Increasing fuel efficiency standards for automobiles has driven choices by automanufacturers to downsize and boost internal combustion engines by turbocharging or supercharging to optimise performance per fuel comsumption. This paper will examine the failure modes and limitation for use of aramid yarn products for knitted hose applications. Modes discussed are compression and abrasion and related failures in Kevlar para-aramid differences to modes of Nomex meta-aramid failures as they relate to knitted reinforcements for hose.
