摘要：
A double-cross composite fabric membrane biaxial tensile strength test piece, comprising a core region (1) and four cantilevers (2), wherein the four cantilevers (2) extend outwards around the core region (1) and form a cross shape, each cantilever is connected to the core region (1) through an edge transition region (5), the end of the cantilever is a clamping section (3), the clamping section (3) is provided with a clamping end rubber rod (4), and the clamping end rubber rod (4) is used for connecting a clamp of a biaxial tensile testing machine; and wherein the clamping section (3) is three-layered, the cantilever and the edge transition region (5) are double-layered, the core region (1) is single-layered, and the edge transition region (5) is a quadrangle rounded at four corners. A method for manufacturing the test piece is also disclosed. By means of the method, the biaxial tensile strength of the fabric film can be determined and characterized, wherein damage occurs in the single-layered test region, an
