Continuous-fiber reinforced plastics are superior mechanically to short-fiber reinforced plastics. However, components fabricated from continuously reinforced plastics are labor-intensive, time consuming and expensive. In phase I and in response to industrial demand, an innovative system to mold quality, discontinuous long- fiber, reinforced plastic products to net dimension was developed. Results of the American Society of Testing Materials test specimens molded from either virgin or virgin/recycled materials and scanning electron microscope and ashing data, substantiate the advantageous mechanical/physical performance of such composite components. The mechanical advantages were achieved without sacrificing the design and processing flexibilities or economical advantages of using short-fiber composites. The use of recycled feed-stock also has favorable environmental implications. In phase II the pioneer equipment will be developed into a prototype system for its commercialization and that of its products. The use of other virgin and recycled feed-stock materials will be evaluated and process optimization for molding various materials into industrial products will be conducted.

连续纤维增强塑料具有上级机械性能 短纤维增强塑料。 然而，制造的组件 从连续增强塑料是劳动密集型，时间 消耗和昂贵。 在第一阶段， 需求，创新系统，以模具质量，不连续长， 纤维增强塑料制品的净尺寸开发。 美国材料试验协会测试样本的结果 由原始或原始/回收材料成型，并扫描 电子显微镜和灰化数据，证实了有利的 这些复合材料部件的机械/物理性能。 的 在不牺牲设计的情况下， 和加工灵活性或使用的经济优势 短纤维复合材料 使用回收的原料也具有 有利的环境影响。 在第二阶段，先锋设备将发展成为一个 原型系统的商业化和其 产品. 使用其他原始和回收的原料 材料将被评估和工艺优化成型 将各种材料转化为工业产品。
