Quantitative reconstruction of defects in multi-layered bonded composites using fully convolutional network-based ultrasonic inversion

Jing Rao et al.

Summary: In this study, an ultrasonic method based on supervised fully convolutional network (FCN) is proposed to quantitatively reconstruct high contrast defects in multi-layered bonded composites. The FCN establishes a non-linear mapping from measured ultrasonic data to the corresponding longitudinal wave velocity models in the training process. The predicted FCN-based inversion method can accurately reconstruct ultrasonic longitudinal wave velocity models of high contrast defects, showing great potential for online detection of adhesively bonded composites.

Unravelling the interphase-bond strength relationship in novel co-bonded thermoplastic-thermoset hybrid composites for leading edge protection of wind turbine blades

Ozan Erartsin et al.

Summary: The relationship between the bond strength of co-bonded thermoplastics (ABS, PC) and fiber-reinforced thermoset polymers (polyester/glass) and the interphase morphology of a new integrated leading edge protection (LEP) solution for wind turbine blades has been investigated. Interphase morphology was analyzed using optical microscopy, while nanoindentation was used to determine the mechanical properties. Climbing drum peel tests were performed to measure the bond strength, and fractography was conducted to correlate fracture behavior with interphase morphology. The results showed that ABS exhibited a stronger bond with polyester/glass, making it a better choice as an LEP material. The superior bond strength of ABS was attributed to its higher affinity to polyester, resulting in a no-phase separated, tough interphase with extensive plastic deformation. In contrast, the interphase between PC and polyester/glass exhibited phase separation, leading to brittle failure at the interphase-polyester/glass interface.

A Spiral Graphene Framework Containing Highly Ordered Graphene Microtubes for Polymer Composites with Superior Through-Plane Thermal Conductivity

Jinrui Gong et al.

Summary: With the increasing power density of electronic devices, there is a growing demand for highly conductive polymer composites. Graphene, with its ultra-high thermal conductivity, is considered a promising filler to enhance the thermal conductivity of polymers. However, conventional mixing methods for preparing graphene-based polymer composites often result in limited thermal conductivity, due to the failure to create efficient heat transfer pathways in the polymer matrix. In this study, a spiral graphene framework was developed using a modified chemical vapor deposition method, which significantly improved the through-plane thermal conductivity of epoxy-based composites even at a low graphene loading of 0.86 wt%. Furthermore, the practical application of the composite in thermal management for light-emitting diodes (LEDs) was demonstrated.

Summary: Fused deposition modelling (FDM) is a fast-developing method for 3D printing polymers and composites. This study focused on using carbon nanotubes (CNTs) to improve the mechanical properties of 3D printed polyetherimide (PEI) composites. The results showed that the incorporation of CNTs significantly enhanced the bond strength and reduced porosity of the composites. Additionally, combining CNTs with annealing further improved the mechanical performance and reduced warping of the printed samples.

Co-curing bonding of carbon fibre/epoxy composite joints with excellent structure integrity using carbon fibre/PEEK tapes

Dong Quan et al.

Summary: A novel co-curing process using carbon fibre/PEEK tapes was proposed for bonding carbon fibre/epoxy composites, resulting in significantly improved structure integrity and thermal stability. The co-cured joints exhibited increased lap-shear strengths, extended fatigue life, and enhanced mode-I and mode-II fracture energies compared to joints bonded with traditional aerospace structural adhesives. The failure analysis revealed that plastic deformation, resin breakage, and carbon fibre delamination were the main failure mechanisms of the CF/PEEK bonded joints.
