Overmoulding a profile for producing a shaped article, a shaped article obtained therefrom and use thereof

A method for producing a shaped article (100), said method comprising at least the steps of:

• (A) pultruding or extruding a fiber reinforced polyurethane in a die to obtain a first element (10), said die comprising a plurality of first surface features,
• wherein the first element (10) comprises an outer surface (11), said outer surface (11) comprising a plurality of second surface features (12) formed by the plurality of first surface features in the die,
• (B) injection molding a second element (20) onto the first element (10) to obtain the shaped article (100), wherein the second element (20) comprises an outer surface (21), said outer surface (21) comprising a plurality of third surface features (22),
• wherein the first element (10) positively locks the second element (20) such that each of the second surface features (12) completely overlap with each of the third surface features (22).

A shaped article (100) obtained by a method of producing a shaped article (100), said method comprising at least the steps of:
