24080-638 ABSTRACT Pultruded marking devices (29,42,45,48,50,55,57,58) made of fiber reinforcement materials (10,14,16,17) embedded in a cured polyester resin matrix (65) that contains about 2% to 25% by weight of cellulose solid particulates. Unidirectional reinforcement materials (10) are the major portion of the reinforcement materials and form about 30% to 60% by weight of the total weight of the marking devices. The addition of cellulose particulates to the polyester resin formulation improves the "fill" of the resin and reinforcement package. The term "fill" means the ability of the total resin and rein- forcement package to utilize all of the available space in the pultrusion die. A package which does not exhibit good "fill" results in a cured pultruded part that has unacceptable surface imperfections, such as hollow portions similar to dents or gouges, which can range from about 1/2 inch to as much as 6 inches long in the finished article.
