Use of Bio-Based and Renewable Raw Materials in SMC

Within this research project, both fillers and resin systems were replaced by bio-based counterparts.

In the research project BioSMC, new fields of applications were opened up by using bio-based and renewable raw materials in SMC semi-finished products. Conventional glass fiber reinforced SMC semi-finished products usually consist of approx. 15–25 wt.-% of unsaturated polyester resin including anti-shrinkage additives, approx. 7 wt.-% of application specific additives, approx. 40 wt.-% of mineral fillers (e.g. calcium carbonate) and approx. 20–35 wt.-% of reinforcement fibers with a length of 25.4 mm. By replacing resin, fillers and reinforcement fibers with bio-based components, the aim was to develop new SMC semi-finished products, which are processible under conventional SMC manufacturing and processing parameters, also show significantly reduced density compared to conventional SMC and provide the same absolute mechanical properties.
