Title Strain Field Analysis and Kinetics of Crack Propagation of Binary Triblock Copolymer Blends
Date 30.03.2006
Number 13522
Abstract <B>Summary:</B> The crack toughness behaviour of binary styrene-butadiene (SB) triblock copolymer blends of a thermoplastic block copolymer (LN3) and a thermoplastic elastomer (LN4) with different molecular architecture was studied using essential work of fracture (EWF) concept and was correlated to the morphological features from transmission electron microscopy (TEM). An increase in the crack toughness behaviour between 60 and 80 wt.-% LN3 has been observed and is attributed to a change from cylindrical to lamellar morphology. The time-resolved crack propagation studies have offered new dimensions to understand the kinetic aspects of fracture behaviour while the strain field analysis has explained the time-dependent deformation behaviour to characterise the time dependence of the strain energy dissipation modes.
