System Could Detect Concealed Person-Borne Bombs at a Distance

The recent tragic events at the Boston Marathon illustrate the growing and critical need for the detection of person-borne improvised explosive devices (PBIEDS). Such systems, in fact, are currently under development under the guidance and supervision of the Department of Homeland Security. These sophisticated next-generation radar systems are being designed to detect bombers at long distances, in crowded areas, and even at non-fixed locations.

High-Resolution, Measurement-Based, Phase-Resolved Prediction of Ocean Wavefields

Given remote and direct physical measurements of a realistic ocean wavefield, the goal of this work was to obtain a high-resolution description of the wavefield by integrating the measurements with phase-resolved wave prediction models including realistic environmental effects such as wind forcing and wave breaking dissipation. The measurements necessary for achieving this reconstruction were guided, and the validity, accuracy, and limitations of such wavefield reconstructions were addressed.

Measuring Impact Damage to Toughened CFRP Laminates with Time Domain Reflectometry

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated CFRP structures, it is difficult to detect damage such as delamination, matrix cracks, and local fiber breakages caused by low-velocity impact loading because these damages are difficult to detect from the outside of the structure. This difficulty of inspection of the laminated CFRP structures demands the development of automatic monitoring or damage detection systems.

Testing Mechanical Properties of Polymer-Based Multi- Phase Particulate Composites

Polymer composites comprised of metallic particles distributed throughout a contiguous polymer matrix can often be modified to produce advanced composites that exhibit multifunctional characteristics. The properties of the particulate composites often depend on varying particle size, loading fractions, particle type, and the adhesion between the particulate and the matrix. Studies have shown that particle size, shape, and concentration, and properties of the constituents can affect mechanical properties. This work compared aluminum and nickel particles in PMMA thermoplastic prepared by injection molding, with the same particles in epoxy prepared in a cast-cure process.
