【Abstract】 Fabrication process of boron / aluminum composite tubes with longitudinal reinforcement using vapor isostatic technique is introduced in this paper,including assembly technique and hot pressing bonding methods.Three different size of B/Al composite tubes ( Φ 34 mm×1 mm×1 020 mm, Φ 40 mm×1 mm×1 020 mm, Φ 60 mm×1 mm×1 200 mm) are manufactured at (490±10)℃,under the pressure of 70 MPa for 40～45 minutes.Physical and mechanical properties of these B/Al tubes are tested,and the results show that the vapor isostatic technique is practicable and high quality B/Al structural tubes can be successfully manufactured with our parameters.更多还原
