The most rapidly expanding application for hemp fiber is as reinforcement in composites. The blending materials range from thermoplastics such as polypropylene and polyethylene to thermoset fiber such as polyester. Plant based resins from soy, canola or corn are also used so that a 100% biocomposite is feasible. Typical applications include automotive interior substrates, furniture and other consumer products. Hemp fiber is also used to produce mineral based composites, in much the same way polypropylene or glass fiber is used to reinforce cement or plaster. The use of injection molding technology is also starting to gain ground using hemp fiber as a reinforcing material allowing hemp fiber to be used in more complex shapes and structures.
