Embodiment 1

[0048] Step 1. Pretreatment of the fiber surface: Soak the single-layer carbon fiber cloth 1 with a thickness of 0.111 mm in acetone for 24 hours, then wash it repeatedly with deionized water and dry it for later use to remove the organic glue and impurities on the surface of the carbon fiber. The carbon fiber cloth 1 and the single-layer glass fiber cloth 2 with a thickness of 0.2 mm are immersed in a hydrofluoric acid solution with a concentration of 25% for 30 seconds to roughen the fiber surface;

[0049] Step 2, preparation of impregnation solution: the concentration of epoxy resin in the impregnation solution is 56wt%, the concentration of ethanol is 40wt%, the addition of silicon dioxide is 2wt%, and the addition of carbon nanofiber is 2wt%. Stir evenly to obtain resin impregnated The liquid is ready for use; the particle size of the silica is 2 microns.

Abstract

The invention relates to a fiber composite material stem, a preparation method of the fiber composite material stem and an application, and mainly relates to a composite material stem containing a carbon fiber cloth and a glass fiber cloth, a preparation method and an application. The preparation method includes the first step of pretreatment of fiber surface; the second step of preparation of impregnation liquid; the third step of stacking and impregnation of fiber cloth; the fourth step of rolling of fiber cloth; the fifth step of solidifying and demolding; the sixth step of preparation of the i rod; the seventh step of connection; through the seven steps, a complete composite stem can be obtained. The production technique is simple and easy to control; the prepared stem has excellent physical performance and environment corrosive resistance; meanwhile, the stem mass is greatly lightened, thus the transportation, installation and maintenance and repair in later period are more convenient and the cost is reduced; the invention can be applied to light pole, telegraph pole, advertising board stem, civil buildings and the like.

Description

technical field [0001] The invention relates to a fiber composite material rod and its preparation method and application, and mainly relates to a composite material rod containing a carbon fiber cloth and a glass fiber cloth as well as its preparation method and application. Background technique [0002] With the development of municipal construction, municipal facilities have also been better developed. For street lights, it has developed from the original wooden poles to the commonly used iron light poles, stainless steel light poles and aluminum alloy light poles. Although the early wooden poles were light, they are no longer used because they are not resistant to corrosive environments and have low strength. Metal rods are widely used now, mainly because of their rich raw materials, simple preparation process and moderate price. However, there are still some problems in practical application of metal rods, such as heavy weight and poor environmental corrosion resistanc...
