    • A method for making a composite rivet (30) and upsetting the composite rivet after the riva has been inserted through (e.g., composite) structural members (34, 36) to be held together. The rivet (30) includes a core (1) having continuous and unidirectionally extending fibers (3) that, are reinforced by a thermoplastic resin. The core is surrounded by a braided jacket (5) having fibers (7) arranged in a criss-cross weave. A forming die guide (50) having a containment opening (58) extending therethrough is positioned so that the upstanding end (38) of the composite rivet (30) is received within the containment opening (58). A heated forming die (40) having a forming cavity (44) is moved into the containment opening (58) of the forming die guide (50) so as to lie in axial alignment with the upstanding end of the rivet (30). A ram (52) force the heated forming die (40) through the containment opening (58) so that the upstanding end (38) of the rivet is softened and upset within the forming cavity (44). The ability of the upstanding end (38) of the rivet (30) to spread out under the heat and pressure generated by the heated forming die (40) is limited by the containment opening (58) of the forming die guide (50).
    • 一种用于制造复合铆钉(30)的方法,并且在已经插入铆钉(例如,复合)结构构件(34,36)之后将复合铆钉镦锻以保持在一起。 铆钉(30)包括具有由热塑性树脂增强的连续和单向延伸的纤维(3)的芯(1)。 芯部由编织夹套(5)包围,该护套(5)具有布置成十字交织的纤维(7)。 具有延伸穿过其中的容纳开口(58)的成型模具引导件(50)被定位成使得复合铆钉(30)的直立端(38)被容纳在容纳开口(58)内。 具有成形腔(44)的加热成形模具(40)被移动到成形模具引导件(50)的容纳开口(58)中,以与铆钉(30)的直立端轴向对准。 冲头(52)迫使加热的成形模具(40)通过容纳开口(58),使得铆钉的直立端(38)在成形腔(44)内软化和镦锻。 铆钉(30)的直立端(38)在加热成形模(40)产生的热和压力下展开的能力受成形模导向件(50)的容纳开口(58)的限制。
