Problems solved by technology

[0004] At present, in the process of melt impregnating thermoplastic composite materials, a relatively complex impregnation die is generally used, and the fiber and resin are impregnated at the die, such as US patent US5037284, US4588538, etc. This special die can be fiber and resin The impregnation effect is greatly improved, but the design cost of the die head is high. In addition, the impregnation process is carried out inside the die head. The specific process of impregnation is difficult to control, and if the yarn breaks, it is quite inconvenient to re-draw the yarn. Seriously affect production efficiency

Embodiment 2

[0040] A device for making continuous fiber fabric reinforced thermoplastic resin, the device includes an unwinding component, a tension control component, a static elimination and preheating component, an impregnating component, a cooling component and a winding component arranged in sequence.

[0041] Wherein, the unwinding assembly is composed of a creel, on which the continuous fiber fabric with a fixed width is statically placed. Tension control component: It is composed of three tension rollers evenly arranged according to the positions of the three vertices of an equilateral triangle. The tension rollers can not only increase the tension of the continuous fiber reinforced fabric during the reproduction process, but also allow it to be evenly arranged in parallel to reduce fiber filaments Horizontal gaps between the bundles (continuous fiber tows) and making the surface of the fiber fabric smoother and flatter help avoid fluffing during the impregnation process and avoid ...

Abstract

The invention relates to equipment used for preparing a continuous fabric reinforced thermoplastic resin. The equipment comprises an unreeling assembly, a tension control assembly, a destaticizing and preheating assembly, a dipping assembly, a cooling assembly and a reeling assembly which are arranged successively. Compared with existing technology, a double-belt roller press is adopted for dipping of fiber and resin, so that defects of thermoplastic materials, such as high melt viscosity and poor melt fluidity, are avoided. In addition, different form pultrusion processes, the reinforced thermoplastic resin with high glass fiber content can be prepared without using any mould. The equipment is simple; operation is easy, fiber content is high, and complete infiltration of fiber and resin can be ensured.

Description

technical field [0001] The invention relates to the field of polymer composite material equipment, in particular to an equipment for making continuous fiber fabric reinforced thermoplastic resin. Background technique [0002] Fiber-reinforced thermoplastic composites have excellent properties, high mechanical strength, reusability, light weight, excellent impact resistance, and excellent environmental protection. They have been more and more used in daily life in recent years. There are many studies on chopped fiber reinforced thermoplastic composites, such as patent US3684645, which uses chopped fiber and thermoplastic resin to check and enter a double-belt vulcanizer, heat impregnation, and cut into required sheets. [0003] The high melt viscosity of thermoplastic resin is one of the most critical factors limiting its development. The high viscosity of the melt causes some adverse effects when it is combined with the fiber. For example, the impregnation effect of the fib...
