Embodiment Construction

[0067] The technical solution of the present invention is specifically described below through examples, and the content of the present invention is not subject to any restriction by the following examples. Wherein the total content of the components in the examples is slightly less than 100%, it can be understood that the residual amount is a small amount of impurities or a small amount of components that cannot be analyzed.

[0068] The specific process of the embodiment of the present invention is as follows: each component can be obtained from appropriate raw materials, the various raw materials are mixed in proportion, so that each component reaches the final expected weight percentage, the mixed batch is melted and clarified, Then the molten glass is pulled out through the nozzle on the bushing to form glass fibers, which are drawn and wound to the rotating head of the wire drawing machine to form raw silk cakes or yarn clusters. These glass fibers can be further processe...

Abstract

The invention discloses a glass fiber capable of being used as an advanced reinforced substrate of a composite material, comprising the following components in percentage by weight: 57 to 65 percent of SiO2, 14 to 20 percent of Al2O3, 8 to 13 percent of CaO, 7 to 12 percent of MgO, less than 23 percent of CaO and MgO, 0.05 to 2 percent of Na2O and K2O, and 0.05 to 1 percent of Fe2O3. While the mold temperature, the liquidus temperature and the refining temperature of the glass fiber are maintained to be relatively low, through optimization and combination of the components, the mechanical performance of the glass fiber is greatly improved compared with conventional E glass fiber, and the increase range of monofilament strength can be increased up to 26 percent, and the total cost of the glass fiber is possibly close to or lower than the cost of the conventional E glass fiber, thus being easy for implementing large-scale industrial production.

Description

(1) Technical field [0001] The invention relates to a glass fiber, in particular to a high-performance glass fiber that can be used as a reinforced base material for advanced composite materials. (2) Background technology [0002] Glass fiber belongs to inorganic fiber material, and it can be used to reinforce resin to make composite material with excellent performance. High-performance glass fiber, as the reinforcing substrate of advanced composite materials, was originally mainly used in the fields of national defense and military industries such as aviation, aerospace, and weapons. With the advancement of science and technology and economic development, high-performance glass fiber has been widely used in civil and industrial fields such as motors, wind blades, pressure vessels, offshore oil pipelines, sports equipment, and automobiles. [0003] Since Owens-Corning of the United States developed S glass fiber, various countries have competed to develop and produce high-p...
