Abstract: Epoxy resin/ basalt fiber(EP/ BF) composites were fabricated via compression molding process using
BF cloth as the reinforcing agent and EP as the matrix. The effects of conditions as pressure applying moment, shaping
pressure and fiber volume content on the flexural properties and the interlaminar shear strength(LSS) of the composites
were investigated And the effects of incorporating attal ie/cabo(PG/C on the mechanical properties and thermal
conductivity of the composites were studied. Scanning electron microscope was used to observe the cross section
morphology of the composites. Results showed that the optimal pressure applying moment was 45 min the shaping
pressure and fiber volume content had effects on the flexural properties and ILSS of the composites. The incorporation of
PG/C-0.5(in which the mass ratio of cellulose to attapulgite was 0.5, the BF volume fraction was 30% and the forming
pressure was I Mpa) resulted in 4.3%, 10.7% and 6.4% increases in the flexural strength, modulus and ILSS of the
composites respectively with respect to those of the neat composites. The thermal conductivities of the composites were
0.28 W/(m K )and 0.31 w/(m K)at 25 C and 100 C with the increments of 64.7 and 41.0% respectively by
incorporating PG/C-0.5 compared with those of the neat composites. Such improvements of the mechanical properties
and the thermal conductivity attributed to the synergistic effect berween PG and the carbon coated on its surface.
