Investigation into Failure in Mining Wire Ropes—Effect of Crystallinity

Abstract: A range of blends of polypropylene-polyethylene are investigated for their mechanical performances. These speciality polymer blends are chemically designed to suit high modulus/high load bearing mining wire rope applications subjected to continued bending and tensile stresses and fluctuating loads and are exposed to extreme weather conditions. In this paper we study the influence of different parameters on the performance of the wire ropes: chemistry of polymer, crystallinity of the polymer matrix, and the mor… Show more

“…The surface chemical composition of the non-modified PP, BHA-TBAEMA, and PP modified with BHA-TBAEMA were analyzed and FTIR spectra were displayed in Figure 8 . The characteristic peaks of the non-modified PP were visible at 2951, 2915, 2837, 1455 and 1375 cm −1 , which are typical alkane (C–H) peaks [ 37 ]. On the other hand, the modified PP showed new peaks that were assigned to the C–H at 2915 and 2850 cm −1 , C=O ester group at 1733 cm −1 , and C–O–C asymmetric stretching peak at 1160 cm −1 .…”
