Preparation of Carbon Fiber Reinforced Geopolymer Composites

Abstract:

The carbon fiber reinforced geopolymer composites were synthesized with metakaolin, water glass and short carbon fibers. The surface treatment short carbon fibers are homogeneously distributed in the geopolymer matrix. The composites exhibit excellent mechanical properties and electrical conductivity. The flexural strength of the Cf /geopolymer composites reached 27 MPa with carbon fiber content of 2.78 %, and its electrical conductivity are increased from 10^-5 to 10^-1 S.m^-1. However, when the carbon fiber content exceeded 4.15 %, the conductivity of the composites kept a constant.
