Abstract
A method of bonding plastic or polymer to a lignocellulosic material, such as wood, flax, sisal or kenaf fibers, having voids disposed across the surfaces thereof utilizes an ultrasonic radiator to induce ultrasonic vibrations throughout a mixture or layup of the material and molten plastic or polymer during formation of a resulting product, such as a wood fiber polymer composite product. To this end, molten plastic or polymer and the material are placed into contact with one another, and ultrasonic vibrations which are induced throughout the material and the molten plastic or polymer by the ultrasonic radiator urges the plastic or polymer to flow into the voids defined across the surface of the material so that when the plastic or polymer is cooled to a solid condition, the plastic or polymer is in a strong interlocked relationship with the material at the material/plastic or material/polymer interface.
