Procurement of a High Strain Rate Impact Tester for Analysis of Biological Composites
Abstract
Funding is requested for a high strain rate impact test unit to enhance the AFOSR MURI program as well as enable analyses for the development of new projects. This instrument willprovide impact and fatigue testing truly at the nanoscale. The impact module allows experiments to be performed at strain rates up to 10 4 s-1, far beyond conventional indentation strain rates of ~10-1 s-1. This can be used to examine material deformation behavior in high-energy collisionsand will help in revealing structure-function related research and education in composite materials. The MicroMaterials NanoTest Vantage system with low and high load heads capable of high strain rate impact and fatigue testing in hydrated, fluid and high temperature environments will be used for dedicated, mechanical analyses of bulk composites (includingbiological, biomimetic and traditional composites). The equipment will greatly enhance the PI’s contribution to MURI (FA9550-15-1-0009) and AFOSR (FA9550-12-1-0249) projects on the investigation of structural elements on strengthening and toughening in impact and abrasion resistant biological composite materials. Additional projects are being created that investigate structure-property relationships of nanomaterials to develop energy conversion and storage systems. The system will enhance undergraduate students’ interest and understanding in materials science by facilitating research opportunities. This will take place in conjunction with the interdisciplinary degree program in Materials Science and Engineering at UCR, an accredited Hispanic Serving Institution (HSI) and one of America’s most diverse research-intensive universities. This support will contribute to the PI’s unique program, which conducts both experimental research on synthesis-structure-property relationships in impact and abrasion resistant biological and biomimetic composites and on biologically inspired synthesis of nanostructural materials.
