Abstract
Abstract A method of casting a fiber-reinforced caliper wherein inorganic fiber is wound up in a direction parallel to the axis of cylinder around a core conforming approximately to the inside shape of the bridge portion of a caliper, the wound-up fiber is cut off in the shape of the bridge, and matrix metal is cast onto the cut-off molding of fiber under high pressure to form the shape of caliper, or the whole shape of caliper is formed by a casting method after the bridge portion is formed by casting under high pressure.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
77 words
A method for casting a fiber-reinforced caliper comprising: (a) winding inorganic fibers around a core in a direction parallel to the cylindrical axis of said core which conforms approximately to the inside shape of the bridge portion of a caliper, (b) cutting off the fibers so wound up into the approximate shape of the bridge, and (c) casting under high pressure matrix metal onto the so cut-off fibers to form it into the shape of a caliper.
Claim 2
Independent Claim
