Abstract

The invention discloses a tapered tube made of glass fiber and carbon fiber hybrid composite materials and a method for manufacturing the tapered tube, and relates to tapered tubes made of glass fiber and carbon fiber hybrid composite materials and methods for manufacturing the tapered tubes. The tapered tube and the method aim to solve problems of excessively heavy structure weights and electromagnetic wave reflection of existing metal, cement or reinforced concrete wire poles, low tensile modulus of single glass fiber composite materials and high prices of single carbon fiber composite materials. The tapered tube is of a three-layer composite structure, an internal through hole of the tapered tube is cylindrical, an inner layer and an outer layer of the tapered tube are glass fiber layers, a middle layer of the tapered tube is a carbon fiber layer, wires are wound in a variable-length and variable-winding-angle manner to form the inner layer, and wires are wound in a full-length and single-winding-angle manner to form the inner layer and the outer layer respectively. The tensile modulus of the obtained tapered tube made of the glass fiber and carbon fiber hybrid composite materials ranges from 16.5GPa to 17.5GPa and is increased by 32-40% as compared with that of a single glass fiber composite material, a forming process is simple and is easy to operate, and the tapered tube and the method are applied to the field of wire poles and lamp poles.

Description

technical field [0001] The invention relates to a tapered pipe made of glass fiber and carbon fiber hybrid composite material and a preparation method thereof. Background technique [0002] In the past, utility poles and street light poles were mainly made of wood, cement, reinforced concrete or metal steel. With the development of the power industry, road and bridge construction, and municipal construction, the performance requirements for utility poles and light poles are getting higher and higher. From the initial wooden poles to the current cement, reinforced concrete or metal steel poles, the strength of materials, wires The rods are getting bigger and bigger. Although wooden poles are light in weight and easy to move and install, they are no longer used in new lines due to their low strength, resistance to environmental corrosion, and shortage of resources; metal, cement and reinforced concrete poles are rich in raw materials, simple in manufacturing process, and chea...
