Manufacture and testing of fibre composite rotor components (fibre composite flywheel development program for road vehicle applications)
The manufacturing and testing portion of the flywheel development program has four main aims: (i) To evaluate flywheel manufacturing processes, (ii) To develop a full-size flywheel dynamic test capability, (iii) To develop materials data bases required for the design of flywheels, and (iv) to permit materials data correlations for different specimens/testing conditions. Manufacturing processes for composite materials have been evaluated with most of the effort concentrated on wet filament winding. Manufacturing parameters such as pot life, strand tension, strand damage and void content have been investigated for a large number of fibres and resin/hardener systems. The dynamic test facility has a high-speed evacuated chamber capable of containing and monitoring the high energy flywheel components under dynamic failure. Low speed (16,000 and 30,000 RPM) test rotors have been used to complete system proofing and to develop a drive system critical whirl frequency program. High-speed testing of the 22 in. diameter fibre composite rings is being evaluated. The basic materials data on E-Glass, S2 glass, Kevlar 49, and carbon/epoxy composites required for flywheel design have been determined from quasistatic tensile tests on ASTM longitudinal and transverse specimens and controlled strain rate hydroburst tests of 10.5 in. diameter filament wound rings. Data correlation studies are underway on the mechanical properties of ASTM flat bars (quasi-static testing), 10.5 in. diameter rings (hydroburst testing) and 22 in. diameter rings (spin testing).
