Abstract
A method for producing natural fiber composite materials, which increases the flexural strength, thereby, making them more suitable for load bearing applications. The composite material mainly consists of natural cellulose fibers, preferably wood fibers, and olefin group of plastics and is in addition reinforced by a small amount of glass fibers which increases the flexural strength making it suitable for structural applications. A coupling agent, which increases bonding between both glass and natural fibers, with the olefin matrix is also used. The composite material can also be foamed to reduce density & cost and improve toughness, ability to accept screws/nails and surface texture.
