Abstract
The composite tape winding process, which utilizes a tape winding machine and prepreg tapes, provides a promising way to improve the quality of composite products. Nevertheless, the process parameters of composite tape winding have crucial effects on the tensile strength and void content, which are closely related to the performances of the winding products. In this article, two different object values of winding products, including mechanical performance (tensile strength) and a physical property (void content), were respectively calculated. Thereafter, the paper presents an integrated methodology by combining multi-parameter relative sensitivity analysis and single-parameter sensitivity analysis to obtain the optimal intervals of the composite tape winding process. First, the global multi-parameter sensitivity analysis method was applied to investigate the sensitivity of each parameter in the tape winding processing. Then, the local single-parameter sensitivity analysis method was employed to calculate the sensitivity of a single parameter within the corresponding range. Finally, the stability and instability ranges of each parameter were distinguished. Meanwhile, the authors optimized the process parameter ranges and provided comprehensive optimized intervals of the winding parameters. The verification test validated that the optimized intervals of the process parameters were reliable and stable for winding products manufacturing.
Highlights
Composite prepreg tape winding technology is an effective way to fabricate rotationally composite materials, especially in the field of aerospace motor manufacture
In the composite tape winding process, technological parameters including heating temperature, tape tension, roller force, and winding speed are selected as independent variables; tensile strength and void content are tested separately as the evaluation index
The results show that the tensile strength of composite tape winding products is most sensitive to the variation of tape tension, sensitive to the winding speed and heating temperature, and least sensitive to roller force
Summary
Composite prepreg tape winding technology is an effective way to fabricate rotationally composite materials, especially in the field of aerospace motor manufacture. Due to the superior strength to density ratio, the prepreg tape winding process has been widely used to fabricate solid rocket motor nozzle, ablation resistance and heat protection material parts, launch tube, and special equipment for aerospace aircraft [1,2,3,4]. The prepreg tape, a woven fabric consisting of fiber and resin, can be classified by thermoset and thermoplastic matrix systems. Today’s applications are mainly manufactured with thermoset matrix systems [5]. According to the literature [5,6,7,8,9,10,11], processing parameters, such as heating temperature, tape tension, roller force, and winding speed, play a crucial role in the composite tape winding process.
