Summary: Noise pollution poses a threat to health and well-being, and its prevalence has been increasing. Incorporating fluorescent single-walled carbon nanotubes (SWCNTs) into epoxy resins can improve their sound-dampening capabilities. The DNA-SWCNT/epoxy composites showed the highest transmission loss, with an 18% improvement compared to epoxy alone, and the optimal concentration of DNA-SWCNT was found to be 2 mg L-1. Additionally, the near-infrared fluorescence of SWCNTs was utilized to characterize their distribution within the epoxy resin.

Summary: Non-monotonic electrical resistance changes have been observed in multi-walled carbon nanotube (MWNT)/epoxy nanocomposites under tensile loading, but the mechanism is not fully understood. This study evaluates the impact of curing condition on the piezoresistivity of MWNT/epoxy nanocomposites, and suggests that a higher curing temperature can enhance the monotony of the piezoresistivity. The results indicate that the molecular structure of the polymer matrix contributes to the non-monotonic piezoresistivity of CNT/epoxy nanocomposites.

Summary: An efficient, lightweight and flexible electro-thermal system based on directly drawn carbon nanotube web was used for icing protection in aircraft structures. Impact damage on the heating elements was identified by an increase in electrical resistance and infrared imaging, with a novel methodology described for repairing and reconnecting the damaged CNT structure. Different layup arrangements of the CNT web exhibited varying degrees of resistance increase and loss of functionality, with a cross ply quasi-isotropic arrangement showing localized damage compared to the unidirectional arrangement.

Summary: This study investigates the hole making performance of thermoplastic carbon fibre/polyetherketoneketone (CF/PEKK) composite, comparing different methods (conventional drilling vs. helical milling) and feed rates. The research also reveals the effect of thermal-mechanical interaction on hole damage and utilizes advanced material characterization techniques to analyze material removal mechanisms and structural changes. Results show that delamination damage is influenced by machining temperature and thrust force, with helical milling generating higher temperatures and more severe microstructural damage compared to conventional drilling.

Summary: This study proposes a probability embedded approach for predicting the failure of IM7/8552 unidirectional carbon fibre reinforced polymer (CFRP) composite materials under biaxial stress states. The approach combines micromechanical modelling, artificial neural networks (ANNs), and uncertainty quantification. The ANN models show excellent performance in regression and classification problems, achieving low mean square error (MSE) and mean absolute error (MAE) for regression, and high prediction probability for classification. The failure strength predicted by the ANNs is in good agreement with the theoretically predicted failure envelopes.

Summary: This study investigates the effects of adding carbon fibers, infill pattern, and testing speed on the tensile and compressive behavior of 3D-printed parts. The results show that adding carbon fibers reduces variability and emphasizes print orientation. Aligning the infill pattern with the loading direction increases tensile strength, especially in carbon fiber-reinforced samples. The speed at which materials are strained during testing also affects the tensile and compressive strength, with higher speeds leading to increased strength in some samples.

Summary: This paper investigates the effect of impact damage on the fatigue behavior of CF/PEEK-titanium hybrid laminates. 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.
