Abstract:

The PIs used the funds from award number W911NF1510353 to purchase an Instron E-3000 ElectroPuls tensile tester. This instrument complements existing tensile analysis instrumentation by expanding our capabilities to include low loads. High performance lightweight composite materials address many of our nations critical technological challenges including defense systems, sensors, personal protection and armor, vehicle components, and water security. This potential impact is attributed to the careful design, characterization, and modeling of composite properties and performance. Our research efforts engineer novel composites that enable a nanoscale understanding of composite matrix failure modes, and thus, direct the assembly of enhanced high performance heterogeneous materials. Although the final composite materials have a high modulus and are resilient, analyzing a full range of crosslinking densities within the polymeric matrix further develops structure-property relationships and demands access to low modulus tensile testing. Moreover, analyzing the effects of environmental conditions, such as temperature, on stochastic model development requires experimental characterization tools that can perform thermomechanical testing on composites with varying moduli. Developing materials for damage detection in polymer matrix composites by using smart composite particles necessitates static and dynamic fatigue testing at low loads, and the information gathered has enabled next generation composite fabrication and implementation.
