Abstract
The utility model relates to a place apron behind car and use composite sheet, including matrix resin and fibre cloth layer, the matrix resin is as an organic whole with fibre cloth laminating, and the coating has the matrix resin on the fibre cloth layer, fibre cloth layer includes warp direction bundles of glass fibres and latitudinal direction carbon fiber bundle, and warp direction bundles of glass fibres and latitudinal direction carbon fiber bundle intercrossing reticulate, and warp direction bundles of glass fibres and latitudinal direction carbon fiber bundle all have 3000-5000 cellosilk twists to form. The light environmental protection of this film material, can effectively solve existing thermoplastic and incontinuous fiber reinforced composite's the not enough problem of intensity.
Description
Technical field
The utility model belongs to auto parts and components process industry technical field, is specifically related to a kind of automobile rear wall upper cover plate composite sheet.
Background technology
Automobile rear wall upper cover plate is the important component part of automobile, and the inverted draft produced when automobile rear wall upper cover plate Main Function is and lowers running car, increases the downforce of automobile simultaneously.More steady when making running car, thus reduce fuel consumption.Rear deck panel of the prior art, rear deck panel and section bar are linked together by bonded adhesives, and periphery gap-filling glue is filled.Tradition adopts metal, thermosetting fibre reinforced composite or plastics.Metal proportion is comparatively large, and can increase oil consumption, can cause environmental pollution further, light weight material in automobile becomes trend; Thermosetting fibre reinforced composite proportion is 1.8-2.0, due to not recyclable, along with the increase of automobile pollution, and in the long term can to environment; Plastic strength is not enough, yielding, easy fracture.The present invention adopts braided fiber to strengthen thermoplastic composite proportion to be about 1.1, light weight environmental protection, can effectively solve existing thermoplastic and the not enough problem of intensity of discontinuous fiber reinforced composite.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art and provides a kind of automobile rear wall upper cover plate composite sheet, this sheet material light weight environmental protection, can effectively solve existing thermoplastic and the not enough problem of intensity of discontinuous fiber reinforced composite.
In order to achieve the above object, the utility model adopts following technical scheme:
The utility model provides a kind of automobile rear wall upper cover plate composite sheet, and comprise matrix resin and scrim cloth, matrix resin and scrim cloth are integrated, and scrim cloth is coated with matrix resin; Described scrim cloth comprises warp-wise glass fiber bundle and broadwise carbon fiber bundle, and warp-wise glass fiber bundle and broadwise carbon fiber bundle are crossed as netted mutually, and warp-wise glass fiber bundle and broadwise carbon fiber bundle all have 3000 ~ 5000 filament twisteds to form.
According to above-mentioned automobile rear wall upper cover plate composite sheet, also comprise enhancement Layer, enhancement Layer is arranged on the both sides up and down of scrim cloth, enhancement Layer is also coated with matrix resin, described enhancement Layer comprises warp-wise carbon fiber bundle and broadwise glass fiber bundle, warp-wise carbon fiber bundle and broadwise glass fiber bundle are crossed as netted mutually, and warp-wise carbon fiber bundle and broadwise glass fiber bundle all have 3000 ~ 12000 filament twisteds to form.
Described glass fibre filament diameter is 10 ~ 25 μm.
Described carbon fiber wire average fiber footpath is 5 ~ 8 μm, and carbon fiber list beam diameter is 0.3 ~ 0.7mm.
The mesh size of described enhancement Layer is 3 ~ 5 times of the mesh size of scrim cloth.
Described matrix resin is thermoplastic resin.
Described thermoplastic resin is polyethylene, polypropylene, polyvinyl chloride, polystyrene, polymethyl methacrylate, PET or polyformaldehyde.
Compared with prior art, the beneficial effect that obtains of the utility model:
1. the utility model comprises matrix resin and scrim cloth, and matrix resin and scrim cloth are integrated, and scrim cloth is coated with matrix resin; Described scrim cloth comprises warp-wise glass fiber bundle and broadwise carbon fiber bundle, and warp-wise glass fiber bundle and broadwise carbon fiber bundle are crossed as netted mutually, and warp-wise glass fiber bundle and broadwise carbon fiber bundle all have 3000 ~ 5000 filament twisteds to form.Because scrim cloth adopts network structure, the Resisting fractre ability of sheet material can be improved, cover mould good.
2. the utility model structure also comprises enhancement Layer, enhancement Layer is arranged on the both sides up and down of glass layer, described enhancement Layer comprises warp-wise carbon fiber bundle and broadwise glass fiber bundle, warp-wise carbon fiber bundle and broadwise glass fiber bundle are crossed as netted mutually, and warp-wise carbon fiber bundle and broadwise glass fiber bundle all have 3000 ~ 12000 filament twisteds to form.This arrangement enhances the profile pattern that automobile rear wall upper cover plate is shaping, and improve the intensity of whole product.
3. the utility model sheet material can directly use in cutting, and intensity is high and toughness is higher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
With reference to shown in Fig. 1, a kind of automobile rear wall upper cover plate composite sheet, comprise matrix resin 1, scrim cloth 2 and enhancement Layer 3, matrix resin 1 is integrated with scrim cloth is 2-in-1, be provided with enhancement Layer 3 in the both sides up and down of scrim cloth 2, scrim cloth 2 and enhancement Layer 3 are all coated with matrix resin 1; Described scrim cloth 2 comprises warp-wise glass fiber bundle and broadwise carbon fiber bundle, and warp-wise glass fiber bundle and broadwise carbon fiber bundle are crossed as netted mutually, and warp-wise glass fiber bundle and broadwise carbon fiber bundle all have 3000 ~ 5000 filament twisteds to form; Described enhancement Layer 3 comprises warp-wise carbon fiber bundle and broadwise glass fiber bundle, and warp-wise carbon fiber bundle and broadwise glass fiber bundle are crossed as netted mutually, and warp-wise carbon fiber bundle and broadwise glass fiber bundle all have 3000 ~ 12000 filament twisteds to form; Wherein, described glass fibre filament diameter is 10 ~ 25 μm, and carbon fiber wire average fiber footpath is 5 ~ 8 μm, and carbon fiber list beam diameter is 0.3 ~ 0.7mm.
