Abstract

The invention discloses an epoxy-based super-hydrophobic fiber reinforced composite material and a preparing method thereof. The composite material includes a fiber fabric, and a resin and filler part, wherein the resin and filler part includes 100 g of epoxy resin, 220-400 g of polytetrafluoroethylene particles, 242-610 g of an organic solvent, 25-40 g of a curing agent and 3-6 g of carbon nanotubes. The method includes preparing the resin and filter part, preparing a prepreg material and curing the prepreg material to obtain the composite material. The composite material has good super-hydrophobic performance, good wear resistance, good corrosion resistance, good resistance to water flow shock, good adhesive force, high electrical conductivity, and the like, and has high application value and a good application prospect. The method is simple in process and convenient to operate, is suitable for large-scale preparation and facilitates industrial application.

Description

technical field [0001] The invention belongs to the field of preparation of functional composite materials, and relates to fiber-reinforced composite materials and a preparation method thereof, in particular to an epoxy-based superhydrophobic fiber-reinforced composite material and a preparation method thereof. Background technique [0002] The superhydrophobic phenomenon with a contact angle greater than 150° and a rolling angle less than 10° has attracted widespread attention in recent years, and it has strong applications in the fields of self-cleaning, anti-icing, and oil-water separation. And studies have shown that the preparation of superhydrophobic surfaces usually needs to meet two conditions: low surface energy and surface micro-nano secondary structure. [0003] The currently prepared superhydrophobic materials often have types such as coatings, blocks, and fabrics. The coating often encounters cracking and debonding energy problems, which lead to the failure of ...
