Abstract

Journal of Thermoplastic Composite Materials, Ahead of Print.
This work is focused on composites based on Brewer’s spent grain (BSG), a by-product from beer production, with two thermoplastic polymers with different properties, Polylactic Acid (PLA) and Polypropylene (PP). The effects of BSG concentration were ...
