Problems solved by technology

[0002] Because Fiber Reinforced Plastic (FRP) has the characteristics of light weight, high mechanical strength and corrosion resistance, it is widely used in various industrial products. Please refer to figure 1 As shown, the fiber composite product is mainly based on polymer resin 1, with woven glass fiber cloth 2 as reinforcement, and uses a composite process similar to reinforced concrete to combine the two to form a structural layer 3, and The surface of the structural layer 3 is coated with paint to form a surface layer 4, which can achieve the effect of beautifying the appearance of the product. However, because the weaving surface of the glass fiber woven cloth 2 is up and down due to the interweaving of fiber bundles, and It is full of weaving pores 5, and the composite resin 1 will shrink in volume during the curing process, which will cause the surface of the structural layer 3 to fluctuate, making the thickness of the surface layer 4 vary, affecting light reflection and causing thread marks. (print-throughphenomenon, PTP) phenomenon, such as figure 2 As shown, it is a schematic diagram of reflection imaging of a daylight lamp group. The phenomenon of

Embodiment Construction

[0023] Please also see image 3 , Figure 4 , Figure 5 as well as Image 6 Shown is a flow chart of a preferred embodiment of the present invention, a perspective view of a non-woven glass fiber cloth, an exploded view and a cross-sectional view of a fiber composite product, which discloses a manufacturing method of a non-woven glass fiber cloth, Contains the following manufacturing steps:

[0024] Fiber unfolding: After a fiber bundle, such as glass fiber bundle or carbon fiber bundle, is exported from a creel, it is flattened by means of rollers to form a fiber bundle 11 with a relatively low TEX number.

[0025] Resin impregnation: arrange multiple flattened fiber bundles 11 in the same direction, and pass through an impregnation tank containing a curing agent 12, wherein the curing agent 12 is made of resin and accelerator, etc., in a ratio of 100 to 1 Formed after mixing in proportion.

[0026] Material leveling process: the flattened fiber bundles 11 are drawn out ...

Abstract

A method for manufacturing non-woven glass fiber cloth, which includes manufacturing steps such as fiber expansion, resin impregnation, fiber smoothing processing, and finished product coiling, and can produce a non-woven glass fiber cloth for application In the production of various fiber composite products, the phenomenon of thread marks on the surface of the fiber composite products can be effectively improved, so that the surface of the surface layer can clearly present a reflection image of an object.
