The invention relates to a composite material mold and a manufacturing method thereof. The method comprises the following steps: (i) paving a fiber surface felt on a female mold; (ii) paving a fiber woven fabric layer on the fiber surface felt; (iii) paving a sewed and woven fabric layer on the fiber woven fabric layer so as to obtain a paved prefabricated body; (iv) introducing pouring resin intothe paved prefabricated body through a vacuum pouring manner, and carrying out curing, post-treatment and de-molding to obtain the composite material mold. The invention further provides the composite material mold prepared by the method. The method provided by the invention has the advantages of low cost, small processing difficulty, short production period and the like; the prepared composite material mold has the advantages of good temperature resistance, high mold precision, light weight and the like; the problems of surface cracks, deformation and the like of a traditional composite material mold are overcome; the composite material mold has a great potential market in the fields of manufacturing aircrafts, vehicles and the like.
