“…However, applications of cement concrete in the machine tool bed are constrained due to its defects such as larger brittleness, poor acid resistance, poor waterproofness, poor impact toughness, and high drying shrinkage . Similarly, applications of cured epoxy resin and fiber reinforced cured epoxy resin in the machine tool bed are restricted due to its inferior properties such as lower compressive strength, high cost, high thermal expansion, and high curing shrinkage.…”

For excellent damping properties, polymer composite (PC) has drawn particular attention in the field of modern ultra‐precision machining (UPM). However, applications of PC are restricted due to its inferior mechanical strength. In this paper, different granite coarse aggregate, different fine aggregate, and different filler were added into PC to increase its mechanical strength. The effects of coarse aggregate type, fine aggregate type, filler type on the mechanical strength of particle‐filled polymer composite (PFPC) were investigated systematically. Experimental results show that the best mechanical strength was obtained when the coarse aggregate type is Jinan clay granite, the fine aggregate is Jinan clay granite, and the filler is fly ash (FA). Results also show that the compressive strength of PFPC was closely correlated with the compressive strength of aggregate rock, and the compressive strength of PFPC increases with the increasing compressive strength of the aggregate rock. In order to further improve the mechanical strength of PFPC, the aggregate was subsequently treated by ultrasonication, direct mixing silanization, nebulizing silanization, macerating silanization. And four types of PFPC were obtained, that is, U‐PFPC, D‐PFPC, N‐PFPC, M‐PFPC, respectively. Among these four types of PFPC, the M‐PFPC exhibited the best mechanical strength. And the compressive strength and flexural strength of M‐PFPC are 146.97 MPa and 37.33 MPa, respectively; increased by 8.31% and 13.53% compared with PFPC produced by standard pouring technologies. In addition, the mechanism of the influence of the aggregate whose surfaces were treated on the mechanical strength of PFPC was revealed by scanning electron microscopy and contact angle test. The test results show that the M‐PFPC exhibited the favorable interface bond. This study was of great significance to increase the mechanical properties of PC and improve its application in precision machine tools.

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.
