Abstract

This paper mainly studies the influence of nano/micro Al₂O₃ and Al(OH)₃ in epoxy composites on the ablation resistance, by quantifying the mass loss and observing the surface topography of sample after several times surface flashover in vacuum (the peak value is approximately 10kA, and the wave front is 8us, wave tail is 20us(8/20us)). The experimental results show that the addition of inorganic filler to epoxy resin is useful for improving the ablation resistance. The performance of Al(OH)₃ filler is much better than Al₂O₃. Nano-particles are much smaller and dispersed more uniformly than micro-particles. Thus the composite with nano aluminium hydroxide is of better heat dissipation. But the blocking effect of adding micro-particles is better than adding nano-particles.
