Friction and wear behavior of glass fabric/phenolic resin composites with surface‐modified glass fabric

Abstract

Untreated, air-plasma-bombarded, and b-aminoethyltrimethoxylsilane-silanized glass fabric (GF) was used to prepare GF/phenolic composites by dip coating in a phenolic adhesive resin and successive curing. The tribo-performances of these GF/phenolic composites sliding against AISI-1045 steel were evaluated with a pin-on-disc wear tester. The chemical composition of the untreated and surface-treated GF was analyzed with Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The interfacial regions between the phenolic resin and GF and the worn surfaces of the composites were analyzed with scanning electron microscopy. The results show that the GF/phenolic composite with b-aminoethyltrimethoxylsilane-silanized GF had the highest load-carrying capacity and best tribo-performance, and it was followed by the composite with plasma-treated GF. The improved tribo-performance of the GF/phenolic composite made of surface-treated GF was attributed to the strengthened interfacial bonding between the treated GF and the phenolic adhesive resin.

Silver‐Doped Zinc Oxide as a Nanofiller for Development of Poly(vinyl alcohol)/Poly(vinyl pyrrolidone) Blend Nanocomposites

“…Hence, this technique has been extensively used in plastics, rubbers, composites, and adhesives. [1][2][3] The properties of the blend depend on the degree of compatibility or miscibility of the polymers at molecular mixing; blends can be classified as a compatible blend or completely miscible and incompatible or immiscible blends. [4][5][6] The polymer miscibility is due to some specific interactions such as dipole-dipole forces, hydrogen bonding, and charge transfer complex between the polymer segments.…”

The Preparation and Wear Behaviors of Phenol–Formaldehyde Resin/BN Composite Coatings

“…Many papers have reported that phenolic-matrix composites exhibit excellent synergistic effects on mechanical and tribological properties. Different reinforcements, such as glass fibers/fabric, carbon fibers [ 6 ], ceramic nanoparticles, graphene, and soft metals, have been used to promote tribological properties [ 7 , 8 ]. Suitable interfacial bonding, such as surface modification, including acid etching, plasma bombardment, and chemical grafting, is needed to improve the tribological properties of phenolic composites [ 6 , 7 , 8 ].…”

“…However, the aggregation of BN increases the roughness, and the particles can be easily pulled out [ 9 ]. Combining physical interactions with chemical interactions between reinforcements and resin can improve the tribological behavior of polymer composites [ 8 ]. Many methods, such as the introduction of an interfacial linker and plasma treatment, provide strong interlock forces and chemical interactions in the interphase [ 6 , 11 ].…”

Effects of solid lubricants on the tribological behavior of steel‐backed UHMWPE fabric composites

“…30 Combining fillers with UHMWPE fabric requires a basic matrix, which is commonly resin, such as epoxy 31 and phenolic resins. 32 However, due to the low-surface energy of UHMWPE fiber and lack of polar functional groups, its surface is smooth and inert, such adhesion between fabric and matrix is not ideal. 33 Due to low-interfacial bonding forces, composites need to be modified before sizing and bonding.…”
