Description

technical field [0001] The invention relates to the technical field of quality evaluation of composite material tape-wound prepregs, in particular to an evaluation device and evaluation method for evaluating the quality consistency of composite material tape-wound prepregs. Background technique [0002] For prepregs used in composite tape winding molding, the quality consistency of prepregs cannot be well characterized according to the existing three conventional indicators, and the viscosity characterization method of prepregs has gradually been paid attention to. The viscosity of prepreg refers to the self-adhesive properties of the prepreg at the interface under the action of temperature and pressure in a very short period of time. Resin viscosity temperature curve. The composite material tape winding molding process is a process of lamination of prepreg cloth tape and winding to the mandrel without continuous fusion. It requires a certain degree of viscosity between the...
