Abstract
Composites of poly allyldiglycolcarbonate (ADC) and nano-sized silica particles were investigated in search of an alternative method to improve the fracture toughness of ADC resin. Transmission electron microscope studies revealed relatively uniform dispersion of silica particles in the resin. Dynamic mechanical analysis measurements indicated that an increase in the glass transition temperature of ADC resin was also accompanied by a higher flexure modulus. A small but significant increase in the fracture toughness of the composites was also observed. The fracture surfaces studied by scanning electron microscopy did not reveal silica particles even at very high magnification and appeared to be featureless smooth surfaces.
