Airtech Introduces Tooling Prepreg

Airtech Advanced Materials’ Beta TX670 DISCO Prepreg combines benzoxazine resin technology with a triaxial fabric reinforcement and is said to provide benefits for tool makers building complex and high rate moulds.

The prepreg has a 0°, +/-60° orientation, is quasi-isotropic within each ply, and comes with an engineered cut pattern for improved drapability. It is sold in tile format to enable simpler and faster lay-ups.

Benefits of the new prepreg are said to include:

  • discontinuous fibres reduce layup effort and improve conformability;
  • quasi-isotropic within each ply, providing simpler and faster lay-up, and material savings through reduced scrap;
  • will produce consistent laminate thickness for less wastage and even heat up rates;
  • exceptionally long out-life at room temperature of 6 months;
  • outstanding toughness, high glass transition temperature and stability at high temperatures;
  • exceptionally low shrinkage improves tool surface quality and reduces residual laminate stresses;
  • excellent surface finish and vacuum integrity after machining;
  • very low moisture absorption in comparison to epoxy tools.
