Development and Elastomeric Processing of Woven Graphite/Epoxy Structural 'T' Sections.

Abstract

This program applied woven and unidirectional graphite/epoxy prepreg to the fabrication of spar-to-wing-cover joint concepts that are integrally cured. The program screened and developed the root area filler for these elements, such that crack formation, growth, and ultimate failure would not occur in this critical region. Results indicated that a rolled, layered composite root filler using glass scrim cloth and a staged commercial film adhesive with carrier provided adequate strength in the root area. A reticulated foam filled elastomeric tool was demonstrated to be both practical and of low cost in fabricating quality structural specimens. This tool technique is considered to be both practical and cost effective in a production situation. (Author)
