Challenge
 A major aerospace company involved in large scale government defense and
space research projects needed to develop new materials for satellites, missiles
and futuristic aircraft. They wanted to test these materials under the conditions
found in space.
They needed a test system for fatigue and crack growth studies of composite materials
at a controlled temperature between 4.2K to 273K. They also needed a system that
could handle test samples that were larger than conventional cryostats.
Solution
Instron provided a 250kN test frame with a 12-inch diameter cryostat, controlled by
an 8500 digital controller. The large cryostat could handle their largest samples.
The convenient 8500 front panel made the system easy to use. And the researchers
appreciated the efficiency of the Advanced Fatigue Crack, K1C and
J1C software programs.
