[0033]Material formula (in parts by mass): 40 parts of vinyl ester resin, 1.6 parts of 50% cyclohexanone peroxide solution, 2.4 parts of 6% cobalt naphthenate, 0.32 parts of fumed silica, 0.12 parts of pigments, basalt 60 parts of fiber plain weave, resin transfer molding equipment and vacuum assisted molding equipment, surface treatment of the mold with release agent, basalt fiber plain weave cloth layer by layer 0 / 90 ° cross layer, encapsulation, inspection and sealing, The raw materials are prepared in a container in advance, the vacuum pump is turned on, the resin port is closed, and the resin is sucked and injected. When the resin gradually flows into the resin collector, when the resin has completely infiltrated the fiber and the system has reached equilibrium, the resin port is closed, and then the vacuum port is closed to maintain the vacuum of the system to solidify. The material gels, after curing to the release strength, demolding, and post-curing at 80°C for 4h. The re...

Abstract

The invention provides a method for making a basalt fiber enhanced composite material and the application of the method on making ship bodies. The formula of the method comprises vinyl ester resin or unsaturated polyester resin, a peroxide initiator and a promoter; the resin is injected and solidified and molded under the condition of vacuum aid resin transfer molding by raw material mixing. The method for making the basalt fiber enhanced composite material is characterized in that the raw material contains 30 to 70 percent mass of the basalt fiber as the enhancing material. The technique is used for making the ship bodies of army auxiliary ship and high speed ships, the ship bodies have outstanding aging resistant property, creep resistant property and anti-explosion impact property in addition to excellent mechanical property, ocean environment resistant property and high temperature resistance property, meanwhile, the method for making the basalt fiber enhanced composite material can lower the building cost of ship bodies and prolong the service life of ships.

Description

Technical field [0001] The invention relates to a method for manufacturing basalt fiber reinforced composite material by vacuum-assisted resin transfer molding, in particular to a method for manufacturing basalt fiber reinforced composite material by vacuum-assisted resin transfer molding. On the application. Background technique [0002] Continuous Basalt Fibre (CBF) is the only glass fiber product that has no environmental pollution so far. It uses a volcanic eruptive rock (including basalt and andesite) formed by the condensation of a volcanic eruption as raw material, and is melted at high temperature. Continuous fiber that is drawn quickly afterwards. It is taken from natural ore without any additives, and the main component is SiO 2 Formed with metal ion compounds. The composite material made of basalt fiber as the reinforcing material has outstanding temperature resistance, high tensile strength, excellent resistance to sea water and chemical media, and certain radar steal...
