Outline of Final Research Achievements

This study establishes basic technology for making plastics kneaded with fillers made of various materials by injection molding machine and examines how the sample kneaded with filler changes with us. First, a plurality of kinds of metal powder, ceramic powder, Japanese paper fiber were kneaded in polypropylene as a base material, and then an egg type sample was prepared by a manual injection molding machine. As a result, it was found that molding was possible relatively easily except for those kneaded with the paper. Finally, by comparing the sample immediately after molding with the sample polished by a shaker according to the subject experiment, the relation between filler and texture change was clarified.
