The composite technology is very important for production of high-functional or high-quality materials and products. We have studied the composite technology in processing of polymers and glasses. In this paper, I mainly present the research topics of mixing process of polymeric materials and multi-layered process of polymer films. For the mixing process of polymeric materials, we have developed the computer simulation techniques to predict the materials behavior in a twin-screw extruder and have proposed the methods to evaluate the mixing performance in melt mixing based on the simulation results. Such techniques and methods were applied to the melt mixing in engineering problems. For multilayered process of polymer films, we have developed the simulation techniques of multi-layered flow for viscoelastic fluids and discussed the unstable problem and encapsulation phenomena at interface from the case studies considering die configurations, rheological properties, etc. The neck-in phenomena of multi-layered film could be also understood from simulation results in a die. We also studied the method to evaluate viscoelasticity of interfacial layer for multilayered film using the parallel plate rheometer experimentally. We proposed the non-stick length of interface as an evaluation index. For processing of glasses using polymer-inorganic composites, we proposed processing method to give functions to glass products by using the formable polymer-inorganic composit as a precursor.
