Epoxy - AER 105P
The prepreg combines the AER 105P resin with various fabrics and comes with specific handling and processing guidelines.
Mechanical Performance Highlights (Laminates)
The resin system provides robust mechanical properties when paired with different fabric types (tested per ASTM standards):
- T300, 3K, Plain Weave Carbon: Achieves a high Tensile Strength (Warp) of 735.5 MPa and Flexural Strength (Warp) of 801 MPa under Hot Press curing. The In-Plane Shear Strength (IPSS) is strong at 109 MPa.
- T300, 3K, Twill Weave Carbon: Under Vacuum Bagging, this laminate delivers a Flexural Strength (Warp) of 768 MPa and an Inter-Laminar Shear Strength (ILSS) of 67 MPa.
- 7781, 8H Satin Weave Glass: This configuration shows good tensile properties, with a Tensile Strength (Weft) of 508 MPa and Flexural Strength (Weft) of 639 MPa.
Processing & Handling Guidelines
- Storage: The prepreg should be stored at −18°C.
- Life: It offers an excellent Shelf Life of 12 months at −18°C and maintains a long Out Life of up to 30 days at 22°C.
Recommended Cure Cycle (2 mm laminate):
- Heat Up: Ramp from Room Temperature (RT) to the cure temperature of 130°C at a rate of 2°C/min.
- Dwell: Hold the temperature at 130°C for a dwell time of 1 hour.
- Cooling: Cool down at a controlled rate of less than 1°C/min.
