摘要： Apparatus and a method of preparing fiber preforms disperses fibers and binder on a forming support surface such that the materials are conditioned and then applied to the surface where the composite material solidifies. Reinforcing material, such as fiber, is mixed with binder, such as thermoplastic or thermoset materials, so that the materials adhere. Then, the adhesive mixture is dispersed in a controlled pre-determined weight ratio on the support surface where the mixture sticks to the support surface, cools and solidifies. The deposited mixture can be an open mat having interstices between fibers. The deposited mixture can also be shaped further into a final desired shape before complete solidification. This method eliminates the need for solvents and their associated problems. The process does not require a vacuum or plenum system to hold the reinforcing material in place. The preform can be made in any shape, including sections or asymmetric configurations and remain in mold while being processed to a composite molded article.
摘要翻译：设备和制备纤维预制件的方法将纤维和粘合剂分散在成形支撑表面上，使得材料被调节，然后施加到复合材料固化的表面上。诸如纤维的增强材料与粘合剂如热塑性或热固性材料混合，使得材料粘附。然后，粘合剂混合物以受控的预定重量比分散在支撑表面上，其中混合物粘到支撑表面上，冷却并固化。沉积的混合物可以是在纤维之间具有间隙的开放垫。沉积的混合物还可以在完全固化之前进一步成型为最终所需的形状。该方法消除了对溶剂及其相关问题的需要。该过程不需要真空或增压系统来将增强材料保持在适当位置。预成型件可以制成任何形状，包括部分或不对称构型，并保持在模具中同时被加工成复合模制品。

摘要： A method of making a preform in a mold, where the mold is adapted so that the preform remains in-mold during subsequent processing to a composite molded article, is disclosed. The method comprises the steps: (a) providing reinforcing material, (b) providing binder blend material, (c) mixing the reinforcing material and the binder blend material in a venturi so that the binder material adheres to the reinforcing material, (d) applying a stream of the mixture exiting from a constricted opening of the venture through a heating zone to a prepared surface of a mold tool, where the applying is conducted without use of a plenum system, (e) applying a stream or curtain of gaseous cooling media to the material on the prepared surface, and (f) sufficiently solidifying the mixture to form the preform in the mold, where the preform remains in the mold during subsequent processing to a composite article.
