Problems solved by technology

[0004] However, the existing technology cannot make the resin powder evenly distributed on the surface of the reinforced continuous fiber, and the adsorption amount of the resin powder is limited and difficult to adjust, so that the obtained thermoplastic unidirectional tape has uneven weight, easy warping, and the adjustment range of the fiber content is small, which is limited. Production of thermoplastic unidirectional tapes

Abstract

The invention discloses a thermoplastic one-way belt production device and method. The thermoplastic one-way belt production device includes a yarn creel, a yarn spreading device, a powder spreading device, a heating device, a press-fit device, a cutting device, a winding part and a supporting roller way; the supporting roller way is arranged between the yarn spreading device and the winding part,and the two ends of reinforced continuous fiber are arranged on the yarn creel and the winding part respectively; in the direction from the yarn creel to the winding part, the powder spreading device, the heating device, the press-fit device and the cutting device are sequentially arranged on the supporting roller way; and the powder spreading device comprises a plurality of powder spreading machine heads, wherein the powder spreading machine heads are correspondingly arranged on the right side and / or the left side of the yarn spreading device. According to the thermoplastic one-way belt production device and method, the powder spreading device is arranged so that the fiber content in a thermoplastic one-way belt can be adjusted within a relatively large adjusting range, moreover, resin powder is uniformly dispersed, the powder distribution amount can be adjusted on the surface of the reinforced continuous fiber, so that the thermoplastic one-way belt is not prone to warp.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a thermoplastic unidirectional belt production equipment and method. Background technique [0002] With the development of fiber-reinforced thermoplastic composites, continuous fiber-reinforced composites have been used more and more in practical applications due to their advantages of high strength and light weight compared with other composite materials. [0003] The existing thermoplastic unidirectional belt impregnation equipment and methods are mainly three types: the first is the laminating method, and the reinforced continuous fiber is spread and clamped between two plastic melt films extruded by the extruder. In the middle, impregnate and cool through several pairs of rollers, and finally wind up to obtain a sheet; the second method is the powder impregnation method, which spreads the reinforced continuous fiber and passes through a hopper filled with plastic powder to ...
