INTRODUCTIONMachine tool bed plays an important role in the manufacturing industry, which could provide mechanical products of better precision and surface quality. However, vibration generated in the machining process has much more influence on the dimensional precision and surface quality of the workpiece, which prohibits high-speed and high-precision machining from developing rapidly. How to minimize vibration during the manufacturing process is now an important factor that affects machining precision and the stability of machine tool [1] [2].Resin mineral composite (RMC) is a composite material similar to plain concrete that it is composed of granite particles as solid aggregate. The difference is that the binder is organic resin. With the development of high-speed and high-precision machining technology, RMC has attracted more and more attention for its good vibration alleviating properties [3]. Compared with gray cast iron and welded steel, RMC has ten times the damping ratio that it can better absorb vibrations generated in the machining process, especially in high-speed and high-precision machining processes [2] [4]. However, the application of RMC is restricted by its limitation in mechanical strength, and considerable research should be done to improve its mechanical properties in order to satisfy the requirements of high-speed and high-precision machining.The mechanical strength of fully cured RMC is highly related to its components and the interface between the resin matrix and filler [5] on the mechanical strength of RMC. However, little information has been focused on the influences of aggregate moisture content on the mechanical strength of RMC. As the key component in RMC to bear loads, the aggregate weight of the total composite material accounts for more than 85%, the physical and chemical properties of the aggregate has a significant impact on the mechanical properties of RMC [5]. Influence of aggregate moisture content on the mechanical strength of RMC was not received sufficient attention. Fontana and Reams [14] revealed that 3% of pre-existing water in aggregates reduces the compressive strength of the PC by half. Header and Mohammad [15] found that the polymer concrete's flexural strength decreased from 25.8 MPato 0.68 MPa and compressive strength from 190MPa to 85 MPa when the initial moisture added to the aggregate content increased from 0% to 5%. However, data is still scarce. We need to provide more documents. In this International Conference on Chemical, Material and Food Engineering (CMFE-2015)

With excellent vibration alleviating properties, resin mineral composite (RMC) has attracted special attention in the field of mechanical engineering. However, applications of RMC are restricted because of its limited mechanical strength. In this research, the glass fiber (GF) was added into RMC to increase its mechanical strength, and the effect of the length and mass fraction of GF on the mechanical strength of GF/RMC were investigated. Results showed that the compressive strength and flexural strength of RMC first increased and then decreased as the length and mass fraction of GF increased. In order to improve the interfacial bonding between GF and RMC, the GF was subsequently treated by ultrasonication, oxidation, and silanization.

Resin mineral composite (RMC) consists of epoxy resin, granite aggregate and fly ash, and which can be used to produce precision machine tool beds due to its superior vibration alleviating properties. However, applications of RMC are restricted due to its limited mechanical strength. In this paper, the effects of the air void on the compressive strength of RMC were firstly introduced. Then the effects of vibration time, initial temperature of resin, mass of compression mould, vacuum degree, number of layers and mass content of defoamer on the air void and compressive strength of RMC were thoroughly investigated. Experimental results show that the air void (compressive strength) of RMC first decreases (increases) and then stabilizes as the vibration time and number of layers increases. Results also show that the air void (compressive strength) of RMC first decreases (increases) and then increases (decreases) as the initial temperature of resin, mass of compression mould, vacuum degree and mass content of defoamer increases. In order to further reduce the air void of RMC and increase the compressive strength of RMC, five different compound technologies (i.e., CTA, CTB, CTC, CTD, CTE) at different temperature (10°C and 40°C) were investigated. The optimum air void (compressive strength) of RMC was achieved by the CTE at 10°C, in which the air void (compressive strength) decreased (increased) by 44.4% (19.7%) compared to the RMC poured by CTA (standard pouring technologies) at 10°C. Afterwards, the relationship between air void and compressive strength of RMC was studied systematically. POLYM. COMPOS., 39:457–466, 2018. © 2016 Society of Plastics Engineers
