B180 is out-of-autoclave prepreg for the manufacture of parts operated at temperatures up to 150 °С.
—Read allВ180 is a prepreg based on epoxy resin and reinforcing filler (unidirectional tapes or fabrics of various weaving) for producing details with operating temperatures up to 150°C. Out-of-autoclave prepreg technology has the most advantages of autoclave.
The autoclave is not required for processing the prepreg B180. Curing takes place in a vacuum bag, with the technology of the package laminating slightly different from the vacuum infusion.
