Effect of curauá fiber content on the properties of poly(hydroxybutyrate‐co‐valerate) composites

Poly(hydroxybutyrate‐ co ‐valerate) (PHBV), a biodegradable polymer produced from a renewable microbiological source, was reinforced with varying amounts of curauá fibers (CFs). The composites were produced using a twin‐screw extrusion and injection process. Scanning electron microscopy showed poor adhesion between the matrix and fiber; however, mechanical testing showed that the addition of the fiber improved the mechanical properties....
