“…Localized composite patches improve the intrusion properties of tubes without penalizing the overall part weight. 28 In Alnaser et al., 29 the crack propagation behavior of two repair types (full-encirclement and composite patch) used to repair through-wall defects on a pressure vessel was investigated. It was found that the two repair types have similar crack propagation behavior during fatigue testing.…”

In many industries, when replacement of a part is not possible or economic, the repair is done. One of the best methods for repairing metal and composite parts is using composite patches. Repairing with a composite patch is a widespread field to extend the service life of the cracked components. This technique is more structurally efficient with fewer damages on the structure than others. The bonded patch offers many advantages over a mechanically fastened doubler, which include improved fatigue behavior, reduced corrosion, and easy conformance to complex aerodynamic contours. In this article, advantages of the composite patch and its efficiency and durability are discussed, and the most important parameters (patch and adhesive thickness, patch separation, residual stress, patch length and width, etc.) affecting its performance are studied based on the latest available references.

“…Other studies have involved combining polymer composite materials with metal structures for reducing costs compared to using an entirely composite structure while maintaining excellent crushing performance from the contribution of both materials, such as the work by Kathiresan et al, 24 Alia et al, 25 Sun et al, 26 Zhu et al, 27 Lebaupin et al, 28 Huang et al, 29 Shiravand et al, 30 Zhang et al, 31 and Fortin et al 32 In certain studies, metal tubular structures are combined or wrapped with composite layers 24,25,27,[29][30][31] and in others, composite tubes have been filled with metallic foam structures 26 to achieve desirable crushing properties. Fortin et al tested hybrid columnar aluminum tube structures by inserting braided glass fiber composite rods inside aluminum tubes, resulting in improved specific energy absorption compared to the individual aluminum tube and braided rod components.…”

This article presents an experimental study on the quasi-static crushing performance of carbon fiber reinforced polymer (CFRP) rods consisting of unidirectional carbon fibers wrapped by braided glass fibers. Rods with and without a taper are tested and then inserted in extruded and expanded polystyrene foam and cardboard panels. Hybrid columnar aluminum tube–CFRP rod structures are also tested in all panel materials. These results are compared to those based on glass fiber reinforced polymer (GFRP) rods, GFRP rods in polystyrene foams, and to GFRP rods in cardboard from a previous study. Tapered CFRP rods exhibit progressive crushing behavior with specific energy absorption superior to GFRP rods, with values of 82 kJ/kg and 65 kJ/kg, respectively. Moreover, the highest specific energy absorption (111 kJ/kg) is obtained in hybrid columnar aluminum tube–CFRP tapered rods, exceeding values of aluminum tubes (89 kJ/kg) and equivalent structures containing GFRP rods (102 kJ/kg). Within panels, cardboard produces the largest increase in mean load of CFRP and GFRP rods due to most constraining fiber splaying during crushing, followed by extruded foam, and lastly expanded foam. However, crushing displacement is most restricted in cardboard due to earlier final compaction. The smallest variations in crushing load occur in extruded polystyrene due to greater homogeneity throughout the foam structure.
