摘要： A process for the production of structural and semi-structural composites formed by compressing planar layers of nonwoven preform materials formed from aqueous blends of reinforcing fibers and thin thermoplastic fluoropolymer flake. The flakes have an irregular periphery with microfibrils extending therefrom, having a Canadian Standard Freeness of from 800 to 883. The planar layers which are unconstrained in the in-plane direction are preconsolidated by heating the layer to above the melting point of the fluoropolymer, the applying pressure normal to the plane of the layer causing the fluoropolymer to flow thus orienting the fibers in the plane of the layer. The composites are useful in applications which require higher strength and/or modulus, and where chemical and/or heat resistance is needed, as in chemical processing.

摘要： A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient preheating of the sheel prior to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, tacking them together at crossover points. The resultant web can then be directly heated very efficiently for molding. This web is highly porous allowing rapid heating at moderate pressure differentials during subsequent preheat steps. The microstructure created when the resin matrix forming fibers are initially melted further enhances heating capability because the structure retains porosity during the subsequent heating step required for molding. Because the resin matrix forming fibers initially were uniformly blended, a highly uniform distribution of polymeric material within the reinforcing fiber matrix yields molded parts with very uniform properties.
摘要翻译：已经开发了制备多孔纤维增强聚合物复合片材的方法，以允许在模制之前更有效地预热剪切，并且包括将增强纤维与树脂基质形成纤维混合以形成网的步骤。然后将该网加热至其中形成树脂基质的纤维熔化并包裹增强纤维的温度，并在交叉点将它们粘合在一起。然后可以非常有效地直接加热所得的纤维网以进行模塑。该网是高度多孔的，允许在随后的预热步骤中以适当的压力差快速加热。当树脂基质形成纤维最初熔化时，产生的微观结构进一步增强了加热能力，因为该结构在随后的成型所需的加热步骤期间保持孔隙率。由于初始形成树脂基质的纤维被均匀地混合，所以在增强纤维基体内聚合物材料的高度均匀分布产生具有非常均匀性质的成型部件。
