The invention discloses a prepreg clamping mechanism, a friction measuring device and a friction measuring method, the prepreg clamping mechanism comprises a support frame, a clamping module, a pressurizing module and a heating module, the clamping module comprises two clamping assemblies, and each clamping assembly comprises a force application seat, a pressing frame and an elastic pre-tightening part connected between the pressing frame and the force application seat; the pressing frame is provided with a loosening abutting part abutting against the supporting frame, so that when the two stress application bases are away from each other, the pressing frame overcomes the pre-tightening elastic force to be away from the stress application bases. Under the action of the pre-tightening elastic force of the elastic pre-tightening component, the two force applying seats are driven by the pressurizing module to get close to each other and get away from each other so that the prepreg or the vacuum ...
