Abstract
A friction segmented brake disk has a plurality of arcual segments which are rigidly fastened together by a tongue extending from at least one end portion of the segment and is received by an adjacent segment recess and fastened thereto by at least two fastening members. The tongue, recess, and fastening members all reside by the periphery of each arcual segment, substantially beyond the swept area of each segment to avoid the thermal expansion and contraction forces inherent to the swept area. In another embodiment, a rigid friction brake disk contains a plurality of arcual segments which have a slot in each end portion thereof. A clip engages the slots and is connected thereto by a fastening member. Similarly, the clip, slot and fastening members will reside on the periphery of each arcual segment, substantially beyond or outside the swept area of each segment, and thereby also minimizes thermal expansion and contraction forces inherent to the swept area.
