Special Issue Information

Dear Colleagues,

Polymer composites, combining synthetic or natural polymer matrices with high-performance reinforcements such as fibers, particles, and nanomaterials, have become indispensable in aerospace, transportation, civil infrastructure, energy systems, biomedical devices, and environmental engineering. Their outstanding characteristics—including high specific strength and stiffness, superior corrosion resistance, lightweight design, and tailored multifunctionality—make them ideal for advanced structural and functional applications.

This Special Issue aims to highlight the latest advances in the design, processing, characterization, and modeling of polymer composites, with particular emphasis on multifunctionality, durability, and structural integrity under diverse service conditions. We welcome contributions that explore novel material systems, advanced manufacturing processes, innovative performance enhancement strategies, and emerging nondestructive evaluation (NDE) and structural health monitoring (SHM) techniques. Studies focusing on computational modeling, data-driven performance prediction, and the integration of intelligent sensing technologies into polymer composites are also encouraged.

Topics of interest include, but are not limited to, the following:

  • Development of high-performance polymer matrices and fiber reinforcements with enhanced mechanical, thermal, and functional properties.
  • Advanced fabrication technologies for polymer composites (e.g., additive manufacturing, automated fiber placement, hybrid manufacturing, 3D weaving/braiding).
  • Integration of nanomaterials, smart fillers, or functional coatings for improved sensing, self-healing, energy harvesting, or environmental adaptability.
  • Interface engineering, damage tolerance, fatigue resistance, and multifunctional performance optimization.
  • Nondestructive testing (NDT) and SHM methods for real-time monitoring and life prediction of polymer composites.
  • Sustainable and recyclable polymer composites, including biodegradable and renewable material systems.
  • Multi-scale experimental, theoretical, and computational modeling for performance evaluation.

Carbon Fiber Reinforced Polymers (CFRP) are extensively utilized in high-performance engineering, yet localized structural discontinuities can severely compromise their integrity. This paper aims to achieve high-sensitivity characterization of such anomalies using a proposed acoustic shearography technique based on continuous acoustic excitation. A comprehensive finite element model (FEM) was developed to clarify the mechanical-energy coupling between the acoustic fields and localized surface strain field modulations. By exploiting ultrasonic energy coupling, the localized features of discontinuities were identified through full-field, non-contact optical measurement of localized phase distortions. Key parameters, including shearing amount, excitation frequency, driving voltage, and geometric characteristics of blind flat-bottom holes (BFBH), were systematically investigated. The results demonstrate a high correlation between FEM simulations and experimental observations quantitatively elucidating how defect diameter and hole depth modulate surface strain distributions. The proposed hybrid acoustic optical approach achieves near-instantaneous full field imaging within a millisecond timeframe typically under 200 ms. Additionally, the methodology leverages localized acoustic resonance to significantly boost the signal-to-noise ratio (SNR) resulting in highly quantified phase map contrast. Full article

Lattices have attracted increasing attention for their outstanding mechanical and multifunctional properties. In this study, a novel class of hybrid lattices composed of Primitive (P) and I-Wrapped Package (W) topologies is proposed by a mathematical formula. The deformation behaviors, mechanical properties, and energy absorption characteristics of the hybrid lattices are systematically investigated using compression experiments and simulations. The results show that the hybrid lattices exhibit a localized initial failure followed by stress redistribution, effectively avoiding brittle interlayer collapse of the P-type sub-lattices and maintaining a high load-bearing capacity even after the initial failure. A synergistic enhancement effect of ‘1 + 1 > 2’ is observed, in which the hybrid lattices outperform the linear combination of their constituent sub-lattices. Compared with the total performance of the P and W sub-lattices, the hybrid lattices exhibit increases of 11.6%, 30.0%, 34.5%, and 368% in elastic modulus, yield strength, compressive strength, and energy absorption, respectively. The exceptional energy absorption capability of hybrid lattices is attributed to the synergistic deformations and stress redistribution mechanisms during the compression. The proposed hybrid lattices significantly improve energy absorption, and they have potential applications in a tunnel lamp maintenance robot. Full article
