THIS PROGRAM WILL DEVELOP A NEW COMPUTER CONTROLLED STEREOLITHOGRAPHY PROCESS FOR THE MANUFACTURE OF REINFORCED CERAMIC COMPOSITE PARTS. PHASE I WILL DEMONSTRATE A WORKING SYSTEM THAT WILL DIRECTLY READ A COMPUTER CAD DRAWING OF A SIMPLE COMPONENT AND THEN GENERATE THE ACTUAL GREEN COMPOSITE PART. PHASE I WORK WILL INCLUDE DEVELOPMENT AND FABRICATION OF SYSTEM HARDWARE AND SOFTWARE, DEVELOPMENT OF ...

AstroPower is developing a two-junction monolithic tandem solar cell composed of (AlxGa1-x)0.51In.49P lattice matched to GaAs for use as the top cell in a three-junction, two-terminal tandem stack. This tunable bandgap material system is capable of current matching, at 2.03eV, in a two-junction monolithic tandem solar cell two terminal design of (AlxGa1-x)0.51In0.49P/GaAs yielding a best case pred ...

ASTROPOWER IS PROPOSING THE DEVELOPMENT OF AN ULTRA-LIGHTWEIGHT, HIGH PERFORMANCE, THIN LIGHT TRAPPING GAAS SOLAR CELL FOR ADVANCED SPACE POWER SYSTEMS. A THIN DEVICE LEADS TO HIGHER PERFORMANCE IN TERMS OF OPEN CIRCUIT VOLTAGE, RADIATION RESISTANCE, AND SPECIFIC POWER. IN A THIN DEVICE, THE INCORPORATION OF LIGHT TRAPPING TO EXTEND THE OPTICAL PATH LENGTH PERMITS GREATER CURRENT GENERATIC THAN CA ...

ASTROPOWER PROPOSES TO DEVELOP A LIGHTWEIGHT, HIGH PERFORMANCE, ULTRA-THIN ELECTROSTATICALLY BONDED GaAs SOLAR CELL WITH COPLANAR BACK CONTACTS. THE INNOVATIVE DESIGN INCORPORATES LIGHT TRAPPING, ADHESIVELESS COVER SLIDE BONDING, AND ELIMINATES GRID SHADING. THIS NOVEL DEVICE WILL EXHIBIT INCREASED EFFICIENCY AND SPECIFIC POWER DUE TO THE HIGHER OPEN CIRCUIT VOLTAGE AND SHORT CIRCUIT CURRENT OBTAI ...

A PHASE I FEASIBILITY STUDY IS PROPOSED FOR THE DEVELOPMENT OF A 2400 DEGREE KELVIN GAS SAMPLE CELL WHICH IS CAPABLE OF SIMULATING THE COMBU STION PRODUCTS OF HYDROGEN-AIR SCRAMJET PROPULSION SYSTEM AT PRESURES FROM 0.5 TO 2.0 ATMOSPHERES, FLOWS FROM 0 TO 1.0 STANDARD LITERS PERMI NUTE, AND A CELL COMPOSITION OF AIR WITH 20 PERCENT WATER VAPOR BY WEI GHT. ADDRESSED WITHIN THE PROPOSAL IS THE PRIMA ...

FIBER MATERIALS, INC. (FMI) PROPOSES A PROGRAM TO DEVELOP A NEW CLASS OF SMART MATERIALS WHICH HAVE THE CAPABILITY OF SENSING ENVIRONMENTAL CHANGE AND RESPONDING TO IT IN A DESIRED MANNER. PIEZOELECTRIC SENSORS AND ACTUATORS WILL BE COUPLED ELECTRICALLY TO FORM THE SMART MATERIAL STRUCTURE. A NEW TYPE OF COMPOSITE MATERIAL CONTAINING PIEZOELECTRIC TUBES WILL BE DEVELOPED FOR HIGH ACTUATION WITH LO ...

High surface area, super adsorbent activated carbon fibers are potentially an excellent adsorptive material for chemical protective uniforms. However, these fibers are not currently available from a domestic source. A Phase I program is proposed to demonstrate the feasibility of producing laboratory scale quantities of short highly activated carbon fibers based on a U.S. developed process (U.S. Pa ...
