The interface is often a limiting factor in determining the durability of composite materials used in harsh environments. Attaining a well-bonded interface is particularly difficult with low-temperature curing matrix resin systems. A need exists for a carbon fiber adhesion promoting finish that is compatible with vinyl ester chemistry. Prior work using reactive coupling agent chemistries modifi ...

The reduction of the weight of individual equipment components is one of the main objectives in the Army's quest for a lighter, more mobile force. Special attention is required for non-structural components, because the potential for weight reduction without compromising battle field survivability is greatest in this area. Optical components are usually made from glass, which has a high density ...

Asbestos insulation material has been used in shipboard environments for many years. While the material is usually safe when left undisturbed, it becomes a major health hazard during removal. The fine, needle like crystals that can be released into the air during handling are inhaled into the deep parts of the lung where they are known to cause cancer. Current removal procedures require a compl ...

New high temperature sizings are needed that are compatible with resin infusion processes to improve the properties and durability of carbon/polyimide composites. Compatibility with resin infusion processes includes compatibility with weaving and braiding operations and improved wetting with the infusing polyimide resin. Achieving these characteristics will result in reducing life cycle costs. ...

This work will extend and revise the design of the Computational Electromagnetic Framework to provide graphical user interface and pre- and post-processing capabilities to a variety of computational electromagnetic (CEM) software products for accurate and rapid design and prototyping for a variety of practical real-world DoD electromagnetic problems. Five Framework components are proposed: a mode ...

A method of determining electromagnetic susceptibility thresholds for chaotic and non-chaotic field environments is proposed. Field sets and coupled current sets are decomposed into non-chaotic and chaotic components via projection onto deterministic models of the coupled structures. Rather than assume field distributions a priori, ensembles of field data are generated from which statistical pro ...

AN EXISTING ONE-DIMENSIONAL, NON-STEADY ANALYSIS OF AN ERODING KINETIC ENERGY PENETRATOR WILL BE USED AS THE BASIS TO DEVELOP A DAMAGE ASSESSMENT MODEL. THE MODEL PRESENTLY ACCOUNTS FOR THE EFFECTS OF PENETRATOR FINENESS RATIO, COMPRESSIBILITY AND STANDING SHOCKS. IT WILL BE EXPANDED IN SCOPE BY REFINING THE PRESENT BACKFACE MODEL TO PREDICT PERFORATION AND SPALL. BECAUSE THE MODEL IS BASED ON THE ...

Intellite, Incorporated will team with the Optical Sciences Center at the University of Arizona to develop an adaptive optics system that will project a diffraction-limited spot on the retina by pre-correcting the laser beam for all significant optical aberrations of the specific eyeball under test. The system will use real-time feedback from a low-power laser reflected from the retina to measure ...

There is a requirement for compact low-cost active sensors for aided target identification in UAV operations. The mid-infrared (3-5 µm) is currently an unexploited spectral region because of the lack of frequency agile sources with narrow linewidths and high bandwidth detectors, which would be necessary in high spatial resolution laser radars. This effort will explore novel frequency agile lase ...

This SBIR Phase I project proposes the feasibility study of integrated all-optical 2R regeneration and 3R optical signal regeneration devices for use as high-speed interfaces in satellite applications (solicitation AF04-043). Currently available products achieve regeneration of signals by resorting to Optical to Electrical and then Electrical to optical conversion (OEO), which results in costly, ...
