A method and system for the production of fibers for use in biocomposites is provided that includes the ability to use both retted and unretted straw, that keeps the molecular structure of the fibers intact by subjecting the fibers to minimal stress, that maximizes the fiber's aspect ratio, that maximizes the strength of the fibers, and that minimizes time and energy inputs, along with maintaining the fibers in good condition for bonding to the polymer(s) used with the fibers to form the biocomposite material. This consequently increases the functionality of the biocomposites produced (i.e. reinforcement, sound absorption, light weight, heat capacity, etc.), increasing their marketability. Additionally, as the disclosed method does not damage the fibers, oilseed flax straw, as well as all types of fibrous materials (i.e. fiber flax, banana, jute, industrial hemp, sisal, coir) etc., can be processed in bio composite materials.
