Abstract

The utility model relates to a cabin cover before continuous carbon -fibre composite car is particularly useful for the new forms of energy electricelectric and moves medium -to -high grade car. The cabin cover comprises planking and inner panel before the car, and the inner panel and the planking of cabin cover is continuous carbon fabric preimpregnation material compression molding respectively before the car, and inner panel and planking splice the assembly assembly. Comparing with metal vehicle body, satisfying under service conditions's the circumstances, the cabin cover has the obvious heavy advantage that subtracts before the carbon -fibre composite, can subtract heavyly more than 60%, still has excellent corrosion -resistant, thermal -insulated and noise reduction performance. Owing to adopted new material and new technology, the weight loss can reduce the car energy resource consumption, provides new technical means for realizing vehicle lightweight, volume production efficiency.

Description

A kind of continuous carbon fibre composite material car nose cabin lid

Technical field

A kind of continuous carbon fibre composite material front hatch cover that this utility model relates to, it is adaptable to car, is particularly suited for the pure electronic medium-to-high grade car of new forms of energy.

Background technology

Current car nose cabin lid is generally made up by metal plate punching and welding procedure of the metal material such as steel plate or aluminium alloy plate. Steel front hatch cover has the shortcomings such as big, the poor corrosion resistance of own wt; It is inconspicuous that aluminium alloy front hatch cover has technique weight loss effect, high in cost of production shortcoming; Metal front hatch cover has that weight is big and the shortcoming such as parts are many on the whole.

Summary of the invention

The purpose of this utility model is: provide a kind of lightweight continuous carbon fibre composite material car nose cabin lid.

The technical solution of the utility model is: car nose cabin lid is made up of outside plate and inner panel, and the inner panel of car nose cabin lid and outside plate are the compression molding respectively of continuous carbon fibre Fabric prereg, inner panel and outside plate and glued joint assembly.

The material matrix that inner panel and outside plate adopt is epoxy resin or modified epoxy or bismaleimide resin.

The carbon fiber that inner panel or outside plate adopt is one or both of the continuous fiber of T300 level and T700 level.

The carbon fiber that inner panel or outside plate adopt be 3K, 12K, many kinds of tow of 24K, 48K and 50K therein one or more.

The connection adnexa of car nose cabin lid and vehicle body is glued on inner panel.

The utility model has the advantages that: this front hatch cover is made up as the composite of reinforcement of continuous carbon fibre and fabric thereof, the material of lightweight makes product weight decline by a relatively large margin, plus the excellent corrosion resistance of matrix, fatigue durability and noise abatement heat-proof quality, can be used for replacing existing metal front hatch cover, reduce the energy resource consumption of automobile.

The front hatch cover adopting continuous carbon fibre and fabric thereof to make as the composite of reinforcement, compares steel body weight and reduces more than 60%, has corrosion-resistant, endurance, noise reduction and the advantage such as heat insulation simultaneously.

Accompanying drawing explanation

Fig. 1 is carbon fibre composite car nose cabin lid schematic diagram.

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further illustrated.

Car nose cabin lid is made up of outside plate 1 and inner panel 2, and the inner panel 2 of car nose cabin lid and outside plate 1 are the compression molding respectively of continuous carbon fibre Fabric prereg, and inner panel 2 and outside plate 1 glued joint assembly.

Front hatch cover adopts inner and outer plates combinative structure, and its inner and outer plates all adopts continuous carbon fibre/thermosetting resin prepreg (CFRP) mould pressing process manufacture, and vehicle body connects adnexa and is glued on inner panel, and inner and outer plates glueds joint assembly.

This car nose cabin lid mainly includes inner panel, outside plate and adnexa, and its manufacture process and method are as follows:

1) inner panel 2 and outside plate 1: laminate structure, adopts mould pressing process molding, and material is " continuous carbon fibre woven cloth prepreg ";

2) adnexa is connected: after laminate molding, nut slave board 3 and nut slave board 4 locating glue are connected on inner panel 2;

3) assembling: inner and outer plates adopts periphery fit and glued joint molding, is assembled into " outside plate+structure glue+inner panel ".
