TENSILE STRENGTH AT ELEVATED TEMPERATURES
TODAY MANY ENGINEERS CAN CHOOSE FROM A VARIETY OF HIGH TEMPERATURE
COMPOUNDS. A GUIDING FACTOR HAS ALWAYS BEEN TENSILE STRENGTH,
BUT NOT ALWAYS AVAILABLE ARE ELEVATED TEMPERATURE VALUES FOR THESE
COMPOSITES. MANY COMPOUNDS OFFER EXCELLENT RETENTION OF PROPERTIES
AT ROOM TEMPERATURE, BUT DROP OFF DRAMATICALLY AS THE HEAT IS
TURNED UP.
LISTED BELOW ARE A FEW OF THE MORE POPULAR COMPOUNDS USED IN ELEVATED
TEMPERATURE ENVIRONMENTS. NOTE THAT AS THE TEMPERATURE INCREASES,
THE RELATIVE TENSILE STRENGTH DECREASES. KEEP IN MIND THE RELATIVE
COST AND YOU CAN MAKE THE CORRECT COST TO PERFORMANCE CHOICE FOR
YOUR APPLICATION.
