    • A method for consolidating a preform (40) made of composite material. The preform and a compliant metal alloy sheet (44) are placed between less compliant matched confronting forming/molding surfaces (18,20) with the preform being sandwiched between the metal alloy sheet and a matched confronting surface. The matched confronting surfaces and compliant metal alloy sheet are heated until the preform reaches at least its consolidation temperature. During heating, force is applied so that the matched confronting surfaces exert sufficient compressive force on the preform and metal alloy sheet to cause the composite material to consolidate at the consolidation temperature. The metal alloy sheet has a tensile yield point in a range of 0.17-2 Mpa (25-300 psi) at the consolidation temperature at a strain rate of about 1 % to 10% strain per minute.
    • 一种用于固结由复合材料制成的预成型件(40)的方法。 将预成型件和顺从金属合金板(44)放置在不太顺从的相对成型/成型表面(18,20)之间,预成型件夹在金属合金板和匹配的相对表面之间。 将匹配的相对表面和柔顺金属合金板加热直到预制件至少达到其固结温度。 在加热过程中,施加力,使得匹配的面对表面在预成型件和金属合金板上施加足够的压缩力,以使复合材料在固结温度下固结。 金属合金板在固化温度下的拉伸屈服点为0.17-2Mpa(25-300psi),应变速率为约1%至10%应变/分钟。
