    The non-asbestos organic friction materials with various abrasives such as Zr02, ZrSi04, Al203, Fe30 4 were manufactured and
    underwent friction tests to find conditions for transfer film formation and their effect on friction coefficients, and also the effect of
    different abrasive components was analyzed Friction tests were composed of the effectiveness test and the fade & recovery test
    successively and counterpart disks were examined at each stage to find transfer film distribution changes. Friction surface observation
    by SEM revealed that the transfer film was formed not in the effectiveness stage which simulated the normal braking condition, but
    in the fade stage when temperature rose up to 6000C. The level of friction coefficients for most friction materials turned out to be
    opposite to the quantity of transfer film formation implying that the transfer film reduced the friction coefficient. High temperature
    condition was requisite for transfer film generation, but the transfer film was hardly formed irrespective of the magnitude of
    deceleration rate under moderate operating conditions where temperature stayed below 350°C. Among the friction materials tested,
    friction material which contained Al20 3 produced the least transfer film but showed the highest friction coefficient throughout the
    entire stages of the friction test.
