Development of ceramics resin concrete with some excellent properties

一种被称为陶瓷树脂混凝土的新材料已经被开发出来用于某些结构。这种材料由环氧树脂和陶瓷组成，即氧化铝、碳化硅、氧化锆或它们的混合物。对复合材料的一些性能进行了实验和理论研究。此外，还尝试了一些工业材料的应用。所得结果如下：(1)建立了一种实用的陶瓷树脂混凝土制造方法。(2)杨氏模量为60%，密度为95%，导热系数为50%，线膨胀系数为1.2倍，比热系数为1.2倍，对数衰减量为60倍，断裂韧性为1.6倍。(3)所开发的程序可以从组成材料的物理性质和体积波动中估计出一些基本的热性能和力学性能。(4)陶瓷树脂混凝土的断裂韧性远远优于普通陶瓷，这是由于裂缝挠曲或微裂缝增加了裂缝的抗扩展能力。(5)用简单的方法和设备制造了大型结构，工作时间短，成本低。(6)使用这种材料的数控车床刀架的刀具寿命是传统数控车床的5倍。

A new material referred to as ceramics resin concrete has been developed for use in some structures. This material consists of epoxy resin and ceramics, i.e., alumina, silicon carbide, zirconia, or a mixture of these. Some properties of the compound material were experimentally and theoretically investigated. In addition, a few application for industrial material have attempted. The results obtained are as follows.(1) A practical manufacturing method for the ceramics resin concrete was established.(2) Young's modulus was 60%, density was 95%, thermal conductivity was 50%, coefficient of linear expansion was 1.2 times, specific hear was 1.2 times, logarithmic decrement was 60 times and fracture toughness was 1.6 times, that of the used aggregate.(3) The developed program can be used to estimate some of the fundamental thermal and mechanical properties from the physical properties and volume fluctuation of the constituent materials.(4) Fracture toughness of the ceramics resin concrete was far better than ordinary ceramics, because of the crack extension resistance is increased by the crack deflection or microcracking.(5) A large sized structure has been made with simple method and equipment, short working time and low cost.(6) Tool life in a NC lathe with tool post using this material was five times that of conventional NC lathe.
