title = "Design and axial compression of composite sandwich cylinderical shells with corrugated cores",
abstract = "We present a new manufacturing technique for fabricating all composite cylindrical sandwich structures with corrugated cores. We made the entire cylindrical shell including the face sheets and corrugated core using carbon fiber woven prepreg via hot press moulding technique. The entire manufacturing process involved a two-step fabrication process with the first step used to fabricate corrugated cores in longitudinal and circumferential directions. In the next step, we fabricated the curved face sheets using curved steel mould which involved attaching a number of cylindrical face sheets to the cores to complete the fabrication of cylindrical sandwich shells. The following possible failure modes of an all-carbon sandwich cylindrical shell under axial compression are studied - (a) Euler buckling (EB), (b) Shell buckling (SB), (c) Local buckling (LB) and (d) face crushing (FC). The strain and failure mechanism were investigated in detail in our experiments. Both local buckling between bonding areas and face curshing have been found in the experiments of cylindrical shells with longitudinal corrugated cores.",
