Experimental determination of non-woven bond strength distributions.

Abstract eng:
Bond fracture greatly affects the strength and damage progression of many non-wovens. Here we present a novel combined experimental and simulation approach to extract the bond strength of a particular non-woven. The approach was implemented for a commercial polyprolylene non-woven. A small non-woven specimen was imaged by micro computed tomography (µCT) and then subjected to uniaxial tensile loading through complete failure. The geometry of the non-woven was imported from the µCT data into a discrete finite element model. Using known fiber properties, the bond properties were then determined by comparing the simulated load-displacement curve with the experimental load-displacement curve. The sensitivity of the load-displacement curve to bond strength distribution will also be presented.
