Patent ID: 7118803

Claim:
A string-like composite structure sealing material (b), comprising a dimension-stabilizing aid other than a metal wire arranged along the lengthwise direction of a string-like body (a), wherein (1) the string-like body is obtained by forming a thermosetting resin composition comprising a synthetic resin and a heat-curing agent, (2) the elongation percentage thereof is within 10% as measured by applying a load to become stress of 5 N/cm 2 per unit sectional area at 23° C. for 5 minutes to the string-like composite structure sealing material in the lengthwise direction thereof, and (3) the string-like body (a) has shape-retaining ability at normal temperature (5 to 35° C.), but melt-flows upon its heat curing, wherein the string-like composite structure sealing material (b) is selected from the group consisting of a string-like composite structure (b1) which comprises the dimension-stabilizing aid composed of a linear material and a layer of the thermosetting resin composition formed around the dimension-stabilizing aid, and a string-like composite structure (b2) which comprises a string-like body formed by melt extrusion of the thermosetting resin composition and the dimension-stabilizing aid composed of a linear material embedded within the surface of the string-like body, and wherein the thermosetting resin composition further comprises a filler in a proportion of 0.1 to 50 parts by weight per 100 parts by weight of the synthetic resin.
