Abstract
The present invention relates to a process for making a thin-walled composite structure having resistance profiled elements, wherein a rotational-moulding mould is made, in the shape of said structure, then resistant profiled elements made of heat-conductive material are positioned in said mould, in order to form a main resistant frame-work for said structure, after which a suitable synthetic material is introduced into the mould and the known operations of rotational moulding are carried out. The structure thus produced may be used for the construction of aerodynes, and in particular in helicopter construction.
