Composite battery housing based on (CF-)SMC/Prepreg technology
|Composite materials are becoming increasingly valued in the mobility sector due to their very high weight-specific properties. In the context of electromobility, weight-specific battery capacity has an increasing importance as an evaluation criterion for BEV. To achieve high values of >180Wh/kg, innovative lightweight solutions of the entire battery system are necessary. The battery housing needs to fulfill several requirements regarding the scenarios in the transportation industry. Besides fire resistance and crashworthiness, the assembly of the cover as well as commercially acceptable processes in terms of speed and costs need to be guaranteed.
The locally reinforced SMC process combines the high mechanical performance of unidirectional carbon fiber (CF) prepreg material in areas where needed and the design freedom of SMC (GF or CF). It is possible to integrate load introduction elements as attachment points and to use flame retardant SMC materials to fulfill required fire resistance.
