Epoxy with Fiberglass wound ring (for Commutator o

Epoxy resin with fiberglass ring PROPERTIES UNIT OF MEASURE TYPICAL *Color *Resin content ( weight % ) *Glass fiber content ( weight % ) *Composit density *Circumferential tensile strength at 20°C (NOL test ) *Temperature at which the residual of Initial tensile strength is greater then 85% *Fiber diretion thermal expansion coefficient (CTE) *Thermomechanical analysis: Glass transition temperature (ASTM E 1545-93 ) % % g/cm³ Mpa (PSI) °C (°F) 1/K °C (°F) Light brown 16-23 84-77 2.10-2.20 800-1200 (116000-174000) 300°C (572°F) 8.50E-06 300-350°C (572-662°F) NOTE: Mechanical NOL data vary within a range determined by resin content and the ratio diameted thickness of the ring .This ratio gives a flexural mode that will cocur during test and test data can vary for each type of ring.
