Abstract

The invention discloses a preparation device and a preparation method of a glass fiber composite material for liquid hydrogen storage. The preparation method is characterized by comprising the following steps: step 3, founding: placing the glass fiber composite material in founding equipment for glass founding, conducting melting while stirring in a temperature range of 1510-1550 DEG C, and carrying out founding for 24 hours to obtain clarified and homogenized glass liquid; step 4, cooling: placing molten glass flow on a heat-resistant steel plate, and carrying out cooling so as to obtain a glass block; and step 5, fiber drawing: placing a certain mass of glass in a single-hole drawing crucible, adjusting the temperature and liquid level height of molten glass and the rotating speed of a drawing machine, and preparing required glass fibers. The invention relates to the technical field of glass fibers. According to the invention, a main component content is changed, so a glass fiber network structure is compact, and thus, tensile strength is increased compared with the tensile strength of an existing high-strength glass fiber product; and the tensile strength of an epoxy resin system composite material reinforced by using the fibers is improved, and the temperature resistance, the acid resistance and other properties of the epoxy resin system composite material are substantially improved.

Description

technical field [0001] The invention relates to the technical field of glass fibers, in particular to a preparation device and a preparation method of a glass fiber composite material for liquid hydrogen storage. Background technique [0002] Glass fiber is an inorganic fiber material. It can be used to strengthen resin to make composite materials with excellent performance. There are many kinds of glass fibers. The advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, low thermal conductivity and sound absorption. It has been widely used in aerospace, military chemical and other fields in recent years, but its shortcomings are brittleness, poor wear resistance, and poor polymerization performance. These shortcomings restrict its application in many fields. If you want to increase its range of use, it needs to be compounded and modified. [0003] In the preparation process of the existing glass fiber composite materials...
