Title:
PREFORM FOR COMPOSITE MATERIAL AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/091471
Kind Code:
A1
Abstract:
A preform for composite materials which has high strength and excellent air permeability
and is hence applicable to the high-speed die-casting method and from which a
metallic composite material capable of having excellent mechanical properties
can be formed by the high-speed die-casting method. Ceramic fibers (2) or/and
ceramic particles (3, 5) are mixed with a silica sol (7) and calcium carbonate
(4). The mixture is sintered at a given temperature. Thus, a preform (1) for composite
materials is obtained which comprises: a calcium/silicon sinter (11) yielded
from the silica sol (7) and calcium carbonate (4); and the ceramic fibers (2) or/and
ceramic particles (3, 5) coated with the calcium/silicon sinter (11), the fibers
(2) or/and particles (3, 5) being bonded to each other with the sinter (11). The
preform (1) for composite materials has high strength and excellent air permeability
and is applicable to the high-speed die-casting method capable of attaining
high productivity.
