The optimum performance of the pipe was achieved when the ± 45° winding angle was set, but the layer number and diameter-to-thickness ratio met the relevant standards.

The single-lap bonded joints specimens were made of [0]<sub>8</sub> layered woven glass fiber/epoxy composite plates joined together by adhesive. Two different thermal aging processes were applied to adhesive- bonded single-lap joints specimens. In the first process, temperatures of 75, 100, and 150°C were applied during the aging time of 4 h. In the second process, a constant temperature of 150°C was applied for aging times of 2, 4, and 8 h. Additionally, this study was carried out in a temperature-controlled oven, without considering humidity, using three different adhesive thicknesses (0.2, 0.4, and 0.6 mm) and three different overlap lengths (15, 30, and 45 mm). After the thermal aging process, the specimens were subjected to a tensile test to determine the failure loads. Furthermore, the hardness values of both the adhesive and the composite plate were investigated under the conditions of 4 h at 150°C. The failure loads and microstructural changes determined were compared with the results for control specimens kept at room temperature (25°C). It was found that the increase in hardness values positively affected the strength of both the adhesive and the composite. With increasing the thermal aging time, temperature, and overlap length, the failure loads increased by 8.4 to 79.1%, 14.4 to 79.1%, and 9.5 to 50.9%, respectively.

The microscopic morphology of the joint at each stage of the failure process was obtained by tensile-shear test and electron microscopy scan, on which the changes of CFRP, aluminum plate, rivet, and adhesive layer at different stages were further discussed to reveal the failure mechanism of the joint. The results showed that the joint strength could be improved by appropriately increasing the riveting pressure. The surface treatment of aluminum plate could improve the surface properties of the joint, and the joint strength showed a trend of first increasing and then decreasing with the increase of the sandpaper mesh. Increasing the lap length led to an increase in joint strength; however, when the lap length was increased to a certain value, the increase in joint strength was not obvious.

The decomposition of the strain tensor into compression and tension parts was incorporated into this phase field method to improve the mechanical behaviors of the materials. These compression and tension strain parts are orthogonal in the context of the inner product in which the tensor of elastic stiffness behaves as a metric.

The influences of impact speed and gradient arrangement modes on the failure mode of the sandwich panels, the punch contact force (PCF) and the energy absorption effect (EAE) were investigated. It is found that the failure behavior of sandwich panels is different under different impact speeds. At the same impact speed, the thickness distribution pattern of the sandwich panel core layer will significantly affect the shock resistance of the panel.
