Abstract

The invention provides a manufacturing method of a component with vacuum stiffener structure by vacuum guiding. The method comprises the following steps of: (1) preparing a mould, cleaning out the surface of the mould, and then spraying a mold release agent for at least one time and drying the mould release agent completely; (2) laying a reinforced material layer on the mould which is processed by step (1) according to required size and the thickness of the layer; (3) placing the stiffener on the reinforced material layer; and (4) laying demoulding cloth and high permeable medium on the layers of the stiffener and the reinforced material and laying out an inlet and an outlet for resin. The method is characterized in that a balloon is put into the stiffener in the step (3) and the balloon is filled with air. The method has the advantages that the function and integrity of ships, large components of locomotives and vehicles, or an enginery room cover are improved, the manufacture cycle of a product is shortened, and the manufacture cost is reduced.

Description

A kind of vacuum introduction manufacture method with the vacuum reinforced rib structure member
Technical field
The present invention relates to a kind of vacuum introduction manufacture method, be applicable to the band reinforcing rib structure with the vacuum reinforced rib structure member, as: the vacuum of engine room cover, boats and ships, locomotive and vehicle imports manufacturing process, belongs to resin vacuum guiding and forming technique technical field.
Background technology
The vacuum resin vacuum guiding and forming technique because have that the properties of product that make are good, steady quality, advantage such as environmental pollution is little and working condition is good, in the manufacturing of the large component of boats and ships, locomotive and vehicle or engine room cover, substitute hand rapidly and stick with paste technology, occupy tangible technical advantage.But,, usually adopt reinforcing rib structure in order to strengthen the rigidity of structure along with the expansion of these large component sizes.At present, be mostly: stick with paste technology with hand earlier and in small mould, make reinforcing rib structure, after the large component main structure is finished the manufacturing of vacuum introducing technology, stick with paste technology with hand again and be connected on the main structure then in the method that connects these reinforcing rib structures on the large component.This method has not only prolonged the manufacturing cycle of product, has increased labor cost, and has influenced work situation.
If can directly when main structure is carried out the vacuum introducing technology, reinforcement be finished simultaneously together, so not only improve the globality and the properties of product of structure, and shortened the manufacturing cycle greatly, reduce manufacturing cost and improved work situation.But problem is a reinforcement is hollow, if make together with main structure, a large amount of resins is entered in the hollow-core construction of reinforcement, so not only increased the weight of product greatly, wasted a large amount of resins, improved manufacturing cost, and product properties also can descend.Once adopted the confined air core structure of rigidity, can be directly on the principle and main structure finish the vacuum introducing technology together.But when practical operation, there are a lot of problems: if at first adopt fiberglass to make closed structure, because in manufacture process, closed structure inside is an atmospheric pressure, and structure is close to vacuum outward, closed structure is subjected to very big pressure from inside to outside, usually, cause leaking, and make the technology failure at the weakness of structure; If adopt the aluminium alloy structure of welding, then improved manufacturing cost greatly.
Summary of the invention
The purpose of this invention is to provide a kind of when main structure is carried out the vacuum introducing technology, the vacuum introduction manufacture method that reinforcement is finished simultaneously together.
In order to achieve the above object, technical scheme of the present invention has provided a kind of vacuum introduction manufacture method with the vacuum reinforced rib structure member, the steps include:
Step 1, preparation mould are cleaned out die surface, and at least releasing agent of spraying also dries fully subsequently;
Step 2, reinforcing material shop layer size and shop layer thickness in accordance with regulations is laid on the mould of handling well by step 1;
Step 3, on reinforcing material shop layer, place reinforcement;
Step 4, on the layer of reinforcement and reinforcing material shop lay release cloth and high permeable medium, and the import and the outlet of laying resin as required;
Step 5, coat with vacuum bag, and around the sealing, last resin is gone into by import, unnecessary resin is by exporting out;
It is characterized in that, in the described reinforcement of step 3, put into balloon, and in described balloon, be filled with air.
Further, balloon adopts corrosion-resistant and heat-resisting good elastomeric material to make; Described elastomeric material can be chemicals or corrosion-resistant and heat-resisting good rubber such as anti-styrene.
Before the vacuum introducing technology begins, balloon and the reinforcement inwall of getting along well contact.But when technology was carried out, along with the gas in the vacuum bag is constantly taken out, the vacuum in the reinforcement also progressively improved, and balloon just begins to expand, and fitted with the inwall of reinforcement.At this moment the pressure in the balloon greater than vacuum less than atmospheric pressure.Because the balloon internal pressure is greater than vacuum, so resin can not enter the inside of reinforcement when technology is carried out.And since the balloon internal pressure much smaller than atmospheric pressure, so also can reinforcement jack-up not come, thereby technology is carried out smoothly.After technology finished, balloon was just stayed in the reinforcement, can not have influence on the performance of reinforcement.Because its air pressure is very little, is lower than an atmospheric pressure, if wish that the reinforcement external and internal pressure is identical, can make a call to a hole on reinforcement.Advantage of the present invention is: improved the large component of boats and ships, locomotive and vehicle or the performance and the globality of engine room cover, shortened the product manufacturing cycle, reduced manufacturing cost.
