The influence of different parameters in tribological characteristics of pineapple/sisal/TiO₂ filler incorporation

Abstract

In this experimentation hybrid composites using natural fibers and titanium oxide (TiO2) nano filler were fabricated using compression moulding technique. Pineapple (P) and Sisal (S) fibers were used as the natural reinforcements with epoxy as the matrix material. The mechanical results of flexural, impact and tensile properties found good improvement in the properties with SP fiber reinforcement (1:1 ratio) and TiO2 filler addition. The combination with 40 wt.% SP/5 wt.% TiO2 observed better mechanical results. The Taguchi optimization results showed lower Specific Wear Rate (SWR) by the incorporation of high TiO2 filler (5 wt.%) addition with the polymer-based composites. The filler substitutes replace the vacant space between fiber/matrix phase and add to the properties. The multi response optimization with TOPSIS proved that hybrid SP has the high influence in overall tribological properties of the natural fiber composites with rank 1 followed by filler incorporation. The results showed combination with 5 wt.% TiO2/20 wt.% SP Hybrid fiber/500 m Sliding distance/Sliding speed of 1 m/s and applied load of 5 N having optimized results.

Improve the interfacial properties of carbon fiber reinforced epoxy resin composites by maleimide‐modified waterborne polyurethane sizing agent

“…Polyurethane films are widely used in coatings, adhesives, biomedicine, the textile industry, and the paper industry due to their excellent elasticity and abrasion resistance 24–26 . Nowadays, epoxy resin as a matrix is widely used in carbon fibers, glass fibers, and various natural fibers 27–29 . Therefore, it is of great significance to improve the bonding performance between polyurethane sizing agent and epoxy matrix.…”

Effect of Synthesized Titanium Dioxide Nanofibers Weight Fraction on the Tribological Characteristics of Magnesium Nanocomposites Used in Biomedical Applications

“…Furthermore, it was proven that the incorporation of titanium oxide nanofiber into a metal matrix (aluminum) could improve the metal matrix mechanical properties [ 26 , 27 , 28 ]. In addition, many researchers used titanium oxide as a filler for enhancing the tribological properties of materials used in biomedical applications [ 29 , 30 , 31 ].…”

Dynamic Mechanical Analysis of Banyan/Ramie Fibers Reinforced with Nanoparticle Hybrid Polymer Composite

“…The filler substitutes fill in the gaps between the fiber and matrix phases, improving the characteristics. The use of TOPSIS for multiresponse optimization revealed that hybrid SP had the most impact on the overall tribological properties of natural fiber composites, with rank 1 being the most important, followed by filler incorporation [11]. Filler mixing improves fiber/matrix adhesion and increases mechanical characteristics.…”
