Research Studies of Wear Behaviour and its Parameter Evaluations on PMMA-B4C Composites

Abstract

In contemporary times, the field of composite materials comprises a wide range of uses. Various industries are actively seeking ecologically responsible alternatives that, due to their robust composition and greater endurance, can outperform conventional materials. This pursuit is especially evident in the automobile, marine, and aerospace industries. In this regard, our research focuses on a unique hybrid composite that combines PMMA as the foundational substrate with increased B₄C reinforcements. The hand layup technique is used in the fabrication process, which was chosen as the methodology for composite synthesis in this investigation.A full battery of mechanical evaluations, including flexural hardness, tensile compression, and others, was meticulously carried out. Notably, our focus is on the investigation of wear behavior, which has resulted in the development of these hybrid composites. Dry sliding circumstances were used to test the durability of three different PMMA+B₄C specimens. These tests were carried out with a Pin-on-Disc Tribometer, strictly according to ASTM A-99 criteria as the standard.The experimental setup prescribed specific parameters: an applied force of 5N, a sliding speed of 1m/s, and a sliding distance of 1200m. Within this controlled environment, the outcomes unveiled that the most substantial wear loss materialized in sample 1, exhibiting a value of 0.0000403g/s.
