In the composite winding process of thermal protection materials, the thickness errors of prepreg tape will result in an unstable winding process. In order to alleviate this problem, a control system is required. Therefore, a winding control system had been designed to control the stability by eliminate the winding error based on the analysis of stability winding process. The control system consists a speed controlled rotational roller. The thickness errors of the tape can be detected, and the rotational roller can be controlled to eliminate the errors and maintain the stability of winding process. Experimental results illustrate that the winding speed is converged in 30 second with a 30% initial thickness error, and winding control system could maintain the stability of winding process.
