Abstract
The invention relates to the field of composite material processing technology, in particular to a construction structure and a method for improving the rich resin of a complex profile of a composite material web plate.
Description
Technical Field
The invention relates to the field of composite material processing technology, in particular to a construction structure and a method for improving the complex profile of a composite material web plate to be rich in resin.
Background
In the process of preparing composite material products such as wind power blade webs and the like by adopting a vacuum infusion process, for example, complicated molded surfaces such as web bonding surface corners and the like can cause the problem of resin enrichment of the products due to the fact that auxiliary materials cannot be attached to a mold, and the finished product resin enrichment polishing in subsequent procedures can also cause secondary damage of the products.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a construction structure and a method for improving the complex profile of a composite web plate and enriching resin.
The invention is realized by the following technical scheme:
a construction structure for improving the complex surface resin-rich of a composite web is characterized by comprising: the web mould, locate the web body in the web mould, cover the vacuum bag membrane on the web body and locate the pouring between web body and the vacuum bag membrane and assist the material, be located the easy rich resin region top of web body pour into assist the material and be equipped with high temperature resistant layer between the vacuum bag membrane, high temperature resistant layer and web mould closely laminate.
Preferably, the high temperature resistant layer is made of high temperature resistant silica gel, PET or PVC material.
Preferably, the pouring auxiliary material comprises a flow guide net, a separation film with holes and demolding cloth.
A construction method for improving the complex profile of a composite web plate to be rich in resin is characterized by comprising the following steps:
a. paving a finished web plate body in the web plate mould, and paving a pouring auxiliary material on the web plate body;
b. paving a high-temperature-resistant layer in the area of the web body easy to be rich in resin, wherein one side of the high-temperature-resistant layer is tightly attached to the web mold;
c. and laying a vacuum bag film, and curing the web body.
The invention has the beneficial effects that:
the high-temperature-resistant layer is attached to the surface of the pouring auxiliary material, so that appropriate stress can be provided, the pouring auxiliary material is tightly attached to the mold, and the problem that the complex molded surface is rich in resin is effectively improved or even eliminated;
the time for cleaning the resin-rich product after demoulding is shortened, and the risk of secondary damage caused by subsequent process treatment is eliminated;
extra conditions and waiting time do not need to be set, the materials are simple and easy to obtain, and the material can be designed according to different requirements and can be repeatedly used, so that the cost is reduced;
no secondary pollution is brought to the product body.
Drawings
Fig. 1 is a schematic front view of the present invention.
In the figure: 1. the high-temperature-resistant layer, 2, the web body, 3, the pouring auxiliary material, 4, the vacuum bag film and 5, the web mold.
Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the web plate body 2 is paved according to the technical requirements, after the pouring auxiliary material 3 is paved on the web plate body, before the vacuum bag film 4 is paved, the high-temperature resistant material is paved to be tightly attached to the web plate mold 5 corresponding to the easy resin-rich area of the web plate body to form the high-temperature resistant layer 1, one side of the high-temperature resistant layer is tightly attached to the easy resin-rich area, the other side of the high-temperature resistant layer can be designed into different shapes according to requirements to ensure the force application direction of the high-temperature resistant layer, simultaneously, the resin-rich condition of the high-temperature resistant layer and the corner area of the web plate body is weakened or even eliminated, finally, the vacuum bag film is paved, after the product is solidified, the high-temperature resistant layer is demoulded by a physical method, the high-temperature resistant layer can.
Because the effect of high temperature resistant layer is for giving the supplementary material pressure of pouring, makes the supplementary material of pouring hug closely web body and web mould, prevents to pour and forms the cavity between supplementary material and the web mould to eliminate the rich resin defect that the glue solution enrichment formed in the process of pouring, increase follow-up drawing of patterns efficiency and web bonding quality.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
