A -- FY95 ARL BAA AMENDED SYNOPSIS SOL DAAL01-95-R-ARL SOL DAAL01-95-R-ARL POC POC: Karen Wishnow, ARL BAA Coordinator (301) 394-3690. This synopsis modifies the synopsis previously published on 05/05/94. This amendment will be available on the ARL Mosaic Server (http://info.arl.mil:80/) or via anonymous ftp from ftp.arl.mil in directory /arl/baa. The Army Research Laboratory has identified an additional research topic 5.2 COMPOSITE MATERIALS. Proposals are requested involving fundamental and applied research of materials issues of polymer-, metal-, and ceramic-matrix composites and their hybrids and at extending theory and experimental methodology where current theory and techniques are not adequate for modeling, analyzing or characterizing the synthesis, processing, microstructure, and properties of such advanced materials and material systems. The broad areas of interest include such issues as dissimilar material bonding and adhesion, interpenetrating networks, TS-TP adherend interfaces, multilayer composites, hybrid fiber systems; synthesis and thermochemical and mechanical analysis of constituent material forms; surface analysis techniques; energetic and chemical interphase/interface development/properties; cure behavior and modeling; transport and degradation properties including thermal, oxidative, electrical, and chemical; effects of additives and fiber treatments on formation and properties of the fiber-matrix and hybrid system interphase/interface; failure modeling and analysis; special thermoplastic composite issues including intimate contact and healing mechanisms and modeling; interactions of composite and hybrid systems with electromagnetic and radiative fields; modeling/analysis of void formation and effects of voids and other defects on strength, modulus, microcracking, etc,; composite-specific testing and analysis technique development and utilization including mechanical and electromagnetic property tests, fiber and matrix property tests, environmental exposure tests, etc.; statistical analysis of composite properties; assessment and analysis of industry-reported composite material property data; fundamental concerns and mechanisms for novel curing including electron beam, dielectric, microwave, etc.; physical property analysis; hygrothermal effects testing and analysis; and oxidative stability; impact and delamination resistance; visoelastic effects; analysis of process-induced properties; micro- and macromechanical analysis of fracture, buckling, delamination, etc.; mechanics of laminated forms; numerical analysis; material durability and performance; fundamental research in new material developments including fiber forms and surface modifications, low-density core materials, low-viscosity thermosetting resins, processable phenolic resins, etc. Special emphasis should be placed on composite materials supporting personal and vehicular armor; low observable, and lightweight, multi-functional materials for aircraft, ground vehicles, and soldier systems; and on the characterization of polymer/hybrid materials surfaces and interphase phenomena, adhesive bonding, durability/life extension, and smart/intelligent material systems. Reporting of scientific results and conclusions may be incorporated into scientific meetings and publications including general literature (conference proceedings, journals, etc.), technical reports (DTIC, ARL Tech Reports, etc.), and standardization documents (ASTM, MIL-HDBK 17, etc.).
