THE EFFECT OF COMPRESSION ON THE TENACITY OF HIGH-PERFORMANCE FIBERS
This work gives an overview of the axial and transverse compressive behavior of aramid and ultra-high molecular weight polyethylene (UHMWPE) fibers. Literature and own work are compared for different (combined) load cases at filament and yarn level. The micro-compression, elastica loop, four-point bending and recoil tests are different methods to quantify the axial compressive strength of individual filaments. A parallel plate experiment aims to quantify the transverse compressive filament strength. The pin-plate and pin-loop experiments assess transverse and compressive properties on the yarn level.
