The family of US-produced and designed URSA Fiber Thermal Interface (FTI) materials, including ALCOR AND MIZAR FTI, are high performance, flexible thermally conductive carbon-based fiber materials. Various interfaces exist between high power, heat generating components and heat sinks. Thermal management issues can come about through the minimal contact areas that arise between the two surfaces (interface) due to micro-scale surface roughness. This reduces heat conduction across the interface as air gaps have low thermal conductivity. Surface irregularity is the primary cause of thermal contact resistance. URSA products will increase contact between the two surfaces and decrease thermal interface resistance.
