Jointing of high-loaded composite structural components. Part 1. Design and engineering solutions and performance assessment

The author presents and discusses the results of investigation to verify the design principles for jointing composite components. Based on the findings, novel design and engineering solutions for metal-composite joints are put forward. To ensure an effective transition from a composite material to a metal butt-joint fitting, new jointing techniques have been developed involving the use of embedded longitudinal and transverse fastening microelements in a composite material, which are molded into or mounted on a metal component. A modification of half-stitch jointing is proposed which enables the joint to work in compression and reduces the pressing stresses in the winding zone. Based on the study of force transfer conditions in the proposed joint design and the jointing solutions, the author defines the main lines of theoretical and experimental investigations to support the engineering and stress analysis activities. The experimental static strength assessment demonstrates effectiveness of the proposed solutions. __________ Translated from Problemy Prochnosti, No. 3, pp. 23–33, May–June, 2006.
