摘要: Abstract Temperature dependence of the fracture toughness epoxy composites reinforced with nano- and micro-silica particles was evaluated. Epoxy containing varied composition ratios ΦSP spherical particles, 240 nm 1.56 μm, were prepared at a fixed volume fraction (VP = 0.30). The thermo-viscoelasticity neat measured 143 K, 185 K, 228 K, 296 K, 363 K, 399 K. Experimental results revealed that strongly depended on microstructure micro-particles bidispersion as well its interactions matrix all temperature, but toughened due to increase in mobility relaxation temperatures.
