Title:

REINFORCEMENT MEMBER, METHOD OF MANUFACTURING REINFORCEMENT MEMBER, AND ENGINE BLOCK

Document Type and Number:

WIPO Patent Application WO/2005/009649

Kind Code:

A1

Abstract:

A reinforcement member, wherein a part of the reinforcement member is formed of a laminated structure (102) obtained by laminating a large number of steel plates (105) having openings (106) formed therein. A hollow portion (107) is formed in the laminated structure (102) to reduce the weight thereof. Also, porous bodies (103) formed of nonwoven fabric of metal fiber are disposed on the surfaces of the laminated structure in contact with matrixes to increase the adhesiveness thereof to the matrixes so as to prevent the separation of the reinforcement member from the matrixes. A cast product of light metal using the reinforcement member is small in thermal expansion though its weight is small and, for example, suitable for the journal part of an engine block.
