Processing of biocomposites

The selection of the processing route to develop commercial use LFBC products depends upon various factors, such as (1) size and shape of the desired product; (2) thermal processing range of the biopolymers and the lignocellulosic fibers being used; (3) desired properties of the product; (4) desired production output; and (5) development cost (Singh and Chaitanya, 2015). LFBC can be processed using the traditional processing routes used to fabricate neat polymer based products. However, the addition of lig- nocellulosic fibers adds to the complexity of the process and require some modifications in tooling and processing parameters to obtain the desired defect-free products. Injection and compression molding processes are commercially viable fabrication routes for development of LFBC (Ku et al., 2011). However, prior to processing using these routes, several preprocessing techniques have been employed to improve the fiber—matrix, fiber—fiber, and fiber—matrix—tooling interactions.
