(4) Comparative values of the coefficient of expansion for the filament wound back-up material, aluminum and steel are given in table 2. The similarity between steel and composite bearings in the hoop direction should be noted. A higher value for thermal expansion is realized in the axial direction because of the fiberglass filament orientation. |
