Experimental method for measuring interfacial shear performance of fine fiber in thermoplastic film

The invention provides a novel method for measuring the interfacial shear performance of fine fibers in a thermoplastic film. According to the method, a novel experimental method between fiber pull-out and microbead debonding experiments is provided for the first time. The experimental method comprises the following steps: firstly, manufacturing a thermoplastic film into a standard sample film; preparing a plastic mold for hot pressing; clamping the fine fibers in a two-layer plastic mold, wrapping the outer layer with a thermoplastic film, and performing hot pressing to prepare a standard sample; then carrying out a tensile test on the standard sample by using a universal testing machine to obtain the maximum load during debonding; and calculating to obtain the interfacial shear strength between the fine fiber and the thermoplastic film. The sample preparation is convenient, the test is simple and controllable, and the fiber can be kept in a vertical state in the membrane; the interfacial shear strength betw
