【摘要】 本文介绍一种维纶增强酚醛模塑料的研制。研究了它的配方、制备工艺和主要性能。该塑料是一种同类组份复合材料,具有较高的化学均一性和物理均一性。因此它不仅在初始状态具有较高的使用性能,而且在各种外界因素长期作用下,也具有较大的稳定性。此外,其制备工艺简易,价格低廉。并为维纶的应用打开了一个新领域。该材料已在生产中使用。更多还原

【Abstract】 A polyvinyl alcohol (PVA)fiber reinforced phenolic mouldingplastics was developed. The for-mula, process of manufacture andproperties were studied.The com-posite material, whose matrix andreinforcement are composed of thesame kind materials,is of excellentchemical and physical uniformity.The moulding plastics is of highoriginal properties, better enduringproperties and stability under env-ironmental conditions. Its processis eay and simple. and the cost islow. A new region was developedfor using PVA fiber. The mouldingplastics has been used.更多还原
