CONSTITUTION:Silicon carbide fiber, silicon carbide particles and glass fiber are respectively mixed, for example, preferably at a ratio of 10-50% (by weight), 20-60% and 20-50% with plastic such as phenol resin or the like in such a manner that the total amount of the above three contents becomes totally less than 70%. The objective type unit is obtained with the plastic composite material.
