A novel processing technique for fabricating the integrated composite particles has successfully developed by present research group. It was useful for developing the novel functional nano-composite, due to control the microstructure in composite. However, small amount of integrated composite particles was obtained by proposed conventional processing method, meaning that it is difficult to use practical applications for fabricating functional composite materials. In order to fabricate large amount of integrated composite powder, further improvement of fabrication technique needs for innovation of materials science. The manufacturing system with high productive capacity of composite particles has developed on basis of colloidal science in this project and then, useful examples of application for fabricating the composite powders were proposed to popularize as key technology in the material industry. The productive capacity of composite particles was enhanced up to 5kg/h by use of the proposed controlling technique in this period. Novel design of mixing device to obtain heterogeneous composite particle was developed in this study. Proposed device has special geometry comprising with holes and tapered tube which are connected in series. This geometry is sufficient enough to mix two kinds of particles, yielding the homogenous composite particle with continuously. The surface charge control device has also improved to achieve the high productive capacity of composite particles. Thus, the desktop fabrication system for fabricating the composite has successfully developed in this period. In addition, novel powder granulation process also proposed by use of surface charge-controlled particles prepared by developed device. The composite particle, i.e., composite granule in this case, with wide range of composition ranging from 0 to 100% was utilized as raw powder for fabrication the functionally graded materials. Useful applications for composite particle were also scrutinized in this research period. The novel designed composite particle was proposed for the additive manufacturing processing. The developed SiC-Al2O3 composite particle was exhibited the sinter and melt behavior for irradiation of a near infrared wavelength region laser. It is implying that the direct laser 3D printing is possible by use of composite particle developed in this study.
