复合材料飞轮研究进展

摘要

本文对比了复合材料飞轮转子与金属材料飞轮转子的性能，指出复合材料比强度高、密度小等特点使其可以使飞轮具有更高的极限转速和储能能力。同时指出了复合材料各向异性的特点使得其垂直纤维方向强度低，限制了飞轮的最高转速。介绍了目前复合材料飞轮主要采用单层圆环飞轮和多层圆环飞轮2种结构形式。同时指出采用柔性树脂基体，改善树脂和纤维的界面粘结状态和增强树脂本身的强度也是提高复合材料径向强度的有效途径。%This paper compares the performance of the composite flywheel rotor and the metal flywheel rotor ,The fly-wheel can have higher limit speed and more energy storage capacity for the high strength and low density of composite mate -rials.The anisotropy of the composite material limits the maximum speed of the flywheel .Two kinds of structure of composite flywheel are introduced .The single-ring flywheel and the multi-ring flywheel .Using the flexible resin matrix ,enhancing the interface performance of resin and fiber ,reinforcing the strength of resin concrete can improve the strength of composite ma-terials.
