ABSTRACT:
An improved carbon fiber tape of an open weave construction is provided. The tape comprises a plurality of adjacent substantially parallel and spaced linear warp ends of a carbonaceous fibrous material containing at least 90 percent carbon by weight substantially coextensive with the length of the tape in absence of substantial lateral contact between adjacent warp ends, and a weft pick containing at least 90 percent carbon by weight interlaced with the warp ends in a plain weave construction at a frequency of about 2 to 8 picks per inch of tape with the weft pick being provided under a tension sufficient that the linear configuration of the warp ends is substantially unimpaired. The carbon fiber tape of the present invention may be utilized in the formation of pervious low density composite articles when impregnated with a thermosetting resinous matrix.
