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 ...

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 ...

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. ...

During aircraft turbine engine operation, augmentor (afterburner) operation is often associated with combustion instabilities (oscillations) that can be potentially detrimental to the turbine engine if the resonant amplitude levels are excessive.Oscillation in the frequency range of 50-100 Hz is commonly called

This subtopic solicited Phase I R&D for an advanced Fourier transform infrared (FT-IR) system that would provide fast-scanning high resolution (3 scans/sec at 1cm-1 resolution), low noise, mid-infrared measurements for characterization of spray flames. In Phase I, Advanced Fuel Research, Inc. (AFR) demonstrated FT-IR emission/transmission (E/T) measurements from the NIST spray combustion faci ...

AgilOptics’ Phase I SBIR proposed the development of a moire¢ Wave-Front Sensor (MWFS) test-bed to evaluate the MWFS design developed and patented by the University of New Mexico (UNM) and to extend the design for use in a closed-loop Adaptive Optic (AO) system with a Micro-Electro-Mechanical System (MEMS) Deformable Mirror (DM) corrector. Our Phase I results have shown that the MWFS provides i ...

Under SBIR Topic N04-218, Applied Physical Sciences Corp. (APS) developed and demonstrated candidate modifications to the existing DD(X) Integrated Undersea Warfare System’s High Frequency (IUWS-HF) bow sonar signal processor that would improve the sonar’s mine-hunting capabilities in refractive, multipath environments. In Phase I, we derived a localization algorithm that correlates measured ...

Sterile and pyrogen-free water for injection (WFI) is an essential ingredient in parenteral and blood products. Applied Research Associates recently demonstrated a novel thermal approach that can achieve fast and virtually complete sterilization anddepyrogenation of potable water, and eliminate the possibility of bacteria and pyrogen buildup within the water conversion system (Navy STTR N99-T008 ...

The proposed effort is to develop a frequency and waveshape agile pulse forming system. The pulse forming system is based on a Blumlein topology and allows a wide range of waveforms to be generated from a fixed set of mechanical hardware.

The advancement of shock mitigation technology is critical to the protection of fuzes in future penetrating weapons that are smaller and faster than current weapons. The first objective of this project during Phase II is to continue the research anddevelopment of three shock mitigation approaches, and apply them to develop a mount or housing that protects the most susceptible component of a fuze, ...
