Application Analysis of Titanium Alloy and Carbon Fiber Composite Tube in Recoilless Gun
In order to meet the lightweight design requirements of modern equipment,the deformation rate of a recoilless gun tube,that is the titanium alloy with carbon fiber composite tube,was measured by static hydraulic test and compared with the theoretical calculation and numerical simulation value.The error between the measured deformation rate and the theoretical calculation value is within±5%.The error between the measured deformation rate and the simulated value is within±6%.The error is acceptable.The hydraulic bursting test of carbon fiber composite tube was carried out.The results show that the safety stress and deformation rate of carbon fiber T700 and M46 are 1.874 4 GPa,1.18%and 1.465 9 GPa,0.6%,respectively.On the basis of test data,the real firing test was car-ried out.The maximum deformation rate is 0.19%,which is less than 0.6%.From the perspective of engineering application,the titanium alloy liner wrapped with carbon fiber composite tube can meet the lightweight design requirements.
