RESEARCH & DEVELOPMENT ACTIVITIES
Fatigue of polymer matrix composites
- Investigation of joints using a special rubber toughened epoxy
- Effects of biaxial loading in fatigue on specimens with a hole
- Fatigue of a woven glass composite with investigations on
microstructure at the unit cell level
- Effects of loading and unloading durations
- Investigation of repeated tension-torsion loadings
Development of CVT belts
- Use of composites in continuous variable transmission belts
Investigation of environmental effects
- Acid rain -- specimens immersed in synthetic acid-rain-simulating
bath and tested in fatigue -- results suggest that effect is
- Effects of vacuum, dry air and oxygen rich environment on fiber
strength -- results indicate that a pure oxygen environment
significantly decreases S2 glass strength.
- Effects of marine environment on performance -- the main aim is to
establish accelerated testing methods. Tests are in progress, pressure
being the main variable being considered.
Tension/torsion testing of tubes
- Fabricated by a wet rolling type process followed by grinding.
Tests are for marine type applications.
Automotive transmission belts
- Fatigue testing of belts reinforced with aramid layers
Dr. Fuji switched completely from ceramic matrix composites to
polymer matrix composites in the last two to three years because of
increased industrial support and because of the need to obtain
specimens. His research is heavily supported by Honda, Nitta, JSR,
Teijin, Shin Caterpillar Mitsubishi, and other companies and
organizations that lend him equipment for tests as well as fund his
research. Composite materials are supplied by courtesy of Dai-Nippon
Ink & Chemicals, Asahi Fiber Glass, Toray, and other companies.
