This study intends to establish the guideline to increase the wear resistance together with the tensile modulus of polymericfibers through the addition of fillers. This has been achieved through the development of the method to determine the wearrates of fibers, the model analysis to elucidate the factors governing the wear behavior of polymeric fibers and comparison ofthe wear behavior of polymeric fibers added with various fillers with various aspect ratios. The wear rates of fibers have beendetermined by contacting the single fibers to a rotating drum covered with abrasive paper and measuring the cross-sectionarea lost by wear, taking account of the normal load applied to this point. By applying this method, the abrasive wear resistanceof polyamide 6 (PA6) fibers added with titanium carbide particles (TCP's), aluminum borate whiskers (ABW's) andvapor-grown carbon fibers (VGCF's) and poly (ethylene terephthalate) (PET) fibers added with carbon nanotubes (CNT's) with cup-stuck structure have been investigated. The addition of fillers more effectively improved wear resistance of polymericfibers as compared with the effects brought about by the drawing and the heat treatment. This result has been analyzedbased on a model with which the coefficient of friction and the wear rate have been related to the microhardness, the resistanceagainst sliding, the fracture probability and the geometry factor. ABW's and VGCF's having high aspect ratios increasedthe fracture toughness against abrasive wear. On the other hand, the fillers having a small aspect ratio exerted the rolling effectwhich has been recognized from the decrease in the resistance against sliding. The wear resistance increased more effectivelyby the addition of two kinds of fillers having different aspect ratios since two kinds of fillers exerted different effects.
