Abrasive wear performance of hygrothermally aged glass/PTFE composites

Wear of Aged Dental Composites

Surface morphology and wear characteristics of five dental composites subjected to accelerated aging were investigated. Aging conditions caused degradation of the surface as evidenced by the formation of microcracks and the exposure and loss of filler particles. Wear parameters such as track width, transition load and mode of surface failure caused by single-pass sliding were influenced by agin...

Abrasive Wear in Three-phase Waste-based Polymeric Particle Composites

Original scientific paper The experiment centres on two and three body abrasion in three-phase waste-based composite systems. The composite systems abrasion resistance is defined not only by the physical-mechanical relationships of the separate phases of the composite, but also by the mutual interaction of the phases and on the matrix-filler interface. To describe the composite system abrasion ...

Recycling of Corundum Particles - Two-body Abrasive Wear of Polymeric Composites Based on Waste

Original scientific paper Recycling of all materials should be supported by modern society. Material recycling is one of the most important ways of dealing with waste. One of material recycling possibilities is an inclusion of waste into primary matrices. A suitable ratio and a combination of waste particles influence in a positive way mechanical properties of the material in which they are dis...

Two-body and three-body abrasive wear behaviour of polyaryletherketone composites

Single and multipass two-body and three-body abrasive wear behaviour of various polyaryletherketone composites have been carried out by using a pin-on-disc machine and a rubber wheel abrasion test (RWAT) rig. Abrasive wear studies were conducted under different loads and sliding distances. Comparative wear performance of all the composites at different loads shows that specific wear rate (Ko) o...
