Understanding PBO Filament
PBO filament is a high-performance synthetic fiber made from polybenzoxazole. It is known for ultra-high strength and exceptional heat resistance. It outperforms many other high-performance fibers in demanding applications.
Core Properties
Ultra-high tensile strength is its standout feature. It is stronger than carbon fiber and aramid fibers by weight. This makes it ideal for applications needing maximum strength in minimal weight.
Exceptional heat resistance allows it to withstand temperatures up to 600°C (1112°F). It maintains strength at high temperatures better than most fibers. This is critical for extreme heat applications.
It offers good chemical resistance. It resists most acids, bases and organic solvents. This extends its lifespan in harsh chemical environments.
Applications
Advanced composite reinforcement uses it for aerospace and defense components. It provides exceptional strength for critical structural parts.
High-temperature insulation applications include industrial furnace components. It maintains integrity in extreme heat where other materials fail.
Protective clothing for firefighters and industrial workers uses it. It provides heat and flame protection while remaining lightweight.
Selection Factors
Confirm strength requirements. Choose the appropriate filament diameter and tensile strength rating for your application. Higher strength ratings suit more demanding loads.
Check temperature limits. Ensure it can withstand your application’s maximum temperature. Exceeding temperature limits reduces strength and lifespan.
Evaluate processing compatibility. PBO requires specific handling during composite manufacturing. Ensure your processes can accommodate its properties.
