METHOD FOR OBTAINING THERMOPLASTIC COMPOSITE STRUCTURES AND PREPREG TAPE USED BETWEEN THEM Russian patent published in 2021 - IPC C08J5/00 B29C65/02 B29C65/44 B32B27/08 B29C70/40 

FIELD: metallurgy.

SUBSTANCE: group of inventions relates to a method for obtaining a thermoplastic composite preform, to a thermoplastic composite tape, and to a thermoplastic composite preform. The method for obtaining the thermoplastic composite preform includes assembling a package of composite layers of high-melting thermoplastics; introducing low-melting thermoplastics between composite layers; and bonding composite layers of high-melting thermoplastics with each other by melting low-melting thermoplastics. Package assembly includes laying stripes of high-melting thermoplastic composite prepreg having low-melting thermoplastics on the surface. Introduction of low-melting thermoplastics includes applying particles of low-melting thermoplastics on the surface of each layer.

EFFECT: group of inventions provides for an increase in physical and mechanical properties of obtained products.
