1. A method for preparing an aluminum borate whisker reinforced and toughened non-metallic matrix composite, which includes a non-metallic material reinforced and toughened with aluminum borate whiskers, the method comprising:
a) mixing the aluminum borate whiskers and the non-metallic material by ball milling to form a mixture, wherein in the step a), the aluminum borate whiskers and the non-metallic inorganic material are placed into a ball mill pot and ball milled by zirconia balls; and
b) sintering the mixture by a vacuum hot press method when the non-metallic material is a non-metallic inorganic material, wherein during the sintering at step b), the aluminum borate whiskers are reduced by solid carbon and partially gasified carbon from separator carbon paper, graphite mold, graphite heater, and/or carbon felt,
wherein the sintering is conducted at a temperature of 1480° C. to 1500° C.; and
the aluminum borate whiskers account for 10 to 20% by volume of the aluminum borate whisker reinforced and toughened non-metallic matrix composite.
