Abstract
Polyoxymethylene (POM) needle-like crystals, whiskers, are known as trigonal crystals of very high perfection and are thought to have a high Young's modulus. In this study, composite films of the whisker were prepared as one possible method to utilize the whiskers as a new, high performance material. POM resin, i.e. a substance with the same chemical structure as the whisker, was selected as a matrix, having good adhesion with the filler (whisker). The whiskers were mixed with POM resin powder, prior to hot-pressing and made into the composite films, taking advantage of the difference of the melting points. The whisker content of the resulted film reached up to 70%. The Young's modulus of the composite film was increased up to about 14 GPa.
