SiC was partially infiltrated into three types of carbonized paper-fibre preforms using pressure-pulsed chemical vapour infiltration from SiCl(4)(4%)-CH(4)(4%)-H(2) at 1100 degrees C (A-type preforms, source fibres of filter paper; B(H)- and B(L)-type preforms, source fibres of recycled paper). The porosity of the preforms decreased linearly with the number of pulses. After 10 000 pulses, the porosity of A-, B(H)- and B(L)-type samples was 77, 78 and 85%, respectively. Average pore sizes of A-, B(H)- and B(L)-type samples after 10 000 pulses were about 5.0, 2.7 and 7.0 mu m, respectively. On an A-type sample of 10 mm phi and 5 mm long after 10 000 pulses, pressure drop along the direction of axial air flow was 10 kPa at a face velocity of 0.8 m s(-1). The order of pressure drop was B(H) > A >B(L). Flexural strength of A-type sample reached 10 MPa after 15 000 pulses. (C) 1998 Kluwer Academic Publishers.
