Measurement Analysis for Increasing Resource Efficiency during Autoclave Processes for the Production of Fiber Composites

Abstract

Fiber-reinforced plastics are known as outstanding lightweight composite material, which are used in various areas. Especially the demand for components made of carbon fiber reinforced plastics (CFRP) has steadily increased within the last years due to their high strength and stiffness combined with light weight. The manufacturing of CFRP components is a cost-intensive and time-consuming process due to frequently required and challenging manual operations for several working steps. In order to remain competitive and meet the small-batch production because of increasing desire for individuality and diversity, the manufacturing process of CFRP components needs further development. In order to face these challenges, this paper focuses on the resource efficiency of curing processes with the autoclave technology. The measurement analysis of the different energy consumers of the autoclave at changing the curing parameters (temperature, pressure, time) shows how the settings affect the resource efficiency of curing processes. Finally, the authors present their recommendation for action in order to increase resource efficiency.
