The document discusses trends in the increasing use of biocomposites and natural fibers in automotive applications. It notes that crude oil prices are expected to rise significantly in the coming decades, increasing the motivation for alternative materials. Automakers have begun incorporating bioplastics, natural fibers, and biocomposites into various interior and exterior car parts to reduce weight and emissions. Examples include Mercedes-Benz using coconut fiber and natural rubber in headrests from 1991 onward. Many automakers now use natural fibers and bioplastics in seats, door panels, and other components. Research is also exploring nano-cellulose fibers as potentially stronger and more sustainable reinforcements for biocomposites.
