金属基复合材料(简称 mmc)的加工成本往往高于聚合物基复合材料所需的

The processing cost of metal matrix composites (mmc for short) is often higher than the high processing temperatures required for polymer matrix composites. The manufacture of metal matrix composites usually requires the use of an intermediate, called a preform, whose shape is sheet, linear, cylindrical or near-net shape. The size and shape of the preform are the same as the composite product to be manufactured. The preforms contain reinforcing materials, usually bonded together by a binder of polymer (such as acrylic acid, styrene), ceramic (such as silica, aluminum metaphosphate) or the base metal itself. For example, continuous fibers are wound around the drum and combined with resin, and then the wound fiber tube is cut from the drum and stretched into a sheet. In the subsequent composite manufacturing process, the organic binder evaporated. For example, short fibers are combined with a ceramic or polymer binder and a liquid carrier to form a slurry, which is then filtered or wet pressed under pressure to form a wet "cake", which is then dried to form a preform. When using the base metal as a binder, the continuous fiber bundle is immersed in the base metal melt for penetration, thereby forming a wire preform; alternately, the fibers placed on the base metal foil are covered with sprayed base metal and fixed in place Position to form a sprayed preform.

The processing cost of metal-based composites (mmc) is often higher than the high processing temperatures required for polymer-based composites. The manufacture of metal-based composites usually requires the use of an intermediate, called a prefab, in a flaky, linear, cylindrical, or near-clean shape. The size and shape of the prefabricated parts are the same as the composites to be manufactured. Prefabricated blanks contain reinforced materials, usually bonded together by polymers (e.g. acrylic, styrene), ceramics (e.g. silica, aluminum phosphate) or the adhesive of the substrate metal itself. For example, continuous fibers are wrapped around the drum and combined with the resin, then the entangled fiber cartridge is cut off from the drum and stretched into thin sheets. The organic adhesive evaporated during the subsequent composite manufacturing process. For example, short fibers combine with ceramic or polymer adhesives and liquid carriers to form slurry, then filter or wet pressure under pressure to form a wet "cake" and then dry to form a prefab. When the base metal is used as a binder, the continuous fiber bundle is immersed in the substrate metal melt for infiltration, thus forming a wire prefab; Alternately, the fibers placed on the base foil are covered with spray-based base metal and fixed in place to form a spray precast.

The processing cost of MMC is often higher than the high processing temperature required by polymer matrix composites. The manufacture of metal matrix composites usually requires the use of an intermediate, called a preform, whose shape is sheet, linear, cylindrical or near net shape. The size and shape of the prefabricated parts are the same as the composite products to be manufactured. Preforms contain reinforcing materials, usually bonded together by polymers (such as acrylic acid, styrene), ceramics (such as silicon dioxide, aluminum metaphosphate), or adhesives of the base metal itself. For example, a continuous fiber is wound around the drum and combined with resin, and then the wound fiber drum is cut from the drum and stretched into a sheet. In the subsequent composite manufacturing process, the organic binder evaporated. For example, short fibers are combined with ceramic or polymer adhesives and liquid carriers to form a slurry, which is then filtered or wet pressed under pressure to form a wet "cake" and then dried to form a preform. When the base metal is used as the binder, the continuous fiber bundle is immersed in the base metal melt for infiltration, so as to form the wire preform; alternatively, the fiber placed on the base metal foil is covered with the spraying base metal and fixed in a proper position, so as to form the spraying preform.
