The Material Design And Properties Of Resin Concrete Material Based On The Thermal Stability

Precision and ultra-precision processing, as the symbol of manufacturingtechnology level of a nation, have become one of the important means in thecompetition of science and technology, even armament, which requires the support ofadvanced processing equipments with high precision, dynamic stability and thermalstability. However, traditional iron material fails to satisfy these requirements anymore. Therefore, a kind of material with good mechanical performance and excellentthermal stability was desperately needed.Due to the good mechanical performance, excellent thermal stability and perfectvibration resistance, resin concrete was very approperite to act as precision machinebed. Many aspects of resin concrete material were investigated in this paper.Firstly, aggregates, fillers and resin binder materials, which consisted of resinconcrete, were completely studied, compared and chose. Secondly, the aggregatesgradation of resin concrete was fully discussed and a novel math optimal model ofaggregates particles packing was established on the base of Dinger-Funk Formulawith particle size distribution of each grade introduced to aggregates gradation. Thegradation solution of it also was more accurate. Thirdly, resin concrete were preparedand tested according to the results of aggregates gradation. The processing technologyof resin concrete preparation was also further studied. Finally,2D and3D aggregatesparticle packing model was set up by Matlab software and the properties of thepacking model were simulated by Ansys finite-element analysis software.The math optimal model of aggregates gradation filled the blank of aggregatesgradation theory of resin concrete used for precision machine bed. The specimenpreparation and properties test also left a reference for further study. What’s more, theaggregates particle packing model had a more intensive density and the analysis resultwas more accurate.
