Description

Beta TX670 DISCO is a prepreg sold in sheet format. This special format allows for simpler and faster layups. Beta TX670 DISCO Prepreg has a 0°,+/-60° orientation, is quasi-isotropic within each ply, and comes with an engineered cut pattern that improves drapability.

Benefits

• Discontinuous sheets reduce layup effort and improve conformability.
• Quasi-isotropic within each ply, providing simpler and faster layup.
• Will produce consistent laminate thickness for even heat-up and meeting design targets.
• Exceptionally long out-life at room temperature of 6 months.
• Has 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.

Cure Instructions

Post Machining

Beta Prepreg Laminates
• PCD (Polycrystalline Diamond) cutting tools are recommended for post machining of Beta TX670 DISCO
laminates. Contact Airtech technical support for further information.

Notes

• Temperature measurements should be obtained with thermocouples, properly placed for accurate
temperature readings. Program controller should follow lagging thermocouple for cure and post cure.
• To avoid condensation, allow prepreg from freezer to warm to room temperature before using.
• Beta TX670 Prepreg is also available in 122 cm (48 inches) wide format without the cut pattern. Contact
Airtech for more information.
