Abstract
PURPOSE: To provide a type body which is light in weight, can be mass-produced, has a largely enhanced printing life and is used for typewriter or the like, by a method wherein a reinforced surface containing a high-hardness material is formed at the face part of a type body composed of a plastic (composite material).
CONSTITUTION: The entire of the type body 1 including a type part 2 is formed of a plastic or a composite material containing reinforcing fibers 7 dispersed uniformly, and the face part 6 is provided with a reinforced layer having highly abrasion-resistant fibers, a powder of high hardness or a mixture thereof incorporated in a matrix of plastic at a high density. The objective type body can be obtained, for example, by a method wherein a composite material prepared by incorporating a reinforcing fiber or a powder of high hardness into a thermoplastic at a high density of not less than 50wt% is dispersely filled into a type part cavity of a mold for the type body and then the material for the type body is injection-molded.
