The Cf-SiCf-(Al2O3p)/KGP composites were successfully prepared by the method that mixing a kind of hybrid fiber preform pre-developed and geopolymer resin. The synergistic effects of the hybrid fibers and Al2O3 particles on the composites were investigated. Results show that all the composites showed typical amorphous structure. Mechanical properties of the Cf-SiCf-(Al2O3p)/KGP composites were improved remarkably due to the addition of the hybrid fibers and Al2O3 particles. The flexural strength and Young’s modulus of the Cf-SiCf-(Al2O3p)/KGP composites with 1 mm length SiCf were reached 62.4±2.1 MPa and 24.1±1.6 GPa, respectively. The Cf-SiCf-(Al2O3p)/KGP composites showed non-catastrophic behavior rather than the catastrophic failure.
