In order to design and manufacture more excellent space remote sensor, a new type of astronautic material — graphite fiber reinforced aluminium matrix composite (Gr/Al composite) is investigated. Several crucial technologies, such as interface reaction controls of graphite fiber and aluminum alloy, designs of fiber laminating and winding are systematically studied. Then, Gr/Al composite is successfully prepared in density of 2.12×103 kg/m3; modulus of elasticity of 129 GPa and thermal expansion coefficient of 5.0×10-6 K-1. Aiming at this composite, a set of manufacture and post-processing technology is explored in detail. Moreover,the composite is applied to design of the body tube of a space infrared remote sensor for the first time. The weight of Gr/Al composite body tube is lighter 31.8% than that of titanium alloy. Finally, the body tube preparation and assemble, lens setting and calibration, random vibration test are conducted respectively. The experimental results indicate that the first order resonance frequency of body tube component is 284 Hz(more than 100 Hz,design requirement). There is not any change for optical and mechanical system after vibration test. Accordingly, above research suggests that Gr/Al composite has important use value in space remote sensing field.
