AI Article Synopsis
- This study investigates how the spring-in phenomenon affects the assembly of carbon fiber reinforced plastic (CFRP) parts during manufacturing.
- It utilizes a coupled analysis to simulate both the forming and cooling processes in order to predict how the CFRP part will behave after being shaped.
- The predictions from a finite-element simulation of the cooling process were verified by comparing them to a physically manufactured CFRP part.
Article Abstract
The spring-in phenomenon of the composite parts can affect the assembly process. This study aims to predict the spring-in phenomenon of a carbon fiber reinforced plastic (CFRP) part. Here, we predict the spring-in of the CFRP part using a coupled analysis of the forming and cooling processes during the stamping process. First, a simulation of the entire forming process, such as the transfer of the composite laminate, gravity analysis, and forming was performed to obtain the temperature distribution of the CFRP part. Subsequently, a finite-element (FE) simulation of the cooling process was conducted to predict the spring-in phenomenon of the shaped CFRP part using the temperature data obtained in the forming simulation. Finally, a CFRP part was manufactured and compared with the results of the FE simulation.
