A kind of used group mounting structure of high rigidity high-precision composite material

The invention discloses a kind of used group mounting structures of high rigidity high-precision composite material, including covering on composite material, covering under composite material, composite material rice font reinforcing rib, foam core, titanium alloy boss and titanium alloy lean on pin, the innovative composite material rice font grid reinforcement foam that uses of the invention fills sandwich main structure scheme, metalwork is locally used in used group and body connecting interface position, the program is under the high rigidity and high-precision requirement for meeting used group mounting structure, effectively mitigate mounting structure weight, 20% is no less than than traditional same type metal structure scheme loss of weight.
