Epoxy - AER 103P

The AER 103P is a toughened, low-temperature cure epoxy resin from Azista Composites, provided as solvent-free, hot melt epoxy towpregs. It is a highly versatile material known for its good tack and drape characteristics, making it processable using methods like Autoclave, Vacuum bagging, and Compression moulding.

Key Product Properties & Applications

• Thermal Performance: The resin is formulated to achieve a moderate Glass Transition Temperature (Tg) of 159°C (318∘F).
• Cure Temperature: The required curing temperature is 130°C (266∘F).
• Density: The Cured Resin Density is 1.23 g/cc.
• Primary Applications: It is well-suited for high-performance components, including Primary aircraft structures, Helicopter blades, and Automobile structural applications.

Mechanical Performance Highlights (Selected Prepregs)

The following points illustrate the high strength achieved when AER 103P is combined with various fibers:

• T700, 12K, Carbon UD Prepreg provides the highest longitudinal strength:
  • Tensile Strength (Warp): 2,484 MPa.
  • Tensile Modulus (Warp): 138 GPa.
  • Short Beam Shear Strength (SBS): 90 MPa.
• AS4C, 3K, 5H Satin Weave Carbon Prepreg exhibits high balanced strength:
  • Tensile Strength (Warp): 775 MPa.
  • In-Plane Shear Strength: 103 MPa.
• 7781, 8H Satin Weave Glass Prepreg shows strong properties in both axes:
  • Compression Strength (Warp): 526 MPa.
  • Short Beam Shear Strength: 48 MPa.

Processing & Handling Guidelines

• Storage: It is recommended to store the prepreg at −18°C.
• Life: The material offers a Shelf life of 12 months at −18°C and a long out life of up to 45 days at 22°C.
• Cure Cycle (Autoclave):
  • Pressure: Curing requires a minimum vacuum of −720 mm of Hg.
  • Initial Heat: Ramp from Room Temperature (RT) to 100°C at 1°C/min.
  • Dwell 1: Soak for 30 minutes at 100°C, followed by the application of 5 Bar of pressure.
  • Final Cure: Ramp from 100°C to the final cure temperature of 130°C at 1°C/min, and hold for a dwell time of 1 hour.
  • Cooling: Cool down at a rate of less than 1°C/min.
