    • A method provides for full or partial infusion of resin into three-dimensional, woven textile preforms (23). Resin film (41, 45) is placed at selected locations adjacent the preform, and the resin film may be separated from other areas of the preform using separator sheets (43) or other materials. The preform is heated and may be vacuum-bagged to apply pressure, or may be rolled or fed through a die. The heat and pressure cause the resin to infuse into the selected areas of the preform adjacent the resin films. The amount of resin in the partial infusion is the same as is necessary to fully infuse the preform, but the resin remains localized in the selected areas until heated again at cure to cause the resin to flow throughout the preform. The method may also be used to fully infuse the preform with resin by providing sufficient temperature and time at that temperature during the initial infusion.
    • 一种方法提供将树脂全部或部分输注到三维编织织物预制件(23)中。 将树脂膜(41,45)放置在与预成型件相邻的选定位置处,并且可以使用隔板(43)或其它材料将树脂膜与预成型件的其它区域分离。 将预成型件加热并且可以被真空包装以施加压力,或者可以卷起或通过模具进料。 热和压力导致树脂注入到与树脂膜相邻的预成型件的选定区域中。 部分输注中的树脂量与完全注入预成型件所需的量相同,但是树脂保持定位在所选择的区域中,直到在固化时再次加热以使树脂流过整个预制件。 该方法还可用于在初始输注期间通过在该温度下提供足够的温度和时间来充分地注入树脂。
