The Mechanical and Tribological Properties of Epoxy-Based Composites Filled with Manganese-Containing Waste

Abstract

Waste from large-scale production processes is a growing environmental problem that can potentially be solved by using this waste as fillers in polymeric composites to improve the mechanical and tribological properties of polymeric matrixes. This paper presents research concerning how the introduction of fillers in the form of manganese residue and manganese(II) oxide changes the mechanical and tribological properties of epoxy composites produced by gravity casting. The research was carried out for composites with 2.5 wt.%, 5 wt.%, and 10 wt.% of fillers. Properties such as the density, hardness, resilience, flexural strength, deflection, flexural modulus, tensile strength, elongation at break, and Young’s modulus were determined. Moreover, based on the ball-on-plate test, the wear volume and friction coefficients of the tested materials were determined. Microscopic images of the abrasion profiles were also obtained. The geometry of the wear paths was measured with a profilometer, and the results showed that introducing fillers reduced the abrasive wear of the composites; however, in all cases, the fillers decreased the strength of the tested materials.

Influence of Graphite as a Filler on Selected Mechanical and Structural Properties of Layered Composites with Polyester-Glass Recyclate

“…Recykling mechaniczny jest najprostszy, najmniej kosztowny i najbardziej rozpowszechniony. Polega on na przetwarzaniu zużytych materiałów w procesach fizycznych (rozdrabnianie, mielenie, klasyfikacja), w wyniku czego powstaje recyklat, który można ponownie wykorzystać do wytworzenia produktów o właściwościach użytkowych [9,16].…”

“…The mechanical blade is the simplest, least expensive and most widespread. It consists in the processing of used materials in physical processes (grinding, grinding, classification), resulting in the formation of a recyclate that can be reused to produce products with functional properties [9,16].…”

Acoustic Emission and K-S Metric Entropy as Methods to Analyze the Influence of Gamma-Aluminum Oxide Nanopowder on the Destruction Process of GFRP Composite Materials

“…Due to the continuous search for materials that can improve the mechanical properties of composites [19][20][21], in this article it was decided to test composites based on glass fibers (GFRP) with the addition of the gamma-aluminum oxide nanopowder nanofiller. In order to more precisely visualize the results and determine the impact of the nanoadditive on the destruction process of composite materials, tools such as the acoustic emission method and K-S metric entropy were used for analysis [22].…”

Influence of Citrus Fruit Waste Filler on the Physical Properties of Silicone-Based Composites

“…The Silesian University of Technology research using silicones as the composite matrices resulted in several results in which composites with organic and non-organic filling were tested. The study used inorganic zinc and manganese wastes from the steel industry as fillers in silicone-based composites [42,43].…”
