Abstract
A double-cross composite fabric membrane biaxial tensile strength test piece is provided, including a core region and four cantilevers. The four cantilevers extend outwards around the core region and form a cross shape. Each cantilever is connected to the core region via an edge transition region. An end portion of the cantilever is a clamping section. The clamping section is provided with a clamping end rubber rod. The clamping end rubber rod is used for connecting to a clamp of a biaxial tensile testing machine. The clamping section is three-layered. The cantilever and the edge transition region are double-layered. The core region is single-layered. The edge transition region is in the shape of a quadrangle rounded at four corners. A manufacturing method of the test piece is also provided.
