发明名称 Hybrid pultruded products and method for their manufacture
摘要 The present invention is a composite pultruded product and the method for its manufacture. The product is made with a plurality of longitudinal glass roving strands. In addition, a cellulosic mat is used in association with the roving. The mat serves as a filler, or reinforcing filler, to ensure uniform resin distribution within the product even when the glass content is significantly reduced. The method can be carried out on convention pultrusion equipment with little or no modification. The cellulose fiber mats may be either air laid or wet laid and should have an ultimate moisture of 3% or less before being incorporated into the pultruded product.
