Mineral composite material (mineral casting) is a new type of composite material formed by modified epoxy resin and other materials as binders, granite and other mineral particles as aggregates, and reinforced by reinforcing fibers and nanoparticles. Its products are often called minerals. casting. Mineral composite materials have become a substitute for traditional metals and natural stones due to their excellent shock absorption, high dimensional accuracy and shape integrity, low thermal conductivity and moisture absorption, excellent corrosion resistance and anti-magnetic properties. Ideal material for precision machine bed.
We adopted the medium-scale modeling method of high-density particle-reinforced composite materials, based on the principles of material genetic engineering and high-throughput calculations, established the relationship between material component-structure-performance-part performance, and optimized the material microstructure. Developed mineral composite materials with high strength, high modulus, low thermal conductivity and low thermal expansion. On this basis, the machine bed structure with high damping properties and the precision forming method of its large-scale precision machine bed were further invented.
1. Mechanical Properties
2. Thermal stability, changing trend of temperature
In the same environment, after 96 hours of measurement, comparing the temperature curves of the twomaterials, the stability of mineral casting (granite composite) is much better than grey casting.
3. Application areas:
Project products can be used in the manufacture of high-end CNC machine tools, coordinate measuring machines, PCB drilling rigs, developing equipment, balancing machines, CT machines, blood analysis equipment and other fuselage components. Compared with traditional metal materials (such as cast steel and cast iron), it has obvious advantages in terms of vibration damping, machining accuracy and speed.
