製造方法に関する。Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention provides fiber differentiated light metals (hereinafter referred to as FR) embedded in light metals such as aluminum and magnesium or their light metal alloys.
This invention relates to a method for producing an alumina-silica fiber molded body used as a reinforcing body for the invention (referred to as M).

ている。In the case of reinforcement for FR:A using short ceramic fibers, are amorphous alumina-silica fibers, crystalline alumina fibers, and crystalline alumina-silica fibers? It is dispersed in water with an inorganic binder such as colloidal alumina or colloidal silica and an organic binder that maintains dry strength, and then suction molded at about 200c for about 24 hours. The molded product is heated to prevent mullite from forming in the amorphous alumina-silica fibers, that is, the molded product shrinks and its dimensions change. It is obtained by heating at 700 to 800C to stabilize the inorganic binder and removing the mixture. This reinforcing body ζ is set in a mold that is sized to fit exactly 3 pieces, and is cast using high-pressure solidification casting. FRM was obtained by casting the light metal using a multi-metal mold.

造上不安定であるため、鋳造時に軽金属溶湯と反応し、
反応物な繊維表面に生成して劣化し、ＦＲＭの耐摩耗性
を除いては金属の補強効果はあまり大きくない。Reinforcement bodies using amorphous alumina-silica fibers are unstable due to their compositional structure, so they react with molten light metal during casting.
Metal is generated on the surface of reactant fibers and deteriorates, and the reinforcing effect of metal is not very large except for the wear resistance of FRM.
これに対し結晶質アルミナ繊維な使用した補強体は上記
のような問題はないが、繊維そのものが製造方法に由来
して非常に高価であり、また繊維そのものは硬いが脆い
ため、成形体にした場合強度が小さく、鋳造時の高圧に
より座屈、変形、割れ等が生ずることがある。On the other hand, crystalline alumina fiber reinforcements do not have the above problems, but the fibers themselves are very expensive due to the manufacturing method, and the fibers themselves are hard but brittle, so it is difficult to make them into molded products. In this case, the strength is low, and buckling, deformation, cracking, etc. may occur due to the high pressure during casting.

部分結晶化アルミナシリカ繊維を用いて上記と同様にし
て補強体を作ることが行なわれている。In order to deal with this problem, amorphous alumina-silica fibers are heat-treated at 900C or higher to crystallize part of the amorphous alumina-silica into mullite (3AlO/2SiO), and this partially crystallized alumina-silica fiber is used to The reinforcing body is made in the same manner as above.

反応してＦＲＭの機械的強度を低下せしめる。This reinforcing material has greater strength than those using crystalline alumina fibers and does not buckle or deform within the mold due to high pressure during casting, and FRM using this material has excellent wear resistance and mechanical properties. A product almost comparable to that using crystalline alumina fibers as reinforcement can be obtained. The fibers of this reinforcing body hardly react with the light metal molten metal, but the highly reactive colloidal alumina and floidal silicate used as an inorganic binder react with the high temperature light metal molten metal, causing the FRM machine. reduce the strength of the target.

It is an object of the present invention to provide a method of manufacturing a reinforcing body for FRM that can be provided at low cost.

The method includes a step of heat-treating as described above, and a step of processing the molded body that has undergone the step.

きる。If the fibers are treated with mullite before molding, the fibers will become entangled and harden at that point, so when dispersing them in water, unless they are broken short, they will not be evenly dispersed and will form lumps. However, when amorphous fibers are dispersed in water, there is no need to forcefully break them to ensure even dispersion, so there is less chance of them breaking and becoming short, and as a result, the fibers are in a good state of entanglement. A molded body is obtained. This is the same as the reinforcement body using amorphous alumina-silica fibers, but since it is made into a molded body and then heat-treated at a high temperature to partially crystallize mullite, the fiber molded body will shrink at this heat treatment temperature. The inorganic binder is more stable than before, and the fibers are bonded more firmly. Through such molding and heat treatment, the material is made into mullite and its strength is improved, which is then machined to the required dimensional accuracy, and then provided as is as a reinforcing molded product, which improves processing accuracy. Improved performance and easier handling. The strength of the FRM can be improved by using a strong reinforcing body in which the fibers are firmly bonded.

At 1400 C for 0.5 to 5 hours, the lower the alumina content, the lower the temperature and the shorter time required, and the more alumina-containing openings, the longer the high temperature and longer time. In the case of the same alumina content, in order to obtain the same mullite conversion rate, heat treatment at a low temperature can be done for a long time, and at a high temperature, a short time is enough. Amorphous alumina-silica fibers consisting of 5% to 9% of other pure substances and 10% by weight of an organic binder are added to the fibers, and floidal silica (solid content 40% by weight) is added to the solids.
