The Properties of Hybrid Fiber Reinforced Metal and It's Application for Engine Block 890557
The weight-saving requirements for automobiles are important. In order to produce a lighter engine, an aluminum block with cast-iron liners and a hypereutectic aluminum-silicon alloy block have been developed. (1)*, (2), (3), (4), (5), (6)
We developed a new aluminum engine block which has the cylinder bore surface structure reinforced with short ceramic fiber.
We also established technology suitable for mass-production including a fiber preform process and a non-destructive inspection method.
In this paper, the optimum properties and production technology of MMC engine blocks are introduced. A portion of the paper is dedicated to the results of a comparison study between a new light-weight aluminum engine block, a hypereutectic aluminum-silicon engine block and an aluminum engine block with cast-iron liners.
