ОоА prepreg B180



В180 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. It shows the following features and properties:

  • High mechanical performance
  • Possibility of application in loaded parts at service temperatures up to 120°C
  • Less stringent requirements for working staff
  • Glass transition temperature 154°C
  • Out of autoclave processing
