Title: CORRUGATED COMPOSITE CYLINDER UNDER COMPRESSION LOADING
Abstract: This paper will represent the theoretical and experimental results of various corrugated composite cylinders and different materials; one of a bio-composite material, hemp, and a composite material, prepreg carbon fiber. All hemp and carbon fiber experiments will follow the same respective wet layup, autoclave process in order to avoid any discontinuities within the testing. Each material will be tested of two corrugation base shapes, circular and trapezoidal. The purpose of this experiment was to determine the most desired configuration of material type and base corrugation that results in the strongest material properties. The effect the length has on the compressive behaviors of the corrugated structures will be observed to determine the optimal sample length. The length of each specimen were varied from 38.1 to 69.85 mm for each configuration to determine the significant effect on strength. Once the desired length was determined each material and base will be applied to the cylinder. This was then applied using a two-ply sheet of material molded around a cylinder to create the hollow structure base. The corrugated panel will be formed around the cylinder to create a sandwich panel using another single sheet, creating a hollow cylinder with a corrugated core. From the results, the varying length and material of the specimen has a significant effect on the strength and failure modes under compression loading.
