Continuous carbon fiber reinforced phosphoric acid-based geopolymer composite material and preparation method thereof
The invention discloses a continuous carbon fiber reinforced phosphoric acid-based geopolymer composite material and a preparation method thereof. The preparation method comprises the following steps: vacuum heat treatment on carbon fibers; activation pretreatment of an aluminum-silicon source: calcining the superfine kaolin powder to prepare metakaolin powder; diluting concentrated phosphoric acid into a phosphoric acid solution; and uniformly mixing the metakaolin powder with a phosphoric acid solution to prepare phosphoric acid-based geopolymer slurry; preparation and pretreatent of a mold; forming of the continuous carbon fiber reinforced phosphoric acid-based geopolymer composite material: uniformly printing the slurry on pretreated carbon fibers in a screen printing manner, and then stacking the carbon fibers on a prefabricated mold layer by layer to form a rough blank; curing, demolding and curing; and silicon resin solution surface treatment. The prepared composite material is composed of a phosphoric acid-based geopolymer and continuous carbon fibers uniformly distributed in the phosphoric acid-based geopolymer. The composite material is excellent in mechanical property and outstanding in high and low temperature resistance, and the preparation method is low in energy consumption and cost and simple in process.
