摘要: 采用张力缠绕工艺制作的复合材料护套是预防高速永磁电机转子永磁体在离心力载荷下破坏的有效途径。本文针对复合材料缠绕结构缠绕张力对其材料强度影响的多因素竞争关系,设计并开展了不同张力缠绕复合材料NOL(Naval Obdnance Laboratory)环强度实验、缠绕结构固化残余应力实验,获得了缠绕张力对复合材料的材料强度、缠绕结构残余应力的影响规律,分别采用混合率和代表体元方法建立了缠绕张力影响及纤维体分比变化规律的纤维缠绕材料拉伸强度理论估测方法,阐释了缠绕张力导致复合材料强度影响机理,为缠绕复合材料结构选择合适的缠绕张力范围提供了参考。

Abstract: The composite sleeve made by tension winding is an effective way to prevent the damage of permanent magnet of rotor for high-speed permanent magnet motor. In this paper, the strength of NOL ring made by different winding tensions and the curing residual stress of winding composite structure were experimentally studied, in order to study on the influence of winding tension on the strength of composite material. The effects of winding tension on the material strength of composites and the residual stress of winding structure were found. The theoretical estimation method of tensile strength for filament winding materials considering the influence of winding tension and the variation law of fiber volume fraction was established. The mechanism of the influence of winding tension on the strength of composite material was found. A reference for choosing appropriate winding tension for winding composite structures was provided.

Key words: filament wound composites, winding tension, residual stress, strength
