| Outline of Final Research Achievements |
Mechanical properties of epoxy composites filled with nano-silica particles with different crosslinking densities were experimentally studied to clarify the interaction effects between nano-particles and the network structure in matrix resins on the properties. The composites were cured non-stoichiometrically to manufacture specimens having different network structures. The elastic moduli of the composites were dependent on only the volume fraction of the particles. Filling the nano-silica particles was clarified to improve the bending strength and fracture toughness of the composites with a fine network structure. However the particles acted as defects, reducing the mechanical properties of the composites with rough network structures.
