Problems with Biobased Composites

Biobased composites exhibit often unsatisfactory properties, such as, or resulting from (46)  

The chemical modification of a natural fiber is often performed in order to enhance the properties of the interface between fiber and matrix. A more recent method of modification, involves the deposition of a coating of nanosized cellulose onto the natural fibers or dispersing a nanosized cellulose in natural fiber reinforced composites. This method has been shown to improve the fiber-matrix interface and the overall mechanical performances. Such composites have been addressed as hierarchical, multiscale, nanoengineered, or nanostructured composites. The state-of-the-art in this field has been reviewed (46). 

Natural polymer blends and nanocomposites as well as natural fiber reinforced composites and other aspects have been reviewed in a monograph (47).
