Fibre-reinforced composite material and method of producing the material

摘要

A fibre-reinforced composite body (1/2/3) e.g. a connecting rod comprises a shaped article (F) of fibres of precipitation hardenable stainless steel which has been subjected to a solution heat treatment, and an aluminium alloy matrix (M) filled around, into and integrated with the fibre shaped article (F) by high pressure solidification casting. The body is then heat treated for the fibres to be precipitation hardened and the matrix to be solution heat treated. Finally the body is reheated and cooled to provide an artificial ageing for the aluminium alloy.
