Composite fiber preparation method of microwave-assisted diamond-like carbon film covered glass fiber

Abstract

The invention relates to a composite fiber preparation method of microwave-assisted diamond-like carbon film covered glass fibers. The method comprises the following steps of: 1) starting a microwave plastic chemical vapor deposition system and vacuumizing; 2) feeding natural gas into a cylindrical stainless steel vacuum chamber to enable the natural gas to be fully filled in the entire cylindrical stainless steel vacuum chamber; 3) starting a microwave source to enable the microwave source to generate microwaves to excite plasmas in a conical metal roller, so as to fully decompose the natural gas into hydrocarbon groups with activity; 4) adding raw material glass fibers into the conical metal roller; 5) starting a motor to enable the raw materials to be evenly dispersed and centrifugally move, wherein, at the moment, the hydrocarbon groups produced by the decomposed natural gas are deposited on the surfaces of the glass fibers and grow to a diamond-like carbon film, and composite fibers, i.e. the diamond-like carbon film covered glass fibers are formed and are regularly discharged; 6) repeating step 1 to step 5; and 7) after the production is finished, closing all valves and shutting down the microwave and the engine. The composite fiber preparation method of microwave-assisted diamond-like carbon film covered glass fibers provided by the invention has the advantages of low cost, simplicity in implementation and convenience in operation.

Description

technical field [0001] The invention relates to the field of diamond-like film-reinforced composite materials, in particular to a method for preparing composite fibers in which diamond-like film-coated glass fibers are assisted by microwaves. Background technique [0002] As the world's mineral resources are decreasing and the demand for materials in industrial production is increasing, fiber-reinforced composite materials have been widely used in various aspects of production, life, military and national defense due to their significant enhancement effect on the mechanical properties of materials. Wood-plastic composites are popular because of the low price of raw plant fibers, but the main problem to be solved in the production process of wood-plastic composites is to improve the wettability between plant fibers and thermoplastics, so as to strengthen the relationship between plant fibers and the matrix. Bonding properties between plastics. At present, the commonly used c...

Problems solved by technology

At present, the commonly used chemical treatment methods will improve the impact performance and bending performance of plant fiber reinforced composite materials, but in terms of tensile properties, it has dropped a lot due to the weakening of the mechanical strength of the plant fiber itself, which limits its wide application in many fields. At the same time, chemical methods inevitably produce environmental pollution, which is not in line with the concept of social environmental protection development

Therefore, glass fiber, which is cheap compared to carbon fiber, is an inorganic and environmentally friendly material. Glass fiber-plastic composites (glass-plastic composites) have received widespread attention, but glass-plastic composites also need to solve the problem of fiber and plastic. Wettability between interfaces to increase the bonding performance between interfaces
