  1. Advantages of Lightweight Composite Accumulators ROCKY MOUNTAIN SAMPE MEETING MARCH 20, 2014 Kaushik Mallick

  2. Energy Storage Devices

  3. Accumulators • Energy storage device • Dual port with at least one large port opening • Bladder inside a pressure vessel • Gas inside bladder • Hydraulic fluid outside bladder • Valves

  4. Applications • Pulsation damping (Pumps) • Blow-out preventer (Oil & Gas) • Platform stabilization (Oil & Gas) • Shock absorption (Coal crusher) • Force equilibrium (Injection molding machine) • Energy Storage for emergency (Airplanes) • Wind turbine blade pitching (Wind Energy) • Peak load sharing (Grid Energy) • Hydraulic controls (Earth Moving Equipment)

  5. How does it work?

  6. Our Market Focus • Hydraulic Hybrids

  7. Why Composite? Spherical Pressure Vessel Wall thickness, Mass, where, = Specific strength and density under which the fiber will be broken by its own weight

  8. Specific Strengths

  9. Comparison Range Acceleration
