Special Issue Information

Dear Colleagues,

It is widely known that the performance and service life of fiber-reinforced resin–matrix composites are closely related to intrinsic material properties, fabrication processes, structural design, and environmental application. But how do these factors influence the static load-bearing capacity and service life of fiber-reinforced resin–matrix composites? How can numerical analysis be employed to identify the key influencing factors, and how do these factors affect the mechanical behavior of composite structures? These are the key issues explored in this Special Issue. We welcome the submission of original research articles and reviews that discuss areas including (but not limited to) the following:

1) The Numerical Investigation of Mechanical Properties of Novel Composite Materials

  • Novel composite materials comprising thermoplastic matrix materials, modified thermosetting matrix materials, and reinforced carbon/glass fibers;
  • Mechanical properties comprising static/dynamical impact and fatigue mechanical properties;
  • Multiscale characterization testing methods and multiscale numerical analysis methods.

2) Composite manufacturing monitoring and process optimization

  • The numerical modeling of curing distortion of composite structures;
  • The safety performance evaluation of composite structures with thermal residual stresses;
  • An evaluation of the residual carrying capacity of composite structures with manufacturing defects.

3) Composite structure optimization design and reliability analysis

  • Advanced numerical analysis methods for composites, such as modified cohesive element, extended finite element, the RVE analysis method, etc.;
  • Reliability analysis and the assessment of composite structures considering the damage tolerance of composites.

4) Applications of advanced composite materials in extreme environments

  • The dynamic analysis and modeling of composite aircraft during ditching;
  • Crashworthiness analysis and the evaluation of composite aircraft;
  • Pyrolytic analysis and the residual bearing capacity of composites.

5) Deformation reconstruction and load identification of composite structures

  • High-capacity optical fiber arrays for high-precision strain monitoring technology;
  • Displacement field reconstruction technology based on inverse finite element;
  • High-precision load identification technology based on deep learning.

We look forward to receiving your contributions.

Abstract
The failure behaviors of CFR–aluminum lap joints with diverse configurations through quasi-static tensile tests were conducted at −40 °C, 25 °C, and 80 °C. Four specimen types were examined: CFRP–aluminum alloy two-bolt single-lap joints (TBSL), two-bolt double-lap joints (TBDL), two-bolt bonded–bolted hybrid single-lap [...] Read more.
The failure behaviors of CFR–aluminum lap joints with diverse configurations through quasi-static tensile tests were conducted at −40 °C, 25 °C, and 80 °C. Four specimen types were examined: CFRP–aluminum alloy two-bolt single-lap joints (TBSL), two-bolt double-lap joints (TBDL), two-bolt bonded–bolted hybrid single-lap joints (BBSL), and two-bolt bonded–bolted hybrid double-lap joints (BBDL). The analysis reveals that double-lap joints possess a markedly higher strength than single-lap joints. The ultimate loads of the TBSL (single-lap joints) at temperatures of −40 °C and 25 °C are 29.5% and 26.20% lower, respectively, than those of the TBDL (double-lap joints). Similarly, the ultimate loads of the BBSL (hybrid single-lap joints) at −40 °C, 25 °C, and 80 °C are 19.8%, 31.66%, and 40.05% lower, respectively, compared to the corresponding data of the TBDL. In bolted–bonded hybrid connections, the adhesive layer enhances the joint’s overall stiffness but exhibits significant temperature dependence. At room and low temperatures, the ultimate loads of the BBDL are 46.97 kN at −40 °C and 50.30 kN at 25 °C, which are significantly higher than those of the TBDL (42.24 kN and 44.63 kN, respectively). However, at high temperatures, the load–displacement curves of the BBDL and TBDL are nearly identical. This suggests that the adhesive layers are unable to provide a sufficient shear-bearing capacity due to their low modulus at elevated temperatures. This research provides valuable insights for designing composite–metal connections in aircraft structures, highlighting the impacts of different joint configurations and temperature conditions on failure modes and load-bearing capacities.
