Embodiment Construction

[0015] The technical solution of the present invention will be described in detail below.

[0016] The manufacturing process of composite felt fabric among the present invention comprises the following steps:

[0017] (1) Prepare the mold

[0018] High-quality molds are also a must for the manufacturing process. Specifically, the surface of the mold should have high hardness and high gloss, and at least 15 cm should be reserved on the edge of the mold to facilitate the laying of sealing strips and pipelines.

[0019] Preparing the mold includes cleaning the mold, and then removing the mold release wax or wiping the mold release water and other sub-steps.

[0020] (2) Carry out gel coat surface construction

[0021] According to the requirements of the product, product gel coat and sanding gel coat can be carried out, and the optional gel coat materials are ortho-, m-, and / or vinyl. The construction of the gel coat surface adopts the methods of hand brushing and spraying. ...

Abstract

The invention relates to a composite felt-type fabric manufacture process. The composite felt-type fabric manufacture process comprises the following steps: (1) preparing a die; (2) carrying out gel coat construction on the surface of the die; (3) laying a reinforcing material; (4) laying vacuum bag materials according to the laying sequence of an upper demoulding cloth, a guide cloth and a vacuum bag; (5) evacuating the system constructed by the step (4) after the materials of the step (4) are laid; (6) preparing resin after the evacuation operation meets a certain requirement; (7) feeding the resin prepared in the step (6) to the system processed by the step (5); and (8) demoulding. The manufacture process can be used for manufacturing products with lighter weight and higher strength at a higher accuracy and a higher speed. In addition, the manufacture process ensures that the technique cost and the material cost during batch production are lowered.

Description

technical field [0001] The invention relates to a manufacturing process, in particular to a manufacturing process of a composite felt fabric. Background technique [0002] In the prior art, each manufacturer mainly uses glass fiber biaxial fabrics, in order to achieve a uniform thickness of 7.5-8mm after forming the product. It takes more than 6 hours to lay up layers for each production, because ordinary 0 / 90 Or the thickness of similar biaxial woven fabric is 0.6-0.8mm per layer, and each part needs to be repeated 8-10 times per square meter. The upfront time consumed by the entire molding process accounts for 70%. When making large parts, this method in the prior art has the disadvantages of consuming a lot of manpower and inputting a lot of auxiliary materials. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process for composite felt fabrics capable of producing lightweight and high-strength composite felt fabrics...
