In this test, a 74mm diameter split type get-a-purkinson test device was used to impact the specimen. The relationship between the peak stress and the number of impacts, the air pressure and the thickness of FRP tube was studied by using the control variable method.The test results show that:Under the same air pressure, the elastic modulus of the specimen increases first and then decreases, and the peak stress decreases after the first impact, and then stays stable.The peak value of stress increases with the increase of air pressure. The increase of air pressure has a linear relationship with the peak value of stress.With the increase of FRP pipe thickness, the stress peak value will change greatly, and the stress peak value will increase more and more quickly with the increase of FRP pipe thickness.
