Abstract

The invention discloses a corrosion-resistant high-strength high-modulus fiber and a fabric prepared from the fiber. The corrosion-resistant high-strength high-modulus fiber consists of the following components in percentage by mass: 55%-65% of SiO2, 12%-18% of Al2O3, 8%-14% of MgO, 5%-13% of CaO, 0.2%-1% of Li2O, 1%-2% of TiO2 and the balance of impurities. The fabric obtained by the fiber disclosed by the invention has high strength, high elastic modulus, high shear modulus, long-term temperature resistance and corrosion resistance, and difficulty in ageing. Moreover, the composite material product does not have a room temperature creep phenomenon. A high-strength high-modulus compound impregnating compound for wiredrawing is directly coated on yarns to prepare a high-strength high-modulus fabric which can be directly compounded with resin, and does not need after-treatment. The organization structure of the glass fiber fabric is preferably twill weave or satin weave, and is suitable for various post-processing processes such as manual pasting or vacuum auxiliary forming.

Description

technical field

[0001] The invention relates to a corrosion-resistant high-strength high-modulus fiber and a fabric prepared therefrom, belonging to the field of high-performance glass fiber products. Background technique

[0002] In 1958, China's first polyester GFRP (fiberglass reinforced plastic composite) working boat was successfully developed in Shanghai. In the following year, Beijing successfully manufactured the first epoxy GFRP motorboat in China, which opened the prelude to GFRP shipbuilding in southern and northern China. . After more than 50 years of development, hundreds of GFRP shipyards have been formed in China, and the annual production capacity of GFRP boats has reached 7,000 to 8,000. It has been included in the national key scientific and technological research plan, which has strongly promoted the application of GFRP in the field of ships.

[0003] With the continuous development of shipbuilding and other industrial technologies, the domestic demand f...
