A real-time testing method for interfacial strength of wide-temperature-range thermoplastic resin-based composite materials
By using stress-sensitive magnetic fibers and impedance models in thermoplastic resin-based composite materials, the interfacial strength can be calculated in real time, solving the problems of low efficiency and poor accuracy of traditional testing methods at different temperatures. This enables non-destructive real-time testing over a wide temperature range, improving testing efficiency and accuracy.
