Overview of SpeedWave 300P Prepreg

SpeedWave 300P prepreg is an advanced composite material used in aerospace and high-performance applications. It consists of a carbon fiber reinforcement impregnated with an epoxy resin matrix. Some key features of SpeedWave 300P prepreg include:

• High strength-to-weight ratio
• Excellent fatigue and damage tolerance
• Good out-of-autoclave processability
• 180°C (356°F) cure capability
• Shelf life of 1 year at -18°C (0°F)

SpeedWave 300P is well-suited for complex, high performance composite structures thanks to its outstanding mechanical properties and processing characteristics.

Applications

SpeedWave 300P is commonly used in the following applications:

• Aircraft primary and secondary structures
• Space launch vehicles and satellites
• Motorsports and high-performance automotive components
• Industrial tooling
• Recreational products like golf clubs, hockey sticks, etc.

The excellent fatigue resistance makes it well-suited for dynamic loaded structures. The damage tolerance allows for defect tolerant design.

Processing

SpeedWave 300P can be processed using both autoclave and out-of-autoclave techniques:

• Autoclave molding – Vacuum bagging + autoclave cure provides optimal properties
• Out-of-autoclave molding – Oven cure or heated press molding also possible

Typical cure cycle is 180°C (356°F) for 120 minutes with ramp up at 2-3°C/min (3.6-5.4°F/min) and cool down at 2°C/min (3.6°F/min). Pressure ranges from 0.7 to 5 bar.

Storage and Handling

To maintain quality and achieve full shelf life, SpeedWave 300P should be stored frozen at -18°C (0°F). At this temperature, the shelf life is 12 months. Thaw cycle is typically 3 hours at room temperature before use. Care should be taken during handling to avoid damage, contamination, and moisture absorption.
