Biocomposites

Definition

Biocomposites are materials composed of a matrix made from biopolymers, such as plant-based materials, combined with natural fibers or fillers. These materials leverage renewable resources to enhance mechanical properties while minimizing environmental impact. Biocomposites are increasingly recognized for their potential in various applications, offering a sustainable alternative to traditional composites that rely on petroleum-based products.
