In this paper, the flax yarn will be used as the continuous reinforcement and the Polypropylene multifilament will be used as thermoplastic resin matrix. The two things will be made into a pp/flax covered yarn, which are ready to be woven into a plain fabric. The flax/pp composite board is accomplished by hot-pressing molding. Some other composite boards are also made, whose flax yarn haven been pretreated.
