INFLUENCE OF WINDING PARAMETERS AND OF HEATING SYSTEMS WITH THERMOPLASTIC TAPE ON QUALITIES AND INTERNAL STRESSES OF A PART

APC-2/AS4 prepreg tape winding with a heated mandrel and a flame was investigated. The temperaturetime processes of these two winding methods and the influence of winding parameters on qualities and internal stresses were also analyzed. The results show that the thickness of a part wound with a heated mandrel is limited by the highest temperature of mandrel and the thickness of that wound with a flame is unlimited. Tension and the matrix content of a tape are the most important parameters for a good quality part wound with a heated mandrel.
