Problems solved by technology

[0003] With the continuous development of shipbuilding and other industrial technologies, the domestic demand for corrosion-resistant materials has been expanding in recent years. Traditional GFRP ship material reinforcement substrates are mainly non-alkali fibers. The main problems of ordinary non-alkali glass fiber reinforced composite materials are as follows , which limits the application of GFRP in the field of ships, especially large ships
1) Ordinary alkali-free fiber-reinforced GFRP materials have low elastic modulus, lower shear modulus, and low interlaminar shear strength, which limit their application in large ships; 2) Compared with traditional steel materials, alkali-free GFRP is resistant to Corrosion performance and anti-fouling performance have been improved, but China's sea area is vast, and the marine environment is quite different from the north to the south. Ordinary alkali-free fiber GFRP has poor long-term temperature resistance and corrosion resistance, and there is aging phenomenon; 3) Ordinary alkali-free GFRP materials have room temperature creep. The deformation phenomenon has a great influence on the hull material after molding

The invention discloses a corrosion-resistant high-strength high-modulus fiber and a fabric prepared therefrom. The corrosion-resistant high-strength high-modulus fiber is composed of the following components: SiO2: 55-65%, Al2O3: 12-18%, MgO: 8 ~14%, CaO: 5~13%, Li2O: 0.2~1%, TiO2: 1~2%, and the balance is impurities, and the stated percentages are mass percentages. The fabric obtained in the present invention has high strength, high elastic modulus, high shear modulus, long-term temperature resistance, good corrosion resistance, and is not easy to age, and there is no room temperature creep phenomenon in composite material products; high-strength and high-modulus compound sizing agent for wire drawing Directly coated with raw silk, after making high-strength and high-modulus fabric, it can be directly compounded with resin, and the fabric does not need to be post-treated; the structure of the glass fiber fabric of the present invention is preferably twill or satin, suitable for various post-processing such as hand lay-up or vacuum-assisted molding. processing technology.

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...
