Abstract

The purpose of the synthesis of a multi-scale hierarchical composite material was to create a material with a high specific strength, a low mass, and high strength material. To achieve this the material categorization of the Formlabs Tough V2 resin was conducted. The resin was used in the construction of a bio-mimicry diamond lattice structure. The structure was subjected to compression testing to characterize the material properties. The Tough V2 resin structure combined with cellulose created a multi-scaled material on Macro and Micro levels to show the bio-inspired design to increase the material properties in a favorable manor. The Tough V2 material degrades by time and accounts for the irregularities in this research, and this was overcame using a control sample with the final product. A control and final product were tested producing results that proved the final product had an overall increase in materials properties. An increase in specific strength of 1.75 times with average control value of 0.0495 MPa*m^3/kg to final product value of 0.0750 MPa*m^3/kg. An increase in ultimate strength and young’s modulus also occurred. Ultimate strength increased 1.75 times from 7.849MPa to 14.375MPa and Young’s modulus almost doubled at 1.8 times increase from 156.66MPa to 284.12MPa respectively.
