Technical field
The present invention relates to arrangements for automotive doors structure field, be specifically related to a kind of composite structure door anti-collision joist and manufacturer thereof
Method.
Background technology
Door anti-collision joist is parts the most crucial in vehicle passive safety field.Automobile side is intensity in car body
Weaker part.Car is in the case of side impact, only across car door 20-30 li between passenger and the collision thing strongly run through
The distance of rice, thus, the injury of occupant be may often be such that fatal by side collision sometimes.Just because of this, sedan door inner and outer plates it
Between be typically provided with collision prevention girders, car door is reinforced.
Generally, the one or two firm girder steel of side door interlayer intermediate arrangement at automobile constitutes side door collision prevention girders, and side door is crashproof
Beam usually uses high-strength steel material molding.Crashproof beam action is as follows: when side door is clashed into, and firm collision prevention girders can be significantly
Alleviate the deformation extent of side door, thus reduce the automobile impacting injury to passenger.Therefore, the intensity of door anti-collision joist itself
It is parts the most crucial during automobile side collides with rigidity.
Numerous known, automotive light weight technology design and manufacture are the targets that current automotive industry is seek assiduously.As being peace
Full part is also the automobile front and back door of covering, and strict its construction weight that controls can also improve car door pendency problem.But, for
Security consideration, existing door anti-collision joist so that car door is heavier, under meeting security requirement, it is impossible to meet car door light
Quantify requirement.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that safety guarantor can be provided when automobile side collides
Protect, it is ensured that safety, composite structure door anti-collision joist and the manufacture method thereof of car door lightweight requirements can be met again.
To achieve these goals, the technical solution used in the present invention is:
This kind of composite structure door anti-collision joist, including collision prevention girders outside plate, is provided with composite wood in the middle part of described collision prevention girders outside plate
Material inner panel.

The ply stacking-sequence of described carbon fiber prepreg is [90/0/90/0] S.
Described collision prevention girders outside plate and reinforcing plate for automobile door hinge welding.
The manufacture method of the composite structure door anti-collision joist of this kind, particularly as follows:
(1) door anti-collision joist outside plate is made；
(2) collision prevention girders outside plate middle part surface is carried out oil removing cleaning；
(3) choosing carbon fiber prepreg is raw material, according to the performance requirement of door anti-collision joist, determines composite inner panel
The laying number of plies and order, carry out notch cuttype laying by carbon fiber prepreg；
(4) put in the middle part of door anti-collision joist outside plate in composite material moulded former, and position；Then step (3) is obtained
To carbon fiber prepreg laying be positioned on door anti-collision joist outside plate；
(5) use composite material moulded former and mold formpiston, by molding former and molding the pressure of formpiston, at high temperature
Make collision prevention girders outside plate and carbon fiber prepreg laying curing molding under high pressure, complete composite inner panel and the glue of collision prevention girders outside plate
Connect, make composite structure door anti-collision joist.
In described step (2), use acetone solvent that door anti-collision joist outside plate middle part surface is carried out oil removing cleaning；Described step
Suddenly, in (3), carbon fiber prepreg ply stacking-sequence is [90/0/90/0]S。
In described step (3), when carbon fiber prepreg carries out notch cuttype laying, carbon fiber prepreg adjacent layer is on both sides
The width staggered is 25.4mm.
In described step (5), mold former be provided with collision prevention girders outside plate in the middle part of adaptive groove, mold formpiston and be provided with
The pressure head adaptive with molding former upper groove.
It is an advantage of the current invention that: the present invention is the most too much increasing car door weight, meets under car door lightweight requirements, it is ensured that
While improving car door anti-collision beam strength, use composite that high-strength steel part is strengthened, collision prevention girders is significantly increased
