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.

As part of the endeavor to establish new optical manufacturing technologies, to include the manufacture of aspheric optical surfaces using traditional and non-traditional methods, a reference study that explains the concept of aspheric optical surfac
es and their design considerations relative to spherical ones has been conducted. A study of international manufacturing methods and in our controlled manufacturing methods using the technologies and equipment available to us as well has been done. These studies provide the possibility and expertise to manufacture new types of optical surfaces. The results of these studies are applied on the technologies available to us for use in the manufacture and measurement of aspherical optical surfaces.
