    Abstract: A short length of a multiwire strand is surrounded with a mold to provide an annular space about said length. Said space is filled with a thermosetting plastic sealant and pressure is applied to force said sealant into and along the interstices of said strand. During said application of pressure, the strand is circumferentially heated at the ends of said mold to provide a radial temperature gradient across said ends. Pressure is applied to said sealant until the ends of the seal are substantially convex.

    Abstract: A method of making metal fiber reinforced plastic composite from a mixture of ferrous fibers and sacrificial metal fibers. The sacrificial metal fibers may be ferrous fibers coated with a sacrificial metal or may be composed throughout of a sacrificial metal such as zinc having a greater electro negativity than iron. The fibers may also comprise ferrous fibers coated with a sacrificial metal mixed with solid sacrificial metal fibers. The ferrous and sacrificial metal fibers are cut into fairly short lengths and are then blended thoroughly together in predetermined ratios with plastic powder in suitable blenders to form a uniform mix having the sacrificial metal fibers thoroughly dispersed throughout the ferrous metal fibers and the plastic. The blend of metal fibers and plastic is then placed in a mold or other plastic forming apparatus and molded into a desired shape. The final molded plastic composite is corrosion resistant on cut surfaces due to the presence of the sacrificial metal fibers within a distance of the ferrous fibers effective to form galvanic corrosion couples between the ferrous and sacrificial metal fibers.

    Abstract translation: 从铁质纤维和牺牲金属纤维的混合物制备金属纤维增强塑料复合材料的方法。 牺牲金属纤维可以是涂覆有牺牲金属的铁纤维，或者可以由诸如锌的牺牲金属整体组成，其具有比铁更大的电负性。 纤维还可以包含涂覆有与固体牺牲金属纤维混合的牺牲金属的铁质纤维。 将铁和牺牲金属纤维切割成相当短的长度，然后以合适的搅拌机中的塑料粉末以预定比例充分混合，以形成均匀的混合物，其牺牲金属纤维完全分散在整个含铁金属纤维和塑料中。 然后将金属纤维和塑料的混合物放置在模具或其它塑料成型设备中并模制成所需的形状。 最终的模制塑料复合材料在切割表面上是耐腐蚀的，因为在有色金属纤维的距离内的牺牲金属纤维的存在有效地在亚铁和牺牲金属纤维之间形成电偶腐蚀。
