Latin Americanists and film aficionados might recognize the setting of Irma Voth and the film-within-the-novel from Silent Light (Stellet Licht), the 2007 Plattdeutsch-language film by Carlos Reygadas.
Wood-plastic composites (WPCs) are composite materials made of wood fiber / wood flour and thermoplastic(s) (includes PE, PP, PVC etc.). Chemical additives seem practically invisible (except mineral fillers and pigments, if added) in the composite structure.
Short-fiber reinforced composites are made from keratin fibers obtained from poultry feathers and polyethylenes of varying crystallinity. The chemical nature of the polymer and fiber is kept constant and the molecular architecture of the polymer is varied. It is found that low crystallinity polyethylenes are reinforced by keratin fibers but high crystallinity polyethylenes are not.
