Durable and light weight polymer composites for extreme wear conditions - Abrasive wear and scratch resistance of polymer composites
Abstract
The thermoplastic polymer compounds and polymer composites for enhanced abrasive wear resistance were developed based on commercially available polymers, compounded with micron-sized and nanosized fillers. PA1010, HDPE, UHMWPE were used as base polymers in the DURPOL compounds. Thermoplastic polyurethane (TPU) compounds with enhanced tear and scratch resistance, and glass fibre reinforced PA12 were also developed for enhanced scratch resistance. The abrasive wear of polymers was determined as mass loss during the sand abrasion tests. The tests followed the standard ASTM 65-04 concerning the overall test setup, two loading levels was used to study the wear performance of polymers in different loading conditions. For the scratch resistance evaluation, the reciprocating scratch testing was performed on VTT REC tester. The influence of the scratches on the visual appearance of the polymer surface was measured with a gloss meter and 2D profilometry. For evaluation of tear resistance of TPU materials, the specific test samples were processed by injection moulding and by stamping the sample to specific form. The samples were tested according the ISO 34-1 standard (Method B). The polymers were characterised by optical microscopy and SEM after the wear tests. The indentation measurements were used to determine the plane strain modulus, indentation modulus and indentation hardness of materials. Atomic force microscopy, DSC and DMA analysis, tensile tests and Charpy tests were also carried out for selected materials. In the cases where the polymer has no special requirements for strength or stiffness, the lowest wear can be gained with the soft elastomers. However, it was found out that when the TPUs were modified e.g. by preparing TPU-PA blends to increase the modulus, the abrasive wear of the developed material increased. Concerning the neat polymers, PA1010 exhibits lower wear compared to PEEK, and high molecular weight tube extrusion grade HDPE polymer has similar abrasive wear compared to PEEK, but the modulus of ...
