Abstract

Filament Winding (FW) is an automated process that allows the production of axisymmetric components in Fiber Reinforced Polymers (FRPs). As compared to traditional composites production technologies, FW enables the achievement of cost and environmental impacts reduction. In this framework, the present paper aims at developing a comprehensive model for the evaluation of process time, cost and environmental impacts of filament winding of FRP composite, at different process parameters, such as winding angle and speed, part design obtained varying mandrel length and/or mandrel diameter, and material characteristics, such as towpreg bandwidth. To this purpose, process simulations were carried out to assess the effect of process parameters and material variables on process time, material and energy use. A statistical approach was used to predict these outputs for a generic FRP component at different parameters. Furthermore, Life Cycle Assessment and Life Cycle Costing spreadsheets were developed to quantify the environmental and economic sustainability of the FRP structure. The results have proven the excellent capability of the model in predicting winding time, in particular R2, adjusted R2, Mean Squared Error (MSE) are respectively equal to 99.48 %, 99.33 %, and 0.133 min2. The relation between the process parameters and the winding time was used in spreadsheet to evaluate cost and environmental impacts of FW process of FRP structures from the early design stages, promoting a sustainable approach in the manufacturing of FRP composite sector
