Special Issue Information

Dear Colleagues,

High-Performance Resins have seen considerable growth in recent years due to the growing demand for lightweight materials in the automobile, aerospace and microelectronic industries, for example. High-Performance Resins can be used as structural materials and polymer electrolyte membrane fuel cells because they possess a combination of interesting properties, such as excellent mechanical strength per unit weight, high thermal stability and good insulating properties. In addition, their high thermal stability also qualifies them as excellent candidates for matrices in composites. Although general engineering plastics can meet the basic needs of modern industry, more crucial requirements, such as higher thermal resistance and excellent processability, should be put forward with the expansion of applications under harsh conditions.

This Special Issue invites original papers and reviews reporting on recent progress in the recent development of High-Performance Resins, with a particular focus on advances in the synthesis, characterization and application of High-Performance Resins in the high-tech industry. This issue welcomes focused review articles that examine the field, identify emerging trends, and suggest future directions for developing High-Performance Resins.

A scheme for manufacturing heavy-duty rail grinding wheels with silicone-modified phenolic resin (SMPR) as a binder in the field of rail grinding is presented to improve the performance of grinding wheels. To optimize the heat resistance and mechanical performance of rail grinding wheels, an SMPR for industrial production of rail grinding wheels was prepared in a two-step reaction using methyl-trimethoxy-silane (MTMS) as the organosilicon modifier by guiding the occurrence of the transesterification and addition polymerization reactions. The effect of MTMS concentration on the performance of silicone-modified phenolic resin for application in rail grinding wheels was investigated. The molecular structure, thermal stability, bending strength, and impact strength values of the SMPR were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and mechanical property testing, and the effect of MTMS content on the resin properties was investigated. The results indicated that MTMS successfully improved the performance of the phenolic resin. The thermogravimetric weight loss temperature of the SMPR modified by MTMS with 40% phenol mass at 30% weight loss is 66% higher than that of common phenolic resin (UMPR), exhibiting the best thermal stability; in addition, its bending strength and impact strength were enhanced by approximately 14% and 6%, respectively, compared with those of common UMPR. This study utilized an innovative Bronsted acid as a catalyst and simplified several intermediate reactions in the conventional silicone-modified phenolic resin technology. This new investigation of the synthesis process decreases the manufacturing cost of the SMPR, liberates it from the restrictions of grinding applications, and enables the SMPR to maximize its performance in the rail grinding industry. This study serves as a reference for future work on resin binders for grinding wheels and the development of rail grinding wheel manufacturing technology. Full article
