PURPOSE:The titled sintered material, obtained by incorporating specific inorganic fibers and an organic peroxide with an ultrahigh-molecular weight polyethylene, and having a low linear expansion coefficient, high rigidity and good abrasion resistance without deformation by internal strain even under environment of high temperatures or great temperature changes. CONSTITUTION:A sintered material obtained by incorporating 100pts.wt. ultrahigh molecular weight polyethylene powder having >=1,000,000 average molecular weight measured by the viscosity method and >=3,000,000 average molecular weight measured by the light scattering method with 5-100pts.wt., preferably 30-80pts.wt. inorganic fibers having >=20 aspect ratio and 0.005-0.2pts.wt. organic peroxide, and sintering and molding the resultant mixture. |
