| Abstract | This paper discloses methods to produce sustainable/e blends and composites based on polypropylene (PP) as viable eco-solutions for automotive interior applications. Different biomaterials based on PP were prepared, containing up to 50 wt.% of renewable content (cellulosic fibers and/or polylactide) . These biomaterials were evaluated in terms of morphology, mechanical, and thermal properties, as well as for cost and weight reductions. The /ensile strength, tensile modulus, and heat deflection temperature present at least equivalent values comparing to neat PP and to commercial PP compounds currently used in automotive interior parts . Foamed part, obtained from these biocomposites through foam injection n molding process , presented at / east similar properties as unfoamed and commercial grades while being up Io 25 wt.% lighter, 33 % Jess expensive, and 50 wt.% greener. |
