<p>PROBLEM TO BE SOLVED: To provide a fiber reinforced hydraulic composition excellent in heat resistance and machinability, having a sufficiently high strength and impact resistance, thereby enabling application to machine parts, and also provide a fiber reinforced hydraulic formed body obtained by using the composition. SOLUTION: This fiber reinforced hydraulic composition includes a powder mixture comprising 20-90 wt.% of a hydraulic powder and 10-80 wt.% of a non-hydraulic one, a machinability improver in an amount of 2-18 wt.% based on 100 wt.% of the powder mixture and 1-5 wt.% of two or more reinforcing fibers, the elasticity coefficients of which are different from each other, concretely comprising the fiber having a higher elasticity than the hydraulic formed body excluding the fiber and the fiber having the elasticity lower than that thereof.</p> |
