another kind of forming method is primary and secondary vacuum bag molding: be filled in the inner chamber formed between truss members and wallboard by the cylindricality vacuum bag of prefabricated, similar tubular, cover outer vacuum bag at the outer surface of Ω type reinforcement and wallboard upper berth, another space between the inner surface of the space between cylindricality vacuum bag outer surface and the inner surface of Ω type reinforcement and outer vacuum bag and the outer surface of Ω type reinforcement, wallboard is connected and seals; The advantage of the method is: reduce shaping cost.But require high for the level of skill of operator, once vacuum bag gas leakage, be easy to cause scrapping of part.
summary of the invention:
the object of this invention is to provide a kind of reinforcement wallboard co-curing forming method.
above-mentioned object is realized by following technical scheme:
a kind of reinforcement wallboard co-curing forming method, its method comprises the following steps:
(1) truss members preformed;
(2) paving of wall panel skin;
(3) location, position of truss members;
(4) co-curing.
described a kind of reinforcement wallboard co-curing forming method, described step (1) truss members preformed:
first, truss members preforming tool adopts the mode of brush coating and manual paving, first by preforming tool position, truss members is carried out bending; After completing, paste vacuum bag, vacuumize around the truss members after bending, vacuum is greater than 0.07 Mpa; Preformed is carried out in curing oven; Preformed temperature 80 ± 5 DEG C, constant temperature 1 hour, heating rate is 2 ~ 5 DEG C/min.
described a kind of reinforcement wallboard co-curing forming method, the paving of described step (2) wall panel skin: according to design drawing requirement, is successively laid on mould (or platform) with order by the laying direction of regulation.
described a kind of reinforcement wallboard co-curing forming method, the location, position of described step (3) truss members: the truss members place preformed on demand in the covering forming frock putting covering well after and various keeper, and the position of the truss members after each preformed and various keeper is determined by laser-projector, the inside of truss members adopts hard silicon rubber core as support, ensures truss members profile in the process of co-curing.Use location silicon rubber to prevent truss members in co-curing process from producing displacement in truss members outside simultaneously.
described a kind of reinforcement wallboard co-curing forming method, described step (4) co-curing: paste vacuum bag around the truss members after determining position by laser-projector and various keeper, be cured in curing oven, solidification temperature is 180 ± 5 DEG C, temperature retention time is 150+10 min, pressure is 0.4 ~ 0.6MPa, temperature rate 1 ~ 3 DEG C/min.
beneficial effect of the present invention:
1. the present invention is directed to the deficiency that exists in conventional art and design and provide a kind of forming method for truss members wallboard co-curing, reduce frock cost, simplify forming operation operation.
the present invention adopts the mode of composite material skin and truss members co-curing, greatly reduces the quantity of connector, decreases assembly work amount, decreases stress simultaneously and concentrates and the weakening of rivet hole to wallboard cross section, alleviate the weight of connector itself; In addition, co-curing does not need the coordination between load module; The structural integrity of co-curing component is good.
