Abstract

The invention relates to the technical field of composite material preparation, in particular to a 3D printed grid ceramic reinforced resin composite material and a preparation method thereof. The 3Dprinted grid ceramic reinforced resin composite material is composed of three parts including grid ceramic, resin and an additive dispersed in the resin, and the grid ceramic is obtained by mixing aluminum ash and ceramic powder, carrying out molding through a 3D printer and carrying out drying and sintering, pores of the grid ceramic are filled with the resin and the additive contains a diluent and a curing agent. The preparation method of the 3D printed grid ceramic reinforced resin composite material has the following advantages: (1) the composite material is excellent in heat-conducting property, simple in preparation process and lower in cost, and (2) the pores of the grid ceramic reinforcement are easy to adjust, are continuous as a whole, the grid ceramic reinforcement is firmly combined with matrix resin, the strength is high, the toughness is good, the impact resistance is realized, and the use reliability and service life of the material are improved.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a 3D printing grid ceramic reinforced resin composite material and a preparation method thereof. Background technique [0002] Improving the wear resistance, heat resistance, thermal conductivity and thermal attenuation resistance of resin-based composites for friction materials is an important research direction for resin-based materials. The resin-based composite materials disclosed in the prior art are composite materials reinforced with fibers (two-dimensional) and particles (zero-dimensional). Such materials have the disadvantages of poor wear resistance, low heat resistance, low thermal conductivity, and weak resistance to thermal attenuation. This is because the microstructure of the two-dimensional or zero-dimensional reinforced composite material is that the reinforcing phase is embedded in the resin matrix material in a discontinuous form, and th...
