Anotācija Micromechanics of novel types of fibers –composite fibers is under investigation. Fiber manufacturing technologies were analysed. Macrofibers were manufactured using monofilament microfibers: carbon fibers and glass fibers. During manufacturing four types of macrofibers were fabricated: epoxy matrix/carbon fibers with smooth surface (CF1), epoxy matrix/glass fibers with naturally uneven geometry and surface (GF1), epoxy matrix/glass fibers with smooth surface (GF2) and epoxy matrix/glass fibers with rough surface (GF3).Possibiliy of composite fiber to withstand to mechanical pulling out of concrete matrix was investigated experimentally. Single fiber pull-out sampleswere prepared. Three different concrete matrices were designed and used – low (M3), average (M2) and high strength (M1) concretes ranging from 40 to 120 MPa. Experimental results were analysed.
