Summary: Basalt fibre (BF) is a promising natural reinforcing material for polymer composites, and when modified with nanofillers like graphene nanoplatelets (GNP) and nanosilica (NS), it shows enhanced mechanical properties. The incorporation of hybrid nanofillers contributes to the improvement in the mechanical properties of the composites, especially in terms of modulus and strength. This study demonstrates the potential of BF as an alternative to synthetic glass fibre for mechanical components and structures.

Summary: Implantable electronic devices (IEDs) are widely used for medical treatment and diagnosis. The ideal encapsulation of IEDs remains a challenge, but in this study, a high-performance composite coating was developed by incorporating SiO2 nanoparticles into silicone rubber, resulting in improved mechanical properties and barrier performance. The composite coating with 3% nanosilica content demonstrated optimal combination of enhanced fracture strength, increased coating resistance, and ideal coating uniformity. The modified SiO2 particles with enriched methyl groups exhibited strong bridging effects and anti-agglomeration property, leading to significant improvements in the mechanical performance of nanosilica-filled silicone rubber. The as-fabricated nanosilica-filled silicone rubber showed superior protection for the encapsulated circuits compared to pure silicone rubber and bare circuit boards.

Summary: The aim of this study was to investigate the effect of fiber's chemical surface treatments on the thermal and mechanical performance of PP in the development of a new bio-composite. The results showed that the addition of fibers reduced the thermal stability of the reinforced PP, but improved its Yung's modulus, tensile strength, and hardness. However, the elongation at break and toughness of the reinforced composites were decreased compared to neat PP. These findings highlight the advantages of using thermoplastic matrix reinforced with cellulosic fibers.

Summary: We conducted a comparative study on the molecular dynamics of epoxy nanocomposites filled with different types and crystallinity of silica-based nanoparticles. We observed various well-known relaxations and discovered a new relaxation process that is inversely correlated to the crystallinity of the nanoparticles. Additionally, two weaker interfacial polarization relaxations were observed in core-shell structures.

Summary: The increase in SEBS-g-MA concentration and decrease in SBS:SEBS-g-MA weight ratio improved the dispersion of PBT domains in the blend, leading to enhanced mechanical properties such as Young's modulus, yield stress, tensile strength, and tensile ductility. The improvement in mechanical properties was attributed to better blend compatibility and interfacial adhesion as well as a more homogeneous mixing state between blend components.

Summary: The electrospray deposition technique was used to uniformly coat carbon nanotubes on the surface of glass fiber to enhance the flexural strength of composite laminate. Optimizing the deposition of CNTs on the GF surface led to significant improvements in the flexural performance of the composite laminate, with well-dispersed and homogeneous coatings observed. The applied voltage and spray time were found to affect the dispersion of CNTs and the flexural output, respectively.

Summary: This study investigated the effect of hybrid fillers on the mechanical and wear performance of polymer composites. The results showed that the composite filled with a hybrid filler synthesized via chemical vapour deposition method had better wear resistance and lower coefficient of friction compared to the composite filled with a physically hybrid filler. The wear resistance and coefficient of friction of the composites were in the order of HYB composite < PHY composite < pure phenolic under different sliding speeds and applied loads.

Summary: The aim of this study was to evaluate the effect of reprocessing on the service life properties of polypropylene wastes reinforced with E-glass fiber. The results showed that the properties of the composites decreased with successive reprocessing, including reduced thermal stability, crystallinity, molecular weight, and complex viscosity. Therefore, reinforced in-house PP plastics can only be reprocessed twice, unless virgin PP or other materials are added to compensate for the lost properties.
