Abstract

The utility model relates to a composite plate for automobile outer shells. The utility model has a two-layer composite structure including one internal layer and one external layer, which is composed of a surround made of enhanced engineering plastics formed according to a definite shape and an inner lining which is made of enhanced epoxy resin and is compounded at the inner side of the surround. The composite plate for automobile outer shells has the advantages of simple production process, low investment and short period of production, with intensity and smoothness of outer shells conforming to specification and requirement, and has all the advantages of plastic automobile outer shells. Automobiles manufactured with the utility model have reduced cost, which is suitable for the domestic consumption level.

Description

Composite plate for automobile outer shell

The utility model belongs to field of automobile, relates to the structural development of automobile case template.

In vehicle manufacturing industry in the past, automobile case is modal to be by metal sheet stretching, stamping forming single-layer metal thin plate car shell, and it is produced, and investment is huge, manufacturing cost is high, and production cycle is long.Five, the sixties glass-felt plastic automobile case that begins to adopt belongs to the reinforced epoxy tree and refers to material product, owing to placed restrictions on by material behavior, up to the present, main still leaning on by hand operated, and not only can't improve output, the more important thing is that car shell outside face can't reach carefully and neatly done bright and clean requirement.The automobile case of the nearest employing injection mo(u)lding that occurs, though its performance can reach designing requirement, and any surface finish, but the making of injection mould is higher than the requirement of metal stamping mould, invests greatlyyer, and the process-cycle is longer, large-scale injection-moulding device is mainly by import, cost an arm and a leg, so, generally be commonly used in the manufacturing of car front and back bumper/spoiler, vehicle body both sides guard strip at present.

The purpose of this utility model is to overcome the defective that exists in the prior art, absorbs its advantage, and the change single layer structure is compound double-decker, and a kind of reduced investment, automobile case template that cost is low are provided.

Described a kind of automobile hood composite plate has compound double-layer structure, promptly is made up of with the reinforced epoxy inside liner that is compounded in the surrounding layer inboard the enhancement engineering plastics surrounding layer of shape moulding on request.During manufacturing, be processed into the enhancement engineering plastic plate earlier, on specialized equipment, carry out the surrounding layer moulding again, at inboard epoxy resin and the reinforcing material composite consolidation of adopting of surrounding layer, form inside liner then.

This automobile hood composite plate, reduced investment, production cycle is short, requirements all up to specification such as intensity, appearance degree of finish, the auto cost of Zhi Zaoing reduces greatly thus, is fit to the domestic consumption level.

Below in conjunction with Figure of description, the utility model is described in further detail, and provide embodiment.

Fig. 1 is automobile hood composite plate local structure enlarged diagrams;

Fig. 2 is an automobile case ceiling template structural representation;

Fig. 3 is an arrangements for automotive doors template structural representation;

According to the different needs and the purposes of automobile, adopt themoplasticity enhancement engineering plastics, as ABS enhancement engineering plastics commonly used, be processed into behind the sheet material by definite shape, dimensional characteristic moulding, make automobile case template surrounding layer (1).Also can adopt thermoset enhancement engineering plastics, be processed into sheet material earlier, sealing, regularly post forming processing.Inside liner (2) adopts the reinforced epoxy material to be compounded in surrounding layer (1) inboard, and surrounding layer (1) and inside liner (2) constitute the two layer composite structure of automobile case template.

The automobile case template of above structure, the production investment of car shell is significantly reduced, have all advantages of plastics car shell again simultaneously, make and omitted expensive and complicated surface of shell treatment process in the car shell production process, the productive costs of car load is further reduced, simplify production technology simultaneously.

Claims

1, a kind of automobile hood composite plate is characterized in that having compound inside and outside double-layer structure, promptly by the enhancement engineering plastics surrounding layer (1) of shape moulding on request be compounded in the inboard reinforced epoxy inside liner (2) of surrounding layer (1) and form.
