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 ...

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. ...

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 ...

Progress has been made in the modeling and analysis of the single aircraft shipboard landing task. However, limitations exist in current simulations where the analysis does not include the interference arising from simultaneous operation of multiple aircraft on the same ship. To enhance the modeling and simulation of aircraft shipboard operations, especially in the case of flight safety, the inter ...

This STTR provides the Navy with a unique opportunity to fundamentally change the way ship design and analysis is accomplished by defining in Phase I the tools and computational infrastructure required to integrate selected individual specialty design and analysis tools into an overall Naval Engineering Analysis Tool (NEAT). NEAT, when mature has the potential to significantly reduce the design a ...

The objective of this research is to investigate various approaches to delivering first-principles, physics-based NVG simulation image generation for material responses and environmental effects in an affordable, deployable format to meet the needs of the various user communities. The expected outcome of this research is a deployable, affordable, physics-based NVG image generator for forward-depl ...

Unmanned Surface Vehicles (USVs) require a low signature power source for on-station operation of sensor payloads. The power source must have a high energy density, be reliable, require low maintenance, and be able to withstand salt spray and heavy seas for a two week mission duration. In addition, the payload duty cycle requires up to 25kW peak loads for ten seconds out of every minute, with cons ...

The overall objective of the project described in this proposal is to design and develop the technology for a non-lethal munition for area denial to personnel. This projectile delivers relatively the same quantity and quality of force to targets that range from just in front of the launcher to a target as far away as two kilometers. This is achieved by a carefully engineered projectile that flie ...

This SBIR project plans to develop a WDM transmitter qualified for the harsh environment of military and aerospace avionics applications. The fiber pigtailed transmitter will employ a Sampled Grating Distributed Bragg Reflector (SGDBR) InP laser to achieve a data rate of 310Gb/s. The laser will be used in conjunction with a wavelength locker to accomplish >80 wavelength channel tunability. A no ...
