ABSTRACT:
A composite fastener member, in one form, having integral head and shank portions is defined by a plurality of superimposed composite fiber reinforced sheets spirally wound about a longitudinal axis. A plurality of fastener members, oppositely disposed within an opening in an article, define a fastener especially useful in joining lightweight composite structures such as aircraft or aircraft engine components. In another form, the ends of a single spirally wound composite fastener member are splayed to fasten a plurality of sheets.
