The increasing of effectiveness of the reinforce holes method for fasteners with composite liners

Abstract

The bearing capacity of a parts or units with a holes for fasteners and mechanical fasteners depends on the stress-strain state and its accompanying stress concentration in the local area of fasteners. In General, it is influenced by a set of operational and structural and technological factors. To replace the use of metal embedded elements, the technology of unloading the zone of point fastening of joints of composite structures is proposed by creating a combined connection with an intermediate element - a composite liner installed by a thermal compression method along the contour of the hole.
