THERMOSETTING RESIN COMPOSITION

摘要

PURPOSE:To provide the titled compsn. which gives moldings having excellent mechanical strength and high electrical conductivity (10<-3>-10<0>OMEGA.cm), by mixing graphite and carbon fiber with a thermosetting resin in a specified ratio. CONSTITUTION:40-80wt% graphite (A), 4-25wt% carbon fiber (B) having a fiber length of 0.1-6mm. and a resistivity of 1X10<-3>-20X10<-3>OMEGA.cm and the balance of a thermosetting resin (C) (e.g. a phenolic or opoxy resin) are mixed together in such a proportion that the combined quantity of components A and B accounts for 60-85wt% of the total quantity of the compsn. The mixture is crushed in a ball mill into a powder having a particle size of 100mu or below.
