Manufacturing and Testing of a Sandwich Cylinder with Pyramidal Truss Cores

摘要：

A new method for fabricating composite sandwich structures with a pyramidal truss core has been proposed. The sandwich structure was assembled with two laminate face-sheets and a composite truss core. Axial compression was carried out to reveal the stiffness and load capacity of the fabricated sandwich cylinder. Compared with the stiffened cylinder with similar dimensions and mass, the sandwich cylinder is shown to be stiffer and stronger by several times. The experimental results indicated that skin crippling was observed in the testing to be the dominating failure mechanisms of the pyramidal truss sandwich cylinder. The novel sandwich structure shows the promise of truss composites in upgrading the mechanical properties.
