In this work composite hybrid materials were prepared from a base
material composed of epoxy and phenol - form aldehyde resins and
reinforced by 30% wt alumina and silica powders and asbestos
fibers. For samples were prepared with. Different ratio of
reinforcing material.
Modified resole resin/short silica fiber composite materials have been prepared.
The resole resin was synthesized and then blended with Polyvinylbutyral (PVB)
polymer with different weight ratios to reduce its brittleness. The mechanical,
thermal
and physical properties of Resol- PVB blends were studied to
characterize these blends and select the most appropriate mixing ratio of
polyvinyl butyral with resole resin, which was identified at 15 phr of polyvinyl
butyral for every 100 parts of resole resin.
