Award Data

High-temperature (HT) polymer matrix composites (PMCs) are desired for many aerospace and military applications. Silicon carbide (SiC) fibers provide a potentially attractive reinforcement for HT PMCs for applications ranging from propulsion systems to structures for the orbiting space plane. The sizings routinely added to commercial SiC fibers are not compatible with the new HT matrix resins. ...

New high-temperature sizings are needed to improve the properties and durability of carbon/polyimide composites. Compatibility with weaving and braiding operations and improved wetting during prepregging or resin infusing polyimide resin is also needed. Achieving these characteristics will result in reducing life cycle costs for jet engine composites through better property translation, reduced ...

The objective for this program is to increase the technical readiness level (TRL) of a Return Fuel Air Cooled (RFAC) heat exchanger (HX) based on Mezzo Technologies' proprietary microchannel technology to TRL 6 and an Oil/Fuel HX to a TRL 5. Mezzo will team with Lockheed Martin on this program. The target application for this program will be the Joint Strike Fighter (JSF).

Ceramic matrix composites (CMCs) are being targeted for many military and commercial applications due to their lightweight and high temperature stability. CMCs possess high strength, and are being investigated for use in next-generation aircraft engines. CMCs show great promise for this application, but are subject to degradation from hot corrosion, a process in which atmospheric salts combine w ...

An aqueous-based finish (sizing) was developed in Phase I to improve the carbon/vinyl ester interfacial bond. The finish is composed of a reactive coupling agent, a low viscosity vinyl ester resin, a free radical inhibitor, and a surfactant. The reactive finishes substantially improved the carbon/vinyl ester interface compared to unsized or FOE sized materials. Failure mode analysis shows that ...

The objective in this exploratory development is to design, fabricate and test a dual-mode radome for a high speed missile application. Performance, cost and ease of manufacturing will be emphasized. Radome models will be produced to be as close toflight hardware as practical. The use of an insert to provide performance enhancements will be incorporated into the design.

Commercial and government electromagnetic (EM) emission and immunity standards require testing over the frequency interval 10 kHz to 18 GHz. Currently, equipment must be tested in two or more test facilities to satisfy this requirement. The objective of the effort is the design of a relatively low cost EM test facility that has the ability to cover the full frequency interval. The full coverage fa ...

Development of adaptive, intelligent acoustic recognition/alert systems for security breaching noise detection, close proximity danger identification and perimeter protection using Safety Dynamics’ core technology, the Dynamic Synapse Neural Network (DSNN).

The goal of this STTR program is to design and demonstrate a new carburized gear steel alloy that improves performance and power density for the V22 rotorcraft transmission compared to the incumbent carburized gear steel, X53. This STTR program is a collaborative effort among materials design engineers at QuesTek, gear and drive-train engineers from Bell Helicopter, and gear testing experts from t ...
