を有していた。As one method of weight reduction, it has been noted that carbon fibers having high specific strength and specific elastic modulus are compounded. For example, Japanese Patent Application Laid-Open No. 63-55146 proposes a fiber-reinforced inorganic material in which an inorganic material such as cement and a woven structure of reinforcing fibers such as carbon fibers are combined.
In this proposal, the size of the woven tissue is 5 to 150 mm.
The inorganic material penetrates into the openings of the woven tissue, and the woven tissue is completely covered with the inorganic material. Therefore, when a tensile stress is applied to the surface layer having no reinforcing fiber, cracks are easily formed, and the growth of the cracks causes a problem that strength and toughness are reduced.

However, in the case of a hydraulic inorganic material having a high water content and a high water absorption, the adhesive strength is reduced due to penetration of moisture. Therefore, a high reinforcing effect has not been obtained.
