An exterior autobody part of reinforced plastic intended to be mounted on a motor vehicle. The expression 'exterior autobody part' refers to the autobody part being entirely or partly visible when the motor vehicle is viewed from the outside. Furthermore, the invention relates to a method and an arrangement for forming such an exterior autobody part. The exterior autobody part according to the invention comprises a number of functional layers, including load-bearing layer(s) and surface layer(s), intended to provide the properties which are required for the application, and is characterized in that load-bearing layers comprise(s) fiber-reinforced thermoplastic which forms internal cavities and/or that one or several recesses has/have been created in surface layers and load-bearing layers and that surface layers and load-bearing layers together with cavities and/or recesses thereby provide a load-bearing material structure. Examples of properties essential for the application are low weight, high stiffness, and durability, recyclability and visual properties. The invention can be applied within the field of externally visible motor vehicle parts, for example boot lids and wind deflectors.
