Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.

Summary: This study focuses on the functionalization and distribution of conductive fillers, as well as the interfacial compatibilization of polymer blends, in order to improve the electrical conductivity and electromagnetic interference shielding efficiency of composites. By modifying the carbon nanotubes (CNTs) with an ionic liquid copolymer and controlling the blending process, selective localization of CNTs at the interphase and the formation of effective conductive networks at the interface were achieved. This resulted in a significant increase in electrical conductivity and a maximum EMI shielding efficiency of 41 dB for the PLA/PCL/PIL/CNT composites.

Summary: This study presents a nature-inspired interface strategy to fabricate high-performance and low-cost fiber-reinforced composites. By coating a heterostructural montmorillonite-multiwalled carbon nanotube (Mt-MWCNT) hybrid on the surface of glass fibers, a nacre-like interface layer is formed, improving the strength and toughness of the glass fiber/ epoxy composites. The enhanced dispersion and strong bonding of the Mt-MWCNT hybrids contribute to the improvement in interlaminar shear strength, work of break, storage modulus, and thermal stability of the resulting composites.

Summary: The demand for high thermal conductivity has led to the development of materials that can efficiently manipulate thermal energy. Polymer-based composites on hexagonal boron nitride (h-BN) are effective for providing thermally conductive and electrically insulating pathways, but it is difficult to establish strong interfacial connections within polymer chains using BN alone. In this study, hydroxylation of h-BN and carbon nanotubes (CNT) was achieved, followed by the formation of a urethane crosslink between the filler-filler interfaces and thermoplastic polyurethane (TPU) matrix. This unique hybrid structure achieved an unprecedented thermal conductivity of 4.52 Wm-1K-1 at just 60 wt% loading of h-BN and 2 wt% of CNT, as well as outstanding yielding strength and Young's modulus by tension.

Summary: In this study, ternary silicone dielectric elastomer micro-nanocomposites were prepared by incorporating barium titanate (BT) nanoparticles or Si747-modified BT (BT-Si747) and hexagonal boron nitride (BN) microplatelets into methyl vinyl silicone rubber (MVSR). The addition of BN platelets as physical barriers improved the dispersion of BT nanoparticles, leading to higher electric breakdown field in the composites. The use of Si747 enhanced interfacial interaction and mechanical properties of the composites, resulting in higher tensile strength and elongation at break compared to composites without Si747. The prepared MVSR/BT-Si747/BN composites showed improved actuation performance under lower electric fields, making them promising for applications in dielectric actuators.

A fatigue life model is proposed to predict the S-N curves of the laminates based on energy dissipation approach. The energy dissipation behavior of the laminates under different experimental conditions is analyzed through post-impact fatigue tests, and the correlation between impact damage and fatigue dissipation energy is determined. The validity of the proposed model is verified through fatigue tests under different stress ratios and impact energy levels.
