Compounding process

Interior carpeting of a car's door made by a biocomposite of hemp fibres and polyethylene

In Biocomposite processing bio-based materials are processed to composite materials. Normally, these materials consist of a polymeric matrix that can be fossil- or bio-based. Bio-based materials fixed in this are for example wood dust, natural fibres, straws, rice husks, nutshells and others. Best-known biocomposites are Wood-Plastic-Composites (WPC) or Natural-fibre reinforced materials.

Origin and composition

Biocomposite processing is a secondary process where a composite material is formed by a matrix (resin) and a reinforcement of natural fibers or filling with other biomass-based materials like wood dust, agricultural wastes or sidestreams from food processing like nutshells or rice husks. In principal, the matrix can be a bio-based or a petro-based resin, but normally polymers like polypropylene, polyethylene or epoxys are used as matrix material.

Process and technologies

Types of biocomposites

There are several types of biocomposites on the market that normally have a fossil-based matrix with natural fibre reinforcement or wood filling. In principal also the matrix can be bio-based consisting of bio-based polymers like PLA, bio-PE, biogenic epoxis or PHAs.

Processing technologies

In the compounding process the matrix materials are melted and then mixed with fillers, plasticisers, additives and fibres to a homogeneous formulate that can be given into a screw extruder. This produces an extrudate that will be cooled down in a water bath and then cutted into composite granules. The granules can be used to produce several types of products e.g. by injection moulding or other material processing technologies.

Product

Products of Biocomposite processing are different kinds of biocomposites.
