C/ C-PAA and C/ C-FA composites were prepared by PIP process,X-ray diffraction of PAA and FA
resin carbon,impregnation result of PAA and FA resin,flexural strength of C/ C-PAA and C/ C-FA were studied. It is
show that PAA resin carbon has better initial structure and impregnation result than FA resin carbon;flexural strength
of C/ C-PAA is 34. 9% higher than that of C/ C-FA,flexuural modulus contrast is not obvious.
