Pultrusion is a common way to produce thermoplastic composites reinforced with different kinds of fibers. There are many different opportunities to improve the properties of a thermoplastic material. Different kind of fibers where pultruded in combination with different thermoplastic materials. The fiber content was set to 30wt% comparing the roving strain with the pultruded strain. UV-C light was used in the process to improve the fiber matrix adhesion. The pultruded strain was granulated and injection molded to specimen. The samples were tested in tensile and charpy tests. It could be shown that the concentration of oxygen on the surface of a cellulose fiber can be raised by uv light irradiation. Cellulose fibers show best changes of properties after the uv treatment.
