A structural shell comprises a basalt fibre-reinforced material, wherein the basalt fibre-reinforced material comprises a polymer material, the polymer material being capable of at least partially thermally cracking at a temperature of from 200 to 600°C, wherein the polymer material comprises a polymethacrylate and wherein the structural shell further comprises a polymer core, balsa core or aluminium core. The structural shell is preferably part of a marine vessel, a turbine blade, a ski, a ski pole, train or tram component. The structural shells can be heated to thermally crack the polymer to facilitate recovery of the basalt fibres.
