powder coated towpreg was then wound around a frame stacked in a mold and consolidated under 300 psi one hour at 350 u00b0 c the composite specimen was slowly cooled to room temperature prior to removal from the mold test panels yielded panels with the strength properties plotted in fig5 and modulus properties as plotted in fig6 reaction sequence for the synthesis of a polymer metal oxide metal oxide encapsulated particle into a resin kettle equipped with a mechanical stirrer nitrogen inlet moisture trap and reflux condenser was placed 300 ml of o xylene the resin kettle was wrapped in glass wool and the solvent heated to reflux a 10 g sample of 10 weight percent solution of polymer in nmp was combined with 1 g of alkyl silicate teos and 9 g of zirconium butoxide and allowed to stir until homogeneous the resin mixture was added dropwise via an addition funnel into the refluxing o xylene the system was allowed to heat at approximately 140 u00b0 c with stirring overnight the solids collected and dried under vacuum 12 hours at 200 u00b0 c synthesis of a polymer metal oxide metal oxide encapsulated particle into a resin kettle equipped with a mechanical stirrer nitrogen inlet moisture trap and reflux condenser was placed 300 ml of o xylene the resin kettle was wrapped in glass wool and the solvent heated to reflux a 10 g sample of 10 weight percent solution of.
