Inventory analysis of the carbon fibres reinforced polyphenylene sulfide thermo-stamping manufacturing process

Résumé

In the context of environmental transition, the environmental impact of composite parts manufacturing has to be improved as well as the impact of each step of the life cycle. However, a lack of data makes this improvement difficult as few studies have focused on the environmental impact of the manufacturing process of composite parts by giving detailed inventory data and an associated environmental assessment. Thus, this paper aims to propose a comprehensive gate-to-gate environmental analysis of a manufacturing process used in the aerospace industry: the thermostamping of carbon fibre reinforced polyphenylene sulfide (C/PPS) composite parts. A methodology based on the life cycle assessment framework is used to quantify and analyse the environmental impact of thermo-stamping parts. First, a complete description of the manufacturing process is proposed to define the studied system boundaries. The manufacturing process is divided into unit processes representing each step of production. Linked to this description, a balance of all the consumptions and waste of materials and energy (inventory flows) is established for each unit process. As a result of the study, each inventory flow is then modelled as a function of the process parameters using data collected from laboratory-scale experimental measurements, databases, and literature. These inventory data models allow computing inventory data of different manufacturing scenarios and C/PPS composite parts. Furthermore, the gate-to-gate environmental assessment of a case study part is presented using the models developed in this paper. C/PPS over-consumption and energy consumed during heating and stamping were identified as unit processes and inventory flows contributing most to the environmental impact of part manufacturing.
