Abstract:
An elongated power transmission belt in which a plurality of short aramid fibers and a plurality of non-aramid synthetic fibers are mixed into a compression rubber thereof so as to be oriented in a given direction, some of the short aramid fibers and some of the non-aramid synthetic fibers each having a protruded section extending from a surface of the compression rubber, whereinprotruded sections of the non-aramid synthetic fibers are bowed in a single direction with respect to a belt longitudinal axis, protruded sections of the short aramid fibers are bowed from a fiber root in multiple directions such that a portion of each of said protruded sections of the short aramid fibers is substantially parallel to said belt surface, and said substantially parallel portions point in multiple directions with respect to said belt axis, such that a substantial percentage of said parallel portions point in opposing directions with respect to said axis, and said protruded sections of said short aramid fibers are longer than said protruded sections of said non-aramid synthetic fibers.
