Influence Mechanism and Optimization Analysis of Technological Parameters for the Composite Prepreg Tape Winding Process

Abstract

Composite prepreg tape winding technology has proven to be an effective method for manufacturing revolving body composite structures in aerospace field. Process parameters including heating temperature, tape tension and roller pressure have an important impact on the winding products’ mechanical property such as tensile strength. The aim of this study is to investigate the influence mechanism and optimization analysis of parameters for the composite prepreg tape winding process. Firstly, the sensitivity analysis for single parameter had be employed to reveal the influence mechanism of each winding parameter change on tensile strength. Secondly, iso-surfaces analysis for parameter range had be applied to describe the distribution law of parameter with continuous distribution characteristics. Then the coupling analysis for process parameters was carried out employing response surface methodology. The analysis results showed that tape tension has the most significant effect on the winding products’ tensile strength. And the outstanding parameter combination with the heating temperature of 72 °C, tape tension of 307 N and roller pressure of 1263 N was provided by response surface design software via desirability function method. The validation experiments showed that the optimal parameter combination has a positive guiding significance for improving the quality of winding products.

New Advances and Future Possibilities in Forming Technology of Hybrid Metal–Polymer Composites Used in Aerospace Applications

“…[355][356][357]. Circumferential, helical and planetary winding [358][359][360][361] can be performed depending on the direction of rotation of the core and the way the carriage is moved. The design of the carriage with roving and the core turning device enables both the carriage speed and rotational speed of the core to be changed, so that the winding angle can be adjusted.…”

Predicting and Improving Interlaminar Bonding Uniformity during the Robotic Fiber Steering Process

“…However, the high processing cost hinders composite materials being widely used [ 4 ]. Winding technology and automated placement technology are common technologies for fabricating composite products with low cost [ 5 , 6 , 7 , 8 ]. As a key branch of low-cost composite processing technologies, robotic fiber placement (RFP) technology provides several advantages for the fabrication of composite components with complex surfaces, including real-time process parameter control [ 9 ], low rejection rates and large layup angles [ 10 ].…”

Reliability Analysis of Tape Winding Hydraulic System Based on Continuous-Time T-S Dynamic Fault Tree

“…As a key technology in tape winding, the pressure system is applied to the tape to enhance the bonding between the layers of the tape and remove the bubbles, improve the bonding strength between the tape layer and the density of products, and prevent layer fold and slip effect, to improve the strength of the products. Among them, too little pressure will lead to the tape and the laminated plate cannot reach the close bonding state, which affects the mutual penetration of the polymer chain; excessive pressure will extrude the collective in the molten state from the laminate, resulting in the phenomenon of poor glue [2], which cannot ensure the good adhesion of the tape belt because the working environment of the tape winding needs a certain temperature to ensure that the impregnation will not solidify in advance to maintain the viscous state. It also provides stable pressure to maintain the tightness of the winding process.…”
