Joining And Repair Of Composite Structures (Astm Special Technical Publication, 1455.) (Astm Special Technical Publication, 1455.)

Twelve peer-reviewed papers provide the latest information on the design, analysis, testing, and fabrication of structural joint and attachment configurations. Topics cover: Adhesively Bonded Attachments includes two useful analysis techniques on closed-form model development and the development of a test specimen configuration suitable for the strength measurement of lap joints loaded under in plane shear. This section also investigates a new double-strap joint design configuration that makes use of extra attachments to improve significantly the joint strength; the correlation between analysis and testing of thick section thermoplastics composite-to-titanium for a marine application; and a "bondable" peel ply application for bonding fiberglass skins to a polyamide honeycomb core. Adhesively Bonded Repair addresses the repair of new armor concepts that are to be used on advanced composite military vehicles, with particular focus on characterizing the dynamic response of the adhesive joints formed in scarf repairs; and the repair of thick steel structures used in earth excavation equipment. Bolted Attachments discusses mechanically-fastened joints, as well as cover bolted and riveted composite joint analyses; the Strain Invariant Failure Theory (SIFT&341; bolted joint failure prediction; and the use of nonlinear finite element analyses for predicting failure in composite joints based on lamina-level failure criteria.

Sawicki The 12 papers in this collection from the March 2003 symposium address the design, analysis, and testing issues associated with the adhesive bonding of composites, adhesively bonded repair, and mechanically fastened joints. The opening papers apply the sublaminate method to the analysis of bonded joints and propose a theoretical model which can estimate the failure limit of in-plane shear loaded adhesively bonded joints. Other topics include the evaluation of a carbon thermoplastic to titanium bonded joint, the installation of adhesively bonded composites to repair carbon steel structure, and a composite bolted joint static strength prediction tool.
