Several mechanical properties and morphology of tetrafunctional epox resins (Tetrad^[○!R] D and X cured with hexahydrophtharic anhydride (HHPA), abbreviated as EP・D and EP・X) filled with graphite fluoride powders (GF) such as (C_2F)_n (C2F) and (CF)_n (C1F) were studied using a Rheovibron, an lnstron tester, a Vickers hardness tester, and a SEM. C2F and C1F were added to EP・D and EP・X up to 30 wt%. C2F treated with six coupling agents (CA) was added to EP・D by 30 wt%. The GFs were distributed randomly in all the specimens. The glass transition temperature (T_g) and the storage modulus (E') of all the GF-filled specimens became larger with increasing content of GFs. The filling effect of GFs on the E' of the EP・D and EP・X filled with GFs was smaller than of difunctional epoxy resin (Epikote^[○!R] 828 cured with HHPA). The compressive strength values (σ_c) of the C1F-filled specimens were larger than those of the C2F-filled specimens. The Vickers hardness values (Hv) of the GF-filled EP・D increased and those of the GF-filled EP・X decreased remarkably with increasing content of GFs. The effects of coupling treatment of CAs for C2F on E', σ_c and Hv of the filled specimens were different depending upon the kind of CA.
