Static Strength of Mechanically Fastened Carbon-Epoxy Joints Without Bending

摘要

The mechanical behavior of mechanically fastened double lap carbon-epoxy joints has been investigated both by experiments (static tests) and by analysis. Several fastener types and joint geometries has been investigated. In the experimental program the Fibredux 6376/T400H material was used. Two methods to analyze mechanically fastened composite joints are described: a semi-analytical method in which Nuismer's point failure criterion is applied to an analytically determined stress distribution and a finite element based computer program BOLT. A good agreement between test and analysis was found.
