Problems solved by technology

If the interface properties between the fiber material and the resin in the reinforced resin composite material are poor, the mechanical properties of the composite material will decrease, and the composite material is prone to delamination during use, resulting in damage to the composite material
Most fibers, such as glass fibers and basalt fibers, have smooth surfaces, few active functional groups, low surface energy, surface chemical inertness, and poor wettability with resin matrix
Its composites with resins tend to have a shorter service life

Abstract

The invention provides basalt fiber and glass fiber mixed reinforced resin, as well as a preparation method and application thereof, and relates to the technical field of composite materials. The preparation method comprises the following steps: adding a coupling agent into a graphene oxide solution to treat mixed fiber consisting of basalt fiber and glass fiber, and carrying out the low temperature plasma process to obtain a modified reinforced material; preparing the basalt fiber and glass fiber mixed reinforced resin from the modified reinforced material and nano-zirconia-blended thermosetting resin through a curing molding process. The preparation method is simple in process; a fiber reinforcing body and resin are both subjected to certain modification treatment, so that the reinforced resin is extremely high in consistency; meanwhile, with the excellent characteristics of the basalt fiber and the glass fiber, the reinforced resin is high in mechanical property and corrosion resistance, can be applied to the field of building materials, and has a good development and application prospect.

Description

technical field [0001] The invention relates to the field of composite materials, and in particular to a reinforced resin mixed with basalt fiber and glass fiber and its preparation method and application. Background technique [0002] In the existing field of composite materials, high-performance fibers such as glass fibers and carbon fibers are generally used as reinforcements to prepare composite materials, which are new structural functional materials with the best development prospects at present. However, most high-performance fibers are expensive and are only used in the military field, and only glass fibers are widely used in the civilian field. However, the production process of glass fiber is harmful to the human body, which is not conducive to energy saving and environmental protection. [0003] At present, basalt fiber is more and more popular because of its unique properties and advantages. Basalt is a high-performance volcanic rock component. After melting th...
