“…Samples were divided into seven groups and immersed in deionized water at 80 • C. The aging time of the seven groups was 0, 7,14,21,28,35, and 42 days, respectively. After hydrothermal aging, specimens were taken out and dried for 24 h at 25 • C.…”

Carbon fiber reinforced polycarbonate (CF/PC) composites have attracted attention for their excellent performances. However, their performances are greatly affected by environmental factors. In this work, the composites were exposed to hydrothermal aging to investigate the effects of a hot and humid environment. The mechanical properties of CF/PC composites with different aging times (0, 7, 14, 21, 28, 35, and 42 days) were analyzed. It was demonstrated that the storage modulus of CF/PC composites with hot water aged for seven days has the highest value in this sampling period and frequency. Through the solid particle erosion experiment, it was found that the hydrothermal aging causes the deviation of the maximum erosion angle of composites, indicating the composites underwent ductile–brittle transformation. Furthermore, the crack and cavity resulting from the absorption of water was observed via the scanning electron microscope (SEM). This suggested that the hydrothermal aging leads to the plasticization and degradation of CF/PC composites, resulting in a reduction of corrosion resistance.

“…It is worth noting that load-displacement data were easier to measure experimentally and thus chosen to provide possible validation between the experimental results and the developed modeling technique. This yields to our discussions using structural total energy, rather than dissipated energy which provides clearer evaluation on the fracture behaviors of the component during axial crushing [5,8,[24][25][26]. The total EA during the entire crushing process is obtained through integrating the crushing force (F) with the corresponding distance (s) as in Equation 3.…”

“…Carbon fiber-reinforced plastic (CFRP) is commonly favored by automobile manufacturers due to the advantages in high specific modulus, specific energy absorption (EA), low density and easy forming, etc., and has thus become an important option to realize lightweight in vehicle body design in the future [4][5][6]. In addition to the superior specific stiffness and specific strength [7][8][9], CFRP has also shown good corrosion resistance [10], crush and impact resistance [11,12], and noise reduction property [13], and thus their applications become increasingly attractive in many fields, including automotive industry, aerospace, marine, etc.…”

Adhesive bonding is widely used in structural connection of composite components due to its capacity to effectively avoid inducing stress concentration and damage in composite components. This work applies a design optimization methodology on the geometry of cross section and ply thickness in adhesively bonded CFRP (carbon fiber-reinforced plastic), hat-shaped, thin-walled beam in automobiles to achieve car body lightweight design. A multi-objective and multi-constraint design optimization problem was formulated to find the optimum key cross-section size and ply thickness of the hat thin-walled beam. The minimum total material cost and maximum energy absorption (EA) during the axial crushing test of the CFRP beam were selected as the optimization objectives. The non-dominated sorting genetic algorithm II (NSGA-II) was introduced to search for global optimum solution, and radial basis function (RBF) approximations for the objective functions were applied to reduce the computational cost. It was revealed that EA increased by 8.28%, while the total weight and cost decreased by 3.14% and 3.23%, respectively, and can thus provide a guidance in vehicle composite component design.
