Strength of mechanically fastened joint in flat braided composite.

Finite Element - Based Strength Prediction for Notched and Mechanically Fastened Woven Fabric Composites

A literature review has been carried out relating to the damage and fracture behaviour of composite laminates based on woven fabric reinforcement containing a stress raiser in the form of either a circular hole or of a mechanically fastened joint – the tensile failure modes in these two types of problem are very similar. Closed form and finite element based approaches that enable the stress dis...

Recent Advances in Bolted composite Joint Strength Prediction

AMPTIAC Directory ... 15 The beginning In late 1993, the Mechanics and Surface Interactions Branch of the Air Force Research Laboratory’s Materials Directorate (AFRL/MLBM) was tasked to investigate the accuracy of the analysis methods used to predict the strength of bolted composite joints used on high-performance fighter aircraft such as the F-22 Raptor. The strength of bolted joints is essent...

Damage Development around Moulded-in Holes in Flat Braided Composites

Textile techniques like overbraiding offer the possibility to perform some function integration during the composite fabrication stage. As an example, it is possible to integrate axes or holes necessary to transfer loads to the composite structure. Moreover, this prevents drilling and therefore fracturing load-carrying fibres at a latter stage. However, this means a local reorientation of the f...
