Paper Title:
Mechanical Properties and Micromorphologies of Methyl- Silsesquioxane/Cyanate Ester Resin Organic-Inorganic Hybrids
  Abstract

A kind of nonfunctional oligomeric silsesquioxane (SSQ), methylsilsesquioxane (Me-SSQ), was used to modify cyanate ester resin (CE) in this paper. First, Me-SSQ was synthesized by the hydrolysis and condensation of methyltriethoxysilane. Then a series of Me-SSQ/CE hybrids containing 0wt%, 1wt%, 5wt%, 10wt% and 20wt% of Me-SSQ were prepared. Curing reactivity of the hybrid materials was studied by differential scanning calorimetry (DSC). Mechanical properties of the Me-SSQ/CE hybrids were studied systematically. Impact strength of the Me-SSQ/CE hybrids reaches its maximum value when Me-SSQ content is 5wt%. However, the flexural strength reaches the maximum value when Me-SSQ content is 1wt%. SEM images accord well with the mechanical properties. It is concluded that appropriate amount of Me-SSQ is favorable to improve the mechanical properties of Me-SSQ/CE hybrid materials.
