon fibre web sheet.
The invention has the beneficial effects as follows: the present invention has changed the problem that unidirectional carbon fiber dimension prepreg radial strength is high, latitudinal strength is low.Simultaneously because the laminated structure of carbon fiber prepreg is closely knit; The one side structure is loose relatively; And sheet or reticular fibre substrate layer are covered on the one side that the said carbon fibre initial rinse bed of material do not soak into by matrix resin fully; Like this in the vacuum forming process; Each other oneself is looser almost is not bonded together for carbon fiber prepreg, and the carbon fiber tissue of loose part can help the discharge of gas as air guide channel, avoids the too early bonding gas that causes of carbon fiber prepreg can't discharge and the generation of interstitial problem.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Further describe the present invention below in conjunction with the accompanying drawing and the specific embodiment.
Referring to Fig. 1; The vacuum forming massive article that provides among the figure is used carbon fiber prepreg; Comprise the unidirectional carbon fiber dimension preimpregnation bed of material 10 and sheet or reticular fibre substrate layer 20; The unidirectional carbon fiber dimension preimpregnation bed of material 10 one sides are soaked into by matrix resin fully, and another side is not soaked into by matrix resin fully, and wherein sheet or reticular fibre substrate layer 20 cover on the one side that the unidirectional carbon fiber dimension preimpregnation bed of material do not soak into by matrix resin fully; Carbon fiber in sheet or the reticular fibre substrate layer 10 is netted unordered carbon fibre web sheet.
