Note:
(SAM Category 1.1.4.) US Department of Defense (DoD) are increasingly challenged with demands for high-performance structural systems with attributes like superior mission readiness, lethality, and survivability to combat multifarious threats facing the nation. Attaining superior capabilities in these advanced systems requires novel approaches to design and fabrication that are enabled by robust modeling and analysis. Advanced fiber-reinforced polymer and ceramic matrix composite materials are increasingly popular for structural and engine components used in a wide variety of military applications, from combat jets, armored vehicles, to drones. Additionally, new manufacturing approaches like additive manufacturing and robotic systems like Automated Fiber Placement (AFP) for laying down composite material, offers agile manufacturing capabilities with spatially distributed material properties. This enables effective microstructure designs for optimizing local property requirements. Modeling and design of such location-specific material microstructures in structure-material ensembles is however a challenging task due to the lack of effective multiscale models for composite curing, damage, and failure. A robust approach would be to develop Integrated Computational Materials & Manufacturing Engineering (ICMME) modeling approach which can be used to model the material and its evolution over the entirety of manufacturing and service life. The key to ICMME is to have explicit representation of morphological descriptors and in-situ constituent properties at micro, meso and macro scales for composites. Hence, there is a need to accurately characterize; a) In-situ material properties under processing conditions, for example, during curing of composites. b) In-situ material and fracture characteristics under quasi-static and varying thermal conditions. c) In-situ material and fracture properties under fatigue and varying thermal conditions. d) Degradation of material due to thermal and/or chemical corrosion. The aim of this DURIP proposal is to develop a unique experimental test system to characterize in-situ thermal-chemical-mechanical properties of composite materials at micro and meso scales, to be utilized in Integrated Computational Materials & Manufacturing Engineering (ICMME). The proposal will directly address DoD’s mission towards developing advanced material and material processing systems for next generation warfighters
