What composite material additives improve resistance to hydraulic fluid exposure?

Hydraulic fluids are essential in many industrial applications, but they can degrade materials over time. To combat this, composite material additives are used to enhance resistance and longevity. Key additives include:

1. Fluoropolymers: Known for their exceptional chemical inertness, fluoropolymers like PTFE (polytetrafluoroethylene) provide superior resistance to hydraulic fluids.

2. Glass Fibers: Reinforcing composites with glass fibers improves mechanical strength and reduces fluid absorption.

3. Aramid Fibers: These high-strength fibers offer excellent resistance to both hydraulic fluids and wear.

4. Nano-additives: Materials like graphene or carbon nanotubes enhance barrier properties, minimizing fluid penetration.

5. Stabilizers: Antioxidants and UV stabilizers prevent degradation caused by fluid exposure and environmental factors.

By incorporating these additives, composites maintain structural integrity and performance even under prolonged hydraulic fluid exposure, making them ideal for aerospace, automotive, and heavy machinery applications.
