摘要: 在复合材料缠绕成型过程中,纤维与芯模之间的摩擦滑移行为会导致发生滑线。纤维稳定缠绕的条件为设计线型的最大滑线系数小于等于纤维与芯模之间的摩擦系数,因此碳纤维与芯模之间的摩擦系数是线型设计中的重要依据。本文基于平面摩擦原理,通过滑块法,对纤维与芯模材料之间的摩擦系数进行了试验表征,并得到了压力、速率、粗糙度、树脂黏度、接触材料、纤维与运动方向所成的角度以及纤维种类对摩擦系数的影响规律。试验结果表明,压力增大、速度减小及表面粗糙度降低均会使得摩擦系数减小,黏度改变和纤维方向对摩擦系数有双重影响,会随压力与速率的改变而展现出不同的影响,而不同接触材料和纤维种类则由于表面情况的不同,有着不同的摩擦系数。

Abstract: In the process of composite winding, the frictional behavior between the fiber and mandrel can lead to slip. The condition of stable winding is that the maximum slippage coefficient of the designed fiber trajectory is less than or equal to the friction coefficient between the fiber and the mandrel, so the friction coefficient between the carbon fiber and the mandrel is an important basis in the design of the fiber trajectories. Friction experiments using a sled based on principle of plane friction are performed in order to characterization the friction coefficient. The influence patterns of normal force, velocity, roughness, resin viscosity, contact material, the angle of fiber and the direction of motion and the type of fibers on the coefficient of friction were obtained. The results show with the increase of normal force or the decrease in velocity and roughness will lead to the decrease in the coefficient of friction. A change of viscosity and fiber orientation have a double effect on the coefficient of friction, which shows different effects with the change in normal force and velocity, and different contact materials and fiber types will lead to different coefficients of friction due to the differences in the surface conditions.
