Special Issue Information

Dear Colleagues,

Advanced composites have many advantages, such as a high specific strength, high specific modulus, fatigue resistance, light weight, corrosion resistance, strong design, etc. They have been widely investigated and applied in the aerospace field. The amount of composite materials used has become an important indicator for evaluating the advanced nature of aircraft or spacecraft. Composite materials and structures are formed simultaneously, which requires designers to have sufficient understanding of materials, preparation technology, mechanics, etc. Only in this way can we fully explore the potential of composite materials through an appropriate design. The extreme demands in the field of aerospace engineering create new challenges that are good opportunities for the development of advanced composite technology.

This Special Issue is on advanced composite design and manufacturing technology for aerospace engineering, with a main focus on materials, mechanics, manufacturing technology, test characterization, advanced equipment, engineering applications, etc. We encourage submissions of original research papers, short communications and review articles. This Special Issue will report on the latest progress regarding advanced composite technology in the aerospace field.

Potential topics for submissions include, but are not limited to:

  • Material design, such as fiber, resin, interfaces, functional materials, etc.;
  • Mechanical design, such as constitutive modeling, multiscale modeling, stiffness, static strength, fatigue, buckling stability, progressive damage behavior, etc.;
  • Manufacturing technology, such as autoclave, RTM, additive manufacturing, intelligent manufacturing, etc.;
  • Advanced equipment, such as automatic molding, additive manufacturing, test characterization, nondestructive testing, etc.;
  • Engineering applications, such as composite products, high-performance materials, design and evaluation methods, etc.

Experimental methodologies for fatigue lifetime prediction are time-intensive and susceptible to environmental variables. Although the cohesive zone model is popular for predicting adhesive fatigue lifetime, entropy-based methods have also displayed potential. This study aims to (1) provide an understanding of the durability characteristics of carbon fiber-reinforced plastic (CFRP) adhesive joints by incorporating an entropy damage model within the context of the finite element method and (2) examine the effects of different adhesive layer thicknesses on single-lap shear models. As the thickness of the adhesive layer increases, damage variables initially increase and then decrease. These peak at 0.3 mm. This observation provides a crucial understanding of the stress behavior at the resin–CFRP interface and the fatigue mechanisms of the resin. Full article

In the face of the difficulty in achieving high-quality integrated molding of longitudinally and transversely stiffened panels for helicopters by resin-matrix composite materials, we combine the prepreg process and the resin transfer molding (RTM) process to propose a hybrid resin transfer molding (HRTM) for composite stiffened panel structures. The HRTM process uses a mixture of prepreg and dry fabric to lay up a hybrid fiber preform, and involves injecting liquid resin technology. Using this process, a longitudinally and transversely stiffened panel structure is prepared, and the failure modes under compressive load are explored. The results show that at the injection temperature of the RTM resin, the prepreg resin dissolves slightly and has little effect on the viscosity of the RTM resin. Both resins have good miscibility at the curing temperature, which allows for the overall curing of the resin. A removable box core mold for the HRTM molding is designed, which makes it convenient for the mold to be removed after molding and is suitable for the overall molding of the composite stiffened panel. Ultrasonic C-scan results show that the internal quality of the composite laminates prepared using the HRTM process is good. A compression test proves that the composite stiffened panel undergoes sequential buckling deformation in different areas under compressive load, followed by localized debonding and delamination of the skin, and finally failure due to the fracture of the longitudinal reinforcement ribs on both sides. The compressive performance of the test specimen is in good agreement with the finite element simulation results. The verification results show that the HRTM process can achieve high-quality integrated molding of the composite longitudinally and transversely stiffened panel structure. Full article
