    Deflection-Based Numerical Evaluation of Steel, Bamboo Fibre, and Carbon Fibre Polymer Reinforced Portal Frame by S.O Odeyemi, M.A Olawale, M.O Adisa, O.D Atoyebi, Z.T Giwa

    Published 2024-06-01
    “…This study aims to compare numerically the deflection resistance of portal frames reinforced with steel, bamboo fibre, and carbon fibre polymers using Abaqus version 6.14. The replacement of steel with carbon fibre within the portal frame exhibited comparable effectiveness to that of utilizing steel, whereas the introduction of bamboo fibre was observed to yield relatively diminished efficacy. …”

    Effect of Multiwalled Carbon Nanotubes and Electroless Copper Plating on the Tensile Behavior of Carbon Fiber Reinforced Polymers by Gia Toai Truong, Jiho Kim, Kyoung-Kyu Choi

    Published 2018-01-01
    “…Multiwalled carbon nanotubes (MWCNTs) and nanoscaled electroless copper plating were introduced to enhance the mechanical properties of carbon fiber reinforced polymer (CFRP) composites in this study. The influence of multiwalled carbon nanotubes (MWCNTs) with weight fractions of 0.5–1.5% of epoxy resin on the mechanical properties of CFRP composites was investigated. …”
