杜邦公司发展的“FP/铝”纤维是由多晶氧化铝纤维组成的复合材料。该纤维以不同的密度和不同的排列方向来提高其强度.由于这种材料具有高的热稳定性,很适宜于作为以金属为基体的强化复合材料,用类似失蜡浇铸的方法,使纤维混凝于金属中。这种金属可以是铝、镁、铅、锌和铜。“FP/铝”纤维零件可在陶瓷或不锈钢铸模中将溶化的金属用真空渗入法铸成。这种定向纤维约占总体积的50～55%。“FP/铝”纤维的典型性能如下:
DuPont’s “FP / Aluminum” fiber is a composite of polycrystalline alumina fibers. The fibers increase their strength in different densities and in different orientations Because of their high thermal stability, this material is well suited as a metal matrix-based reinforcing composite in a process similar to lost wax casting, with fibers Coagulation in the metal. This metal can be aluminum, magnesium, lead, zinc and copper. The “FP / Aluminum” fiber parts can be melted metal in a ceramic or stainless steel mold by vacuum infiltration casting. This oriented fiber accounts for about 50-55% of the total volume. The typical properties of “FP / Aluminum” fibers are as follows:
