Abstract

PURPOSE: To prepare a gasket exhibiting low creep and stress relaxation, and having excellent sealability and memory effect, by dispersing specific short fibers having high elasticity and strength uniformly in a rubber matrix at a specific ratio, and forming and vulcanizing the matrix to a sheet thereby integrating the matrix with the fiber.
CONSTITUTION: For example, short fibers 3 of 1W50μ in diameter and 0.5W10mm in length and made of Kevlar fiber having high elasticity and strength, are added to a matrix 2 made of a rubber (including other resin elastomer) at a weight ratio of 5W50%, and dispersed uniformly by kneading, etc. The mixture is formed to a sheet and vulcanized to obtain the objective gasket wherein the short fibers 3 are integrally bonded to the matrix 2. Since the sheet has planar anisotropy caused by the orientation of the fiber by the kneading roll, it is preferable to laminate two or more layers.
