Technical FAQ: Satellite Thermal Management
Q: What thermal conductivity specifications are critical for LEO satellite assemblies?
A: LEO satellites require materials with >1000 W/m·K in-plane conductivity to manage rapid thermal cycling between sun exposure and eclipse periods. Our film provides 1700 W/m·K isotropic thermal transfer.
Q: How does the thermal expansion coefficient affect satellite assembly reliability?
A: Mismatched CTE between components induces mechanical stress during thermal cycling. Our graphite film has CTE of -1.5 ppm/K, minimizing thermal stress at interfaces.
Q: What international standards apply to thermal interface materials in aerospace?
A: Key standards include ECSS-Q-ST-70-36C for thermal control materials and MIL-STD-1540E for satellite thermal testing protocols. Our materials exceed requirements for outgassing (TML
Q: Are there mass restrictions for thermal systems in GEO satellite platform designs?
A: Thermal systems typically must be
Q: How does EMI shielding impact thermal material selection?
A: Many thermal materials increase EMI vulnerability. Our graphite film provides dual EMI suppression and thermal management without additional RF shielding layers.
Q: What surface preparation is required before applying thermal interface materials?
A: Surfaces must achieve 32-125 μin Ra roughness and be cleaned with isopropyl alcohol. Our film includes pressure-sensitive adhesive backing for simplified installation.
Q: How do radiation tolerance requirements affect material choices for satellite assemblies?
A: Materials must withstand >100 krad TID in GEO applications. Our graphite demonstrates performance retention at 300 krad with minimal degradation.
