In order to design and manufacture more excellent space remote sensor
a new type astronautics material- graphite fiber reinforced aluminium matrix composite (for short Gr/Al composite) is investigated. Firstly
crucial technologies that interface reaction control of graphite fiber and aluminium alloy
design of fiber laminate and winding have been studies. Gr/Al composite has been prepared
which is destiny of 2.1210^3 Kg/m^3; modulus of elasticity of 129 GPa and thermal expansion coefficient of 5.010^-6/K. Secondly
according to this composite
a whole set of manufacture and post-processing technology has been groped in detail. Thirdly
this composite has been applied to design the body tube of space infrared remote sensor for the first time. The weight of Gr/Al composite body tube is lighter 31.8% than Titanium alloy that. Finally
the body tubes produce and integration
lenses setting and calibration
random vibration test have been achieved. Experimental results indicate that
the first order resonance frequency of body tube component is 284Hz
more than 100Hz (design requirement). Optical system does not change after vibration test. Accordingly
the Gr/Al composite has been proved with important utility value in space remote sensing field by above work.
