摘要： Uncured elastomeric sheet material (42) is built up on the outer surface of a production article (36) constructed from composite materials. A vacuum bag system (20, 24, 26, 30, 32) is used for holding the uncured elastomer member (60) against the composite article (36) while the elastomer member (60) is being cured under heat and pressure. Such curing causes the elastomer member (60) to shrink. The elastomer member (60) is then resized by cutting it into sections (66). The sections (66) are placed back on the composite article (36) and each is positioned on such article (36) at a location best conforming to it in shape. This leaves gaps (68) between the sections (66). Additional uncured elastomer (70) is applied to fill the gaps (68) and bridge across the gaps (68), to in that manner splice the sections (66) together. A vacuum bag (20, 24, 26, 30, 32) is again applied and the bag assembly (20, 24, 26, 30, 32 ) is again cured under heat and pressure, to cure the additional elastomer material (70). The elastomer member (60") formed in this manner substantially conforms in size and shape to the production composite article (36) and can be used as a pressure pad in the manufacture of additional articles (36) of the composite material.

摘要翻译： 未固化的弹性体片材（42）被构建在由复合材料构成的生产制品（36）的外表面上。 当弹性体构件（60）在热和压力下固化时，真空袋系统（20,24,26,30,32）用于将未固化的弹性体构件（60）保持在复合制品（36）上。 这种固化使得弹性体构件（60）收缩。 然后通过将弹性体构件（60）切割成部分（66）来调整弹性体构件（60）。 将部分（66）放置在复合制品（36）上，并且每个部分（66）被放置在最适合其形状的位置处的这种制品（36）上。 这留下了部分（66）之间的间隙（68）。 施加另外的未固化弹性体（70）以填充间隙（68）并穿过间隙（68），以这种方式将部分（66）拼接在一起。 再次施加真空袋（20,24,26,30,32），并且袋组件（20,24,26,30,32）在热和压力下再次固化，以固化附加的弹性体材料（70）。 以这种方式形成的弹性体构件（60“）基本上符合生产复合制品（36）的尺寸和形状，并且可以用作制造复合材料的附加制品（36）的压力垫。
