本発明は短繊維プリフォーム体に心金を用いて成形時の
プリフォーム体の強度を向上せしめた繊維強化ディスク
ブレーキキャリパに関するものでおる。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fiber-reinforced disc brake caliper in which a mandrel is used in a short fiber preform to improve the strength of the preform during molding.

たりする不具合の生ずることを認めた。Therefore, the present inventor investigated a method of preforming metal or ceramic short fibers into a felt shape and casting this preform body in a light alloy to make a caliper. When the preform is composited with a light alloy, it has been found that using only short fibers causes problems such as deformation and cracking of the preform.

金と副え木が一体のものであってもよい。(Means for Solving the Problems) The gist of the present invention is to form a preform by wrapping part or all of the mandrel with a fel (~-shaped molded product) of metal short fibers and/or ceramic short fibers. This fiber-reinforced disc brake caliper is characterized by being made by casting this preform body with metal, and this core metal has 01
It is also possible to use soegi in combination; in that case, the core metal and splint may be integrated.

。(Operation and Effects of the Invention) The purpose of the preform body used in the present invention is to improve the rigidity and strength of the caliper, and according to the present invention, the strength of the preform body is increased by the mandrel. Further improvement in the resulting caliper strength is expected.

一層効果的である。As described above, according to the present invention, the short fibers are formed into a felt shape and preformed using a core metal in the center, and this preform body is placed in a mold to cast a light alloy or the like. At the same time, the preform body is cast, casting,
In addition to having a remarkable effect on improving the strength of the preform by preventing it from deforming or cracking during casting, it is also extremely effective in positioning the preform within the caliper (locating it at the center of the caliper). The use of splints is even more effective.
