olyester and vinyl ester resinbased linings are known for their solvent and chemical resistance. The different resins in these linings have broad resistance ranges, with acid resistance being a major strength. Some of the specific resins resist 1 or more chemicals or types of chemicals better than other resins, so systems often are finetuned by the choice of resin for a particular chemical envi...

This work presents an alternative to studying and determining the torsion modulus, G, in composites. For this purpose, we use a measuring system with rotation motion sensor coupled pendulum that allows for angular position as function of time. Then, through equation derived from mechanical spectroscopy studies permits calculation G’s value, experiments focus on samples different quantities calc...

Abstract Polymeric materials are used in different industrial applications because they retain good environmental properties, low-cost, and easy to produce compared conventional materials. This study investigated the effect of adding Kaolin particulate (KFP) Luffa cylindrica fiber (LCF) on mechanical properties polyester resin. was treated with 5% NaOH, varied weight fraction (5, 10, 15%wt), re...

In this study, thermal risk evaluation and reproduction experiments were conducted based on the case where fire was detected during epoxy-resin curing process, results provide technical data to prevent similar accidents . Epoxy resin (unsaturated polyester resin) is second petroleum product among Class 4 dangerous substances as determined through flash point, combustion ignition point tes ts. a...
