摘要： A sizing composition that permits in-line chopping and drying of reinforcement fibers for reinforcing thermoset resins is provided. The size composition includes at least one coupling agent and one or more blocked polyurethane film forming agents. The blocking agent preferably de-blocks at a temperature that permits simultaneous or nearly simultaneous de-blocking and curing of the polyurethane film former. The sized fiber strands may be chopped to form chopped strand segments and dried in a fluidized bed oven, such as a Cratec® drying oven, in-line. The chopped fiber strands may then be used in a bulk molding compound and molded into a reinforced composite article. Chopping the glass fibers in-line lowers the manufacturing costs for products produced from the sized fiber bundles. Further, because the reinforcement fibers can be chopped and dried at a much faster rate with the inventive size composition compared to conventional off-line chopping processes, productivity is increased.
摘要翻译：提供了一种允许在线切割和干燥用于增强热固性树脂的增强纤维的施胶组合物。尺寸组合物包括至少一种偶联剂和一种或多种封闭的聚氨酯成膜剂。阻聚剂优选在允许同时或几乎同时脱模和固化聚氨酯成膜剂的温度下去嵌段。大小的纤维束可以被切碎以形成短切的链段，并在流化床烘箱（例如干燥烘箱）中进行在线干燥。然后将切碎的纤维束用于大量模塑料并模制成增强复合制品。搪玻璃纤维降低了从尺寸纤维束生产的产品的制造成本。此外，由于与传统的离线切割方法相比，由于本发明的尺寸组合物可以以更快的速度将增强纤维切碎和干燥，所以生产率提高。
