The invention discloses a method for detecting the performance of an aerostat capsule material. The method comprises the following steps of: processing the capsule material to obtain a plurality of flaps with the same size, and splicing and thermally sealing the flaps to form a spherical capsule; connecting the ball bag body with pressure measurement and control equipment, and inflating air into the ball bag body to test the pressure resistance of the bag body material; connecting the ball bag body into temperature acquisition equipment and pressure acquisition equipment, and filling helium into the ball bag body; collecting and recording a temperature value and a pressure value, and detecting the air tightness of the ball bag body by analyzing the collected values. According to the invention, the processing of an actual sphere can be simulated, the manufacturability of a material in an actual manufacturing process is verified by using damage, the verification from linear heat sealingto curve and curved surfa
