Abstract
Based on the requirements of the process parameters in composite filament winding, aiming at the effect of mandrel deformation and heating temperature on the distribution of winding layers in winding process, the mathematical model of winding tension was established. The analytical model of temperature-induced stress distribution in winding layers as well as the stress distribution of inner layers and mandrel under the outer pressure was investigated. Based on three typical tension winding models, the influence of the mandrel diameter ratio and taper tension coefficient on remaining tension was researched and the theoretical relationship of initial winding tension and temperature was proposed to achieve the equal remaining tension. The analytical solution was based on existing literature; while the deformation of mandrel and influence of temperature was taken into account. The results can be used for the stress analysis of curing and the design of winding tension.
