Nowadays, natural fibers getting attention from researchers and industries to optimize the use it, with combination of polymers as composite structure, due to environmental awareness. Furthermore, it show a few advantage, such as biodegradability, light in weight and non-toxic characteristic. In this study, kenaf natural fibers was used as reinforcement material, with combination of polyester as matrix material, known as polymer matrix composites. The main purpose of this study is to analysis the mechanical properties of kenaf natural fiber/polyester composite structure, in order to know the suitability of kenaf natural fibers as replacement material for table tennis blade structure, instead of using wood. The structural panel of composite laminates has been produced using hand lay-up technique. The experimental works are performed in tension, impact (Charpy) and shear condition. The characteristic of different condition on kenaf composite structure was studied. Based on the result, it found the properties of kenaf composite structure, and it will used as a benchmark, to compare with initial properties of table tennis blade made by wood. In addition, the strength and a weakness of that particular materials and lamination structure will be identified.

“…Besides that, the main advantages of the honeycomb structures are light-weight, low density, high stiffness to weight ratio, high energy absorption and great anti-shock properties [8] , [9]. In this project, the square honeycomb structure is chosen because of the high energy absorption properties with minimum peak stress values compared to hexagonal and triangular honeycomb structures [10]. Besides that, the composite material is chosen because of the high strength to weight ratio, lightweight and fire resistance as well its wide usage in various sectors nowadays.…”

“…Chopped strand mat (CSM) is a discontinuous fibre while woven roving (WR) is a continuous fibre [25,27,28]. The two composites are formed when the fibre is bound with polyester resin or epoxy resin [10,23]. In this study, woven roving fiber is focused on and discussed in depth.…”

This paper investigates the compression properties of square honeycomb core materials based on glass fibre reinforced plastic. The objective of this project is to determine the failure strength and energy absorption of the square honeycomb structure and compare both crushing behaviours between the experimental and finite element simulations. Control specimen made from GFRP is prepared by using traditional hand lay-up technique and the mechanical properties are determined from the INSTRON Tensile Machine. In this study, the numerical simulation of the square honeycomb structure is analysed with the commercial software. In this simulation, the result obtained for maximum stress is 28.24MPa which is located at node 110451. Besides that, the energy absorption for finite element result and experimental result are 310.86 kJ and 282.17 kJ, respectively. The percentage of error is 9.23% which can be considered a good agreement between numerical simulation and experimental result. Lastly, the crushing behaviour between the finite element model and experimental model is slightly different to each other since the model in simulation is assumed to be the preferred structure, whereas the experimental model is imperfect in the geometric model.

Repair and restoration is an important step in remanufacturing as it ensures end-of-life products are returned to as-new condition before entering the subsequent life cycle. Currently, such processes are carried out manually by skilled workers. The advent of additive manufacturing (AM) has encouraged researchers to investigate its potential in automated repair and restoration, thus rendering it as a more effective method for remanufacturing. However, the application of this widespread technology for repair and restoration in remanufacturing is still new. This paper provides an overview of the principles and capabilities offered by the existing metal AM technology for object repair and restoration namely, direct energy deposition, powder bed fusion, and cold spray technology. Their applications in the repair and restoration of remanufacturable components are presented and discussed along with issues requiring attention from the perspectives of object design and process systems capabilities. The study provides a compilation of the challenges in AM repair and restoration, which primarily lie in the aspects of geometrical complexity, geometric dimensioning and tolerancing, material compatibility, and pre-processing requirements since it is critical for remanufacturing to restore end-of-life components to as new-condition. The paper concludes with suggestions for further works in AM restoration to enable product life cycle extension in the circular economy.
