Explain the impact of wood flour as filler on the tensile strength of a bioplastic composite.

The impact of wood flour as a filler on the tensile strength of a bioplastic composite is complex and depends on several factors. At low concentrations, wood flour can sometimes increase the tensile strength of certain bioplastics. This is because the wood flour particles can act as reinforcing agents, distributing stress more evenly throughout the composite material. The rigid wood flour particles can also hinder crack propagation, preventing the bioplastic from failing prematurely under tensile stress. H....
