Description

technical field [0001] The invention relates to a device and a method for treating the surface of materials with atmospheric pressure gas discharge plasma. Background technique [0002] High-performance organic fibers have excellent properties such as high strength, high modulus, high elasticity and heat resistance, and have broad application prospects as reinforcing fiber materials in composite materials. However, due to the lack of polar functional groups on the surface of these fiber materials, the gap between The adhesion performance is poor, so it is necessary to modify its surface to improve the adhesion performance between the interface with the base material. There are many treatment methods currently used. Among them, the use of gas discharge plasma to treat the surface of polymer fiber materials instead of traditional chemical methods has the significance of energy saving and environmental protection.

Problems solved by technology

Atmospheric pressure plasma jet technology can also be used to treat the surface of fiber materials. The following problems exist in large-scale processing: 1) Atmospheric plasma jet temperature is high, and the ablation effect on the fiber surface reduces the mechanical strength of the fiber. Using discharge auxiliary gas energy Reduce the processing temperature, but to ensure that the jet has a sufficient range, high-flow gas is required, which increases the consumption of gas; 2) The plasma jet surface has a different effect on the surface facing and facing away from the fiber, which affects the uniformity of the treatment, thus Affects the adhesion between fiber and matrix material in composite materials
