A method of producing, for example, handles for using in rolling stock or other transport situations, employs a flexible core mould that is coated with an impregnated glass fibre. The coated core mould is placed into a tool for curing, whereupon the rubber core is pulled out of the center of the resulting handle member after curing. The method helps create 3D shapes of any form and cross section in a cost effective manner and using a standardized methodology and process. Further, the method enables creation of a hollow and lightweight part. The method allows use of standard glass fiber instead of more specialized braided fibre of the prior art.
