CERAMATEC HAS CONDUCTED EXPLORATORY RESEARCH AND DEVELOPMENT ON MONOLITHIC AND COMPOSITE MATERIALS IN THE ZRB2 AND TIB2 SYSTEMS AND HAS OBTAINED VERY ENCOURAGING RESULTS WITH SEVERAL PROPRIETARY COMPOSITIONS/CONSTRUCTIONS. THE AVERAGE STRENGTH OF A BASELINE TIB2 COMPOSITION WAS MEASURED AT 877 MPA (127.3 KSI). COMPOSITE STRUCTURESWITH DISCONTINUOUS REINFORCEMENT HAD STRENGTHS IN THE RANGE 400-600 ...

THE OVERALL OBJECTIVE OF THIS PROJECT IS TO DEMONSTRATE THE SUCCESSFUL FABRICATION AND DENSIFICATION OF CERAMIC MATRIX COMPOSITES FORMED BY INJECTION MOLDING. TO ACCOMPLISH THIS OBJECTIVE, A DESIGNED TEST MATRIX WILL BE DEVELOPED THAT WILL SYSTEMATICALLY INVESTIGATE THE KEY INJECTION MOLDING AND DEBINDING PARAMETERS SUCH AS BINDER COMPOSITION, SOLIDS RATIO, MOLDING CONDITIONS, DEBINDING CONDITIONS ...

IN ORDER TO USE THE NEW CERAMIC SUPERCONDUCTOR MATERIALS IN MANY APPLICATIONS, THE NORMALLY BRITTLE MATERIALS MUST BE FORMED INTO WIRES. THIS PROPOSAL SUGGESTS A WET CHEMISTRY TECHNIQUE FOR FORMING THE SUPERCONDUCTOR COMPOUND INTO A WIRE, WHICH WILL THEN BE COATED WITH A METAL JACKET TO PROTECT THE WIRE FORM PHYSICAL ABUSE AND ENVIRONMENTAL DEGRADATION. BECAUSE THE COATING PROCESS WILL BE ESSENTIA ...

CURRENT METHODS USED TO MEASURE STRAIN AT HIGH TEMPERATURES DEPEND ON UNDESIRABLE ATTACHMENTS, EXTENSIONS, OR INDENTATIONS OF THE TEST SAMPLES. THIS STUDY WILL INVESTIGATE THE USE OF NEW TECHNOLOGY TO APPLY HIGH TEMPERATURE COATING MARKS TO TEST SAMPLES. THESE APPLIED MARKS WILL ACT AS A REFERENCE OR GAUGE FOR OPTICAL STRAIN MEASUREMENT. MATERIALS INCLUDING REFRACTORY METALS AND CERAMICS WILL BE A ...

A ONE-MILLION POUND COMPRESSION REACTION LOADER IS REQUIRED TO OPERATE IN CONJUNCTION WITH THE WATERWAYS EXPERIMENT STATION 6-KBAR TRIAXIAL TEST DEVICE. TERRA TEK HAS DESIGNED AND CONSTRUCTED SIMILAR TEST SYSTEMS FOR IN-HOUSE TESTING. TERRA TEK HAS ALSO DEVELOPED UNIQUE COMPUTER CONTROL CODES SPECIFICALLY FOR ROCK MECHANICS APPLICATIONS. THE PROPOSED PHASE I EFFORT IS TO DESIGN A COMPRESSION REACT ...

THE NAVY IS DEVELOPING METHODS TO DETERMINE THE SIZE AND TYPE OF DEFECTS IN HELICOPTER GEARBOXES. WITH THIS KNOWLEDGE A BETTER UNDERSTANDING OF THE FATIGUE-CRACK PROPAGATION CHARACTERISTICS OF THE GEARS AND BEARINGS WILL BE POSSIBLE AND ENHANCE THE ACCURACY IN PREDICTING THE FATIGUE LIFE. THE PURPOSE OF THIS PROPOSAL IS TO UNDERTAKE THIS STEP BY INVESTIGATING THE THREE-DIMENSIONAL STRESS DISTRIBUT ...

It is difficult to remove oil and AFFF from voluminous streams. Research has been continously carried out to develop new technologies to be employed in this field of application with little success. Air-sparged hydrocyclone (ASH) flotation technology is a new technology developed by the University of Utah and Advanced Processing Technologies, Inc. It combines the advantages from both conventional ...

The supply of critical replacement parts to maintain the readiness of military units serving overseas can be a problem. Lone Peak Engineering (LPE) has identified an opportunity to develop a solid freeform fabrication (SFF) process to manufacture functional metal components. These metal components, prepared in a manner of hours from computer-generated models without hard tooling could be quickly ...

The efficiency, maintenance cost, and service life of off-highway vehicles can be drastically improved with the development of a heat exchanger precleaner. Development challenges include ease of integration with present and new vehicles, the device compact size, high contaminates removal efficiency, low initial and maintenance cost, and high reliability. The objective of Phase I of this project is ...

We propose developing a diode laser-based full-spectrum Raman scattering instrument prototype incorporating fiberoptic coupling for rapid, continuous on-line and remote monitoring of fuels. Raman's narrow, well-defined peaks and its insensitivity to moisture contamination allow for full-spectrum detection with 0.1% sensitivity for liquids and with 30 to 60 second response times. Traditional Raman ...
