High-strength basalt fiber composite bar

Abstract

The invention discloses a high-strength basalt fiber composite bar which is a fiber bar prepared by treating basalt fibers with a surface treating agent, immersing and curing by a matrix resin, wherein the basalt fibers are made of the following components: basalt stone, nano-titanium carbide and ginger-like rock; the matrix resin is prepared from polypropylene resin, vinyl ester resin and rosin. The basalt fiber composite bar according to the invention has strong mechanical properties and can be widely used in industrial and civil construction industries, petroleum industries, aviation industries and the like. The preparation method of the basalt fiber composite bar provided by the invention not only is simple and rapid in step, but also can realize large-scale industrial production, and is low in production cost.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a high-strength basalt fiber composite bar. Background technique [0002] In the existing field of composite materials, the fibers used as composite reinforcement mainly include glass fiber, carbon fiber, boron fiber, alumina fiber, silicon carbide fiber, polyethylene fiber, etc., but due to price constraints, most fibers are only available Used in the military field, only glass fiber is widely used in the civilian field, but in the actual application process, glass fiber still has certain defects as a composite reinforcement, such as: (1) the production process of glass fiber consumes a lot of energy, It is not conducive to energy saving and environmental protection; (2) The preparation process of glass fiber is harmful to the human body, especially the glass fiber wool will have an irritating effect on human skin, and cannot be decomposed or absorbed after being inhaled into ...
