Abstract
Štúdie opotrebenia horolezeckého lana sú dôležité pre zvýšenie bezpečnosti lezenia. Táto práca sleduje opotrebenie spôsobené trením lana vo vratnom bode pri istení a spúšťaní lezca. Zisťovala sa miera opotrebenia na povrchu lana vplyvom trenia. Na meranie sa použil počítač so softwarem obrazovej analýzy Lucia G. Ďalej sa skúšali termomechanické vlastnosti na prístroji TMA. Pevnostné charakteristiky - pevnosť a ťažnosť sa skúšali na trhacom prístroji. Porovnávali sa pevnostné charakteristiky opletu z lana nového a starého, ďalej pevnostné charakteristiky priadzi z jadra a opletu lana nového a starého.
Study of climbing rope wear is an important part of climbing material control aimed to increase the climbing equipment safety. This study evaluates the wear caused by climbing rope friction in belaying point due to belay of climber. First the wear of rope surface has been observed with the use of computer aided image analysis Lucia G. The thermomechanical properties of rope sheath has been tested with TMA CX03R device. The mechanical properties of sheath and core yarns - strength and elongation to fracture - have been tested with dynamometer TIRATEST 2150. The change of worn rope properties have been evaluted in comparison to the properties of the new one
