Abstract
A thermally protected and corrosion protected structure, that has in combination a core substrate and a concentric composite laminate, wherein: (i) the core substrate has a length and extends at least substantially within and is surrounded by the laminate; and (ii) the laminate has a plurality of concentric layers. The concentric layers include: (a) an inner layer of a corrosion protective material substantially along and surrounding the length of the core substrate; (b) a layer of a first protective plastic coating surrounding the corrosion protective material; (c) a layer of a heat-resistive intumescent coating surrounding the first protective plastic coating; (d) a layer of a reinforcing mesh embedded in or on the intumescent coating; and (e) an outer layer of a second protective plastic coating.
