Summary: Traditional composite laminated structures lack reinforcements in the thickness direction between the laminae and microfibers, resulting in poor interaction and weak load transfer. This research demonstrates that using helical carbon nanotubes (HCNTs) as nanoscale reinforcement can substantially improve the performance of polymeric resins. The nanocomposite laminates fabricated with HCNTs showed significant improvements in tensile strength, modulus, and strain-to-failure.

Summary: This study utilized polarized Raman spectroscopy to assess the strain in aligned multi-walled carbon nanotube/epoxy composites, aiming to clarify the effective elastic modulus of the carbon nanotubes. The Raman shift rate of the G' band of the carbon nanotubes was found to be 18.84 cm(-1)/% corresponding to the tensile strain of the composite specimen. Through Mori-Tanaka theory and consideration of the three-dimensional orientation distribution of the carbon nanotubes, the effective elastic modulus of the carbon nanotubes was estimated to be 400 GPa. The results demonstrated the utility of Raman spectroscopy in experimentally evaluating the effective elastic modulus of multi-walled carbon nanotubes in composites.

Summary: In fiber-reinforced polymer composite manufacturing, frictional behavior plays a crucial role in determining the quality of the manufactured parts. By conducting frictional sliding rheometry tests, researchers were able to accurately characterize the tool-ply friction and investigate the effects of processing parameters on frictional response. The results showed that increasing temperature reduced frictional forces due to increased resin flowability, while increasing sliding rates significantly increased frictional forces. The influence of applied load on frictional characteristics was more complex, involving contributions from adhesive and normal forces. Contact area measurements at different temperatures, normal forces, and sliding rates provided insights for interpreting the results.

Summary: Current research is focused on developing buoyant nanocomposite foams using naturally available nanofiller-halloysite nanotubes (HNTs). Cenosphere, a waste byproduct of thermal power plants, is used to make lightweight syntactic foam composites in an epoxy matrix. HNTs are added to improve the mechanical and water absorption properties of the composites. Compression tests on samples immersed in water show that HNTs inhibit water entry into the epoxy matrix, resulting in lower absorption values. This research demonstrates the potential of HNTs as a structural, buoyant, and lightweight syntactic nanocomposite foam for maritime applications.

Summary: Plastic-contaminated drinking water is a global concern, with a focus on microplastics contamination in a conventional water treatment plant in Thailand. The study found that the water treatment plant had an overall removal efficiency of 67.6% to 57.2%, with a substantial number of microplastics still present in the treated water. The dominant sources of microplastics contamination were identified as raw water and internal contamination within the plant, posing a challenge to drinking water quality in Thailand.
