Abstract
In the process of composite resin prepreg tape winding, the presence of pores or voids among the layers of composite can result in reduced strength of winding. To alleviate this problem, it is required that the composite tape winding machines be designed such that the layers of composite are evenly wound on the previous one. The paper presents a novel design of flexible winding system for composite tape winding. Based on the analysis of errors in winding process, the novel winding system eliminates winding point error and winding angle error based on the speed controlled flexible roller. This paper also presents the kinetic analysis of the novel system and its controller design. Experiments are conducted on the novel winding system. The experimental results illustrate that the novel flexible winding system has a good performance in winding accuracy.
Highlights
Composites have been widely used in aerospace engineering and other fields for their advantages like high specific strength, high specific modulus, good thermal stability, and good high temperature performance
In order to decrease the pores, Costa et al showed the influence of the porosity in carbon fiber/epoxy resin and carbon fiber/bismaleimide resin composites on material performance [8]; Madsen and Lilholt built a theoretical model for the effect of pore phenomenon on unidirectional fiber composite performance [9]; Koushyar et al focused on the phenomenon of carbon fiber/epoxy prepreg growing under hot pressing and vacuum [10]

Summary
Composites have been widely used in aerospace engineering and other fields for their advantages like high specific strength, high specific modulus, good thermal stability, and good high temperature performance. Tape winding is a major method to manufacture the nozzle of rocket motors [1]. The resin prepreg tape was deposited by a compaction roller during composite winding process [2, 3]. During the process, the tape would be deformed by the compaction force [2]. The pores or voids between winding layers are inevitable which will result in poor dispersion of materials and affect the overall performance of the composite component. In order to decrease the pores, Costa et al showed the influence of the porosity in carbon fiber/epoxy resin and carbon fiber/bismaleimide resin composites on material performance [8]; Madsen and Lilholt built a theoretical model for the effect of pore phenomenon on unidirectional fiber composite performance [9]; Koushyar et al focused on the phenomenon of carbon fiber/epoxy prepreg growing under hot pressing and vacuum [10]
