    • Fiber-reinforced structures comprising a thermoplastic polymer (53) and containing between 30 % and 60 % by weight of reinforcing filaments arrayed randomly or aligned within the structure have been produced in a continuous process and have high cantilever, tensile and flexural strength, high stiffness, low creep and low relative cost. The high strength and stiffness result from compatibilizing of natural fibers (51) and the thermoplastic matrix (53) by wetting or coating of fibers (51) between 1 mm and 20 cm in length with maleated polypropylene coupling agents (55) and, optionally, with a small volume of phenolic or epoxy resins. The mixed material is further processed by molding (65) under conditions in which material temperatures are maintained below 230 DEG C and pressure is held below 28,000 psi.
    • 包含热塑性聚合物(53)并含有30%至60%(重量)在结构内随机或排列的增强细丝的纤维增强结构已经以连续的方法生产,具有高悬臂,拉伸和弯曲强度,高刚度 低蠕变,相对成本低。 通过用马来酸化的聚丙烯偶联剂(55)将长度在1毫米和20厘米之间的纤维(51)进行润湿或涂覆,天然纤维(51)和热塑性基质(53)的相容性得到高强度和刚度, 与少量酚醛或环氧树脂。 在材料温度保持在230℃以下且压力保持在28,000psi以下的条件下,通过模制(65)进一步处理混合材料。
