| Product: | Biocomposite |
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.
Feedstock
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.
Pre-treatment
The retting process, carried out with warm inoculated water, has been evaluated as a potential method to modify the structure of fibers in order to prepare polymeric biocomposites.[1]
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.
