  • effect of polybutylene terephthalate pbt on impact property improvement of hybrid kenaf glass epoxy composite
    Materials Letters, 2012
    Co-Authors: M M Davoodi, S M Sapuan, Desa Ahmad, A Aidy, A Khalina, Mehdi Jonoobi
    Abstract:

    Environmental regulations, costs and lightweight encourage car manufacturers to develop new reliable Products. Epoxy provides a reliable fibre impregnation and creates substantial three-dimensional (3D) cross-linking for proper load transmission and impact strength improvement, but their low toughness decreases their energy absorption. Thermoplastic toughening improves the epoxy impact property with a low thermo-mechanical defect. This study, focused on improving the impact property of hybrid kenaf/glass fibre epoxy composite by use of a modified sheet moulding compound (GMT). The results indicated that most of the mechanical properties of developed material were almost the same as those of the GMT, except impact. This result highlights the potential for utilisation of the toughened hybrid bio-composite in some automotive structural components. Moreover, geometric parameters, e.g., cross-section, thickness, and reinforcement ribs suggest an improvement of structural impact resistance to comply with the bumper beam Product Design Specification (PDS).

  • concept selection of car bumper beam with developed hybrid bio composite material
    Materials & Design, 2011
    Co-Authors: M M Davoodi, S M Sapuan, Desa Ahmad, A Aidy, A Khalina, Mehdi Jonoobi
    Abstract:

    Abstract Application of natural fibre composites is going to increase in different areas caused by environmental, technical and economic advantages. However, their low mechanical properties have limited their particular application in automotive structural components. Hybridizations with other reinforcements or matrices can improve mechanical properties of natural fibre composite. Moreover, geometric optimizations have a significant role in structural strength improvement. This study focused on selecting the best geometrical bumper beam concept to fulfill the safety parameters of the defined Product Design Specification (PDS). The mechanical properties of developed hybrid composite material were considered in different bumper beam concepts with the same frontal curvature, thickness, and overall dimensions. The low-speed impact test was simulated under the same conditions in Abaqus V16R9 software. Six weighted criteria, which were deflection, strain energy, mass, cost, easy manufacturing, and the rib possibility were analyzed to form an evaluation matrix. Topsis method was employed to select the best concept. It is concluded that double hat profile (DHP) with defined material model can be used for bumper beam of a small car. In addition, selected concept can be strengthened by adding reinforced ribs or increasing the thickness of the bumper beam to comply with the defined PDS.

  • Design and fabrication of kenaf fibre reinforced polymer composites for portable laptop table
    2018
    Co-Authors: S M Sapuan, K R Purushothman, M L Sanyang, Muhd Ridzuan Mansor
    Abstract:

    Natural fibre is an emerging material that can help to reduce the dependency on non-renewable resources and sustains the ecological balance. This research focuses on the Design and fabrication of a laptop table using kenaf fibre reinforced polymer composite. A composite portable laptop table was developed using standard Design method and the manufacturing method used was hand lay-up. Market investigation, Product Design Specification, conceptual Design, detail Design followed by fabrication were performed accordingly throughout this project. Stress distribution and deformation of the end Product was tested using simulation software. This research has enabled to produce a strong, stable and aesthetic furniture which is made from composite material.

  • implementation of the expert decision system for environmental assessment in composite materials selection for automotive components
    Journal of Cleaner Production, 2015
    Co-Authors: B Ahmed A Ali, S M Sapuan, E S Zainudin, Mohamed O Othman
    Abstract:

    Abstract Conventional materials selection system was replaced with sophisticated software tools by rapid changing technology. The growing environmental concerns and regulations widely among the industry, especially in automobiles, force us to explore the natural fiber materials as a replacement for synthetic materials which is in common use. As a result of extensive research and development, new natural fiber reinforced composite materials are emerging and the database of materials growing exponentially. The decision of selecting optimized materials was complicated, as it involves diversified choice of materials, coupled with various influencing criteria for the selection process. To abstain from deciding inappropriate materials, the technology of expert system software tools can help us in the appropriate materials selection. The objective of this research was to explore the implementation of Analytical Hierarchy Process (AHP) using the expert choice software tool for deciding optimum natural fiber reinforced composite materials by considering main criteria and sub-criteria in the hierarchical model. The final judgement was performed with different scenarios of sensitivity analysis, giving priority to the environmental factors and sustainability. The result shows that the natural fiber composite material hemp and polypropylene gained the higher rank in the selection process and almost compliant with the requirements of industrial Product Design Specification and can be recommended to automotive component manufacturers to enforce green technology.
