Investigation of the effect of surface modification types on the tribological performance of cow bone powder reinforced polymer materials

Abstract

This study investigated the production, characterization, mechanical and tribological performance of surface‐modified cow bone powder‐reinforced composites. The primary goal was to increase the tribological and mechanical performance of sustainable and cleanly produced composite materials. It was determined that the surface‐modified bone powder reinforcement increased the mechanical, thermal, and wear resistance of the polymer. The best surface modification method was determined as silanization. It reduced the friction coefficient and weight loss by 16.60% and 40.0%, respectively, according to the main factor analysis. In addition, it increased the glass transition temperature by 45.54%, crystallization by 2.93%, hardness by 2.70%, and tensile strength by 9.26% compared to the unmodified bone powder reinforcement.Highlights Surface‐modified cow bone powder‐reinforced composites were produced and characterized. The tribological and mechanical performance of the composites was investigated comprehensively. Surface‐modified composites improved the wear resistance. Surface‐modified composites improved the thermal resistance and mechanical properties. The best surface modification method was found to be silanization.

Mechanical and Rheological Evaluation of Polyester-Based Composites Containing Biochar

“…In particular, the composite containing 30 wt% biochar showed filler particles as dominant on the breakthrough/fracture surface. The results of the mechanical tests and the analysis of the breakthrough/fracture surface indicate that the filler surface is not sufficiently wetted by the matrix, indicating a lack of chemical interactions at the phase (filler-matrix) interface [32].…”

The results of the mechanical tests and the analysis of the breakthrough/fracture surface indicate that the filler surface is not sufficiently wetted by the matrix, indicating a lack of chemical interactions at the phase (filler-matrix) interface[32].The hydrophilic nature of most polymers limits the adhesion of natural fillers. This phenomenon is related to the presence of functional groups on the surface of the filler particles, mainly carboxyl and hydroxyl groups.…”
