Abstract_FL A series of fuel gels are prepared from agarose gel (ag), ethanolamine fuel (C2H7NO) and energetic aluminum particles. The effect of the mass fraction of gel agent and aluminum particles on the volume combustion heat, centrifugal stability and rheological properties of the resulting gel fuel is tested by calorimetry, centrifugation and rheology. The microstructures of the particles and gels are characterized by scanning electron microscopy. The results show that when the mass fraction of aluminum particles is 30％, the volume combustion heat of the gel can be increased by 22.2％ with respect to that of pure gel; meanwhile, the centrifugal precipitation rate decreases from 26.5％ to 9.8％, and the stability of the gel is significantly enhanced. The results of electron microscopy and rheology show that the association of aluminum particles with the gel enhances the network structure, and increases the relaxation time and storage modulus.
