REINFORCEMENT MEMBER, METHOD OF MANUFACTURING REINFORCEMENT MEMBER, AND ENGINE BLOCK |
摘要 |
A portion of a reinforcing member has a stacked structure 102 in which plural iron plates having openings 106 are stacked. A hollow portion 107 is formed inside the stacked structure 102, so that the reinforcing member is reduced in weight. Porous bodies 103 composed of non-woven fabric of metal fibers are disposed on surfaces contacting matrixes, so that adhesion between the reinforcing member and the matrix is improved, and peeling therebetween is prevented. A cast product which is composed of light metal and has the above reinforcing member has a small thermal expansion. For example, the cast product is desirable for use for a journal portion of an engine block. |
