SC1078: Advanced Composite Materials for Astronomical Telescopes and Optomechanical Instruments
Advanced composite materials have been used successfully in optomechanical systems since the 1970s. They are being used increasingly in telescopes, mirrors, and other optomechanical systems. There are a significant and increasing number of spacecraft, airborne and ground-based applications. A growing array of polymer matrix-, metal matrix-, ceramic matrix- and carbon/carbon composites provide great improvements in stiffness, strength, dimensional stability, thermal conductivity and corrosion resistance over conventional materials of construction, and are considerably lighter. Low-cost, net-shape manufacturing processes make many of these materials economically attractive.
SC218: Advanced Composite Materials for Optomechanical Systems and Precision Machinery
Advanced composite materials have been used successfully in optomechanical systems since the 1970s. They are being used increasingly in numerous commercial and military applications including: optical benches, telescopes, binoculars, mirrors, metrology and photolithography equipment, and other optomechanical systems, along with thermal management and optoelectronic packaging. Numerous and growing numbers of polymer matrix-, metal matrix-, ceramic matrix- and carbon/carbon composites provide great improvements in stiffness, strength, dimensional stability, thermal conductivity and corrosion resistance over conventional materials of construction, and are considerably lighter. Low-cost, net-shape manufacturing processes make many of these materials economically attractive.
SC386: Advanced Thermal Management Materials for Optoelectronic, Microelectronic and MEMS Packaging
There are now a large and increasing number of production advanced materials designed to solve the critical problems in packaging of microelectronics, diode lasers, LEDs, displays, photovoltaics, sensors and MEMS. This course will examine materials to help alleviate issues including heat dissipation, thermal stresses, warpage, alignment, weight, size, cost, and manufacturing yield. Decades-old traditional low-coefficient-of-thermal-expansion (CTE) materials like tungsten/copper, molybdenum/copper, copper-Invar-copper, "Kovar", etc., have thermal conductivities that are no better than that of aluminum. There are now many low-density, low-CTE advanced composite and monolithic materials with much higher thermal conductivities - some as high as 1700 W/m-K - resulting in a large, increasing number of production applications. Some are cheaper than traditional materials. Weight savings as high as 85% have been demonstrated.
SC548: How To Use Composite Materials In Sensors, Structures, Robots and Thermal Management
Composite materials are widely used in sensors, optomechanical systems, aerospace structures, robots, antennas, thermal management and electronic packaging. Numerous and growing numbers of lightweight polymer matrix-, metal matrix-, ceramic matrix- and carbon/carbon composites provide dramatic improvements in stiffness, strength, dimensional stability, thermal conductivity and corrosion resistance over conventional materials of construction. Low-cost, net-shape manufacturing processes make many of these materials economically attractive.
