Biocomposites

Definition

Biocomposites are materials made from a combination of natural fibers and a biodegradable polymer matrix. These materials leverage the benefits of both natural and synthetic components, aiming for sustainability while maintaining mechanical performance. They are significant in creating eco-friendly alternatives that can biodegrade or be recycled, fitting well within the broader concept of biodegradable and recyclable biomimetic materials.
