Multilayered monocomposite polypropylene is a new composite material. It captures the exceptional mechanical properties of oriented polypropylene tapes in a polypropylene matrix. Low density, high stiffness, high tensile strength and outstanding impact and abrasion resistance provide the opportunity to make parts with an extraordinary performance. Due to missing reinforcement fibers like glass or carbon fibers this material is a 100% thermoplastic and totally recyclable. This paper describes the influence of manufacturing parameters (pressure, temperature, time) on semifinished material. Afterwards an exemplary vehicle application is discussed with attention to the specific advantages of this material. Hot-compacted PP has good mechanical properties. Noteworthy is the high level of elongation after fracture of up to 35%. A big advantage compared with selfreinforced extrusion molded materials is the orthotropic mechanical properties due to the fabric. The density of about 0.9 g/cm(exp3) lies well below that of glass fiber reinforced polypropylene. The material exhibited very good forming capability in thermal forming trials. Considerable forming levels could be achieved. Achievement of components with the forming levels typical for automotive construction is certainly possible. Selfreinforced plastics thus represent an interesting potential for flat body applications in automotive construction. Underbody trim is a suitable component for demonstrating the possibilities of this material. Restrictions related to the fabric structure and the possible forming process must be especially taken into account, however.
