This is another common question, as many of our customers require thermal straps for optical and sensor systems mounted on aircraft and vehicles. While TAI's graphite based thermal straps have been extensively qualified by NASA, ESA, JAXA, the DLR, and many more, the shock and vibe profiles tested were only meant to survive launch. If your application will subject a strap to significant lifetime shock and vibration (some military aircraft and tanks, for example), or thousands/hundreds of thousands of deflection cycles (or a wide range of motion), we do not have ample test data to guarantee a graphite strap may survive the operating conditions, and will typically recommend a metallic thermal strap like our CuTS products.
