“…When the lap length is important, the defects have less effect on the strength of the joint. Moreover, previous studies [24][25][26] on composite surface treatment methods include examinations of mechanical treatment, peel-layer technology and laser treatment, focusing on optimizing the process parameters to improve the composite surfaces in order to enhance the bond strength and fracture toughness of the bonded joints. However, few studies have comprehensively investigated and analyzed the effect of the area ratio, location, morphology and penetration of the defects as relevant variables on the model of joint failure.…”

Due to their mechanical load-bearing and functional wave transmission, adhesively bonded joints of carbon fiber–quartz fiber composites have been widely used in the new generation of stealth aviation equipment. However, the curing defects, caused by deviations between the process environment and the setting parameters, directly affect the service performance of the joint during the curing cycle. Therefore, the thermophysical parameter evolution of adhesive films was analyzed via dynamic DSC (differential scanning calorimeter), isothermal DSC and TGA (thermal gravimetric analyzer) tests. The various prefabricating defects within the adhesive layer were used to systematically simulate the impacts of void defects on the tensile properties, and orthogonal tests were designed to clarify the effects of the curing process parameters on the joints’ bonding performance. The results demonstrate that the J-116 B adhesive film starts to cure at a temperature of 160 °C and gradually forms a three-dimensional mesh-bearing structure. Furthermore, a bonding interface between the J-116 B adhesive film and the components to be connected is generated. When the curing temperature exceeds 200 °C, both the adhesive film and the resin matrix thermally degrade the molecular structure. The adhesive strength weakens with an increasing defect area ratio and number, remaining more sensitive to triangle, edge and penetration defects. By affecting the molecular structure of the adhesive film, the curing temperature has a significant impact on the bonding properties; when the curing degree is ensured, the curing pressure directly impacts the adhesive’s performance by influencing the morphology, number and distribution of voids. Conversely, the heating rate and heat preservation time have minimal effects on the bonding performance.

“…The design of experiments (DOE) is an efficient approach for studying the effect of control parameters and their interaction on the performance of the process output. 21,22 The traditional experimental technique is challenging, mainly when many experimentations and process parameters are required. 23,24 The essential step in the DOE is setting the control parameters.…”

The present work studies the mechanical alloying, consolidation, evaluation, modeling, and optimization of the Al-TiC composites mixed at different milling times (MTs) of 6, 12, 24, and 48 h and reinforced with three TiC concentrations (3, 6, and 12 vol.%). The Al-TiC composites formed via the powder metallurgy method. The XRD of the mixed powder and the consolidated composites were investigated. Furthermore, density, wear, compressive strength, and hardness have been examined for the consolidated composites. Also, the worn surface of the wear-tested composites was studied utilizing SEM analysis. The response surface methodology (RSM) was involved to clarify the effects of mechanical alloying parameters of MTs and the TiC concentrations and their interaction towards achieving their optimum process factors to produce Al-TiC composites. The RSM results prove the applied factors’ importance in improving the consolidated composites’ properties. The optimization results show the optimum parameters to produce Al-TiC composites are 28.4 MTs and 12 vol.% TiC to produce Al-TiC composites with 304.4 ± 3 MPa compressive strength, 191.21 ± 2 HV hardness, 2.88 ± 0.008 g/cm3 density, and 9.7 ± 0.01 mg weight loss. The ANOVA analysis reveals that the suggested models can virtually expect the tested responses of density, hardness, compressive strength, and weight loss with a confidence level of over 90, 98, 95, and 95%, respectively.
