Chopped carbon fiber reinforced phosphoric acid-based geopolymer composite material and preparation method thereof
The invention discloses a chopped carbon fiber reinforced phosphoric acid-based geopolymer composite material and a preparation method thereof. The preparation method comprises the steps: preparing a SiO2-Al2O3 sol precursor, preparing the precursor into gel, drying, and calcining the dried gel to prepare SiO2-Al2O3 active powder; mixing the pretreated chopped carbon fibers and the SiO2-Al2O3 active powder, carrying out ball milling and then drying, and thus preparing SiO2-Al2O3 composite powder containing the chopped carbon fibers; adding the SiO2-Al2O3 composite powder containing the chopped carbon fibers into a phosphoric acid solution, and uniformly mixing; carrying out injection molding and curing; demolding and curing; and carrying out surface treatment with a silicon resin solution. The prepared composite material is composed of a phosphoric acid-based geopolymer and the chopped carbon fibers dispersed in the phosphoric acid-based geopolymer. The composite material has the advantages of ultrahigh ductility, low water absorption rate, high temperature resistance, low cost and the like, and the preparation method is simple to operate and low in cost.
