Abstract
This research investigated the lattice structure fabricated using corn husk fibre reinforced recycled polystyrene composite using Finite Element Analysis (FEA). The material’s properties of this composite material were obtained from previous study. Then, the lattice structure of lattice structure was created using Creo® software and the FEA simulation was done by ANSYS software. In this study, the lattice structures were created using triangular prism and hexagonal prism. The analysis was divided into two conditions: 1) lattice structure with different prism shape and similar surface area, 2) lattice structure with varies of strut thickness and 3) lattice structure with different prism shape and similar lattice parameter. The results show the lattice structure with triangular prism have more structural integrity than hexagonal prism. Then, lattice structure with triangular prism can be built with lesser material but stronger and stiffer than lattice structure with hexagonal prism.
Highlights
In this modern era, natural fibre-reinforced polymer composite (NFRPC) is widely used in many applications such as in automobiles, civil construction and aircraft [1,2]
The lattice structure with triangular prism experienced less maximum normal stress compared to lattice structure with normal stress
As the struct thickness increases, the lattice structure with triangular prism experience lesser deduction in maximum normal stress and maximum total deformation compared to lattice structure with hexagonal prism
Summary
Natural fibre-reinforced polymer composite (NFRPC) is widely used in many applications such as in automobiles, civil construction and aircraft [1,2]. NFRPC is generally a material that is combination of natural fibres and polymer matrix either to thermoplastic or thermoset and they can be produced via conventional polymer manufacturing process such like injection molding and compression molding [3,4]. A NFRPC material was made from recycled polystyrene and corn husk fibre via compression moulding method [5]. The similar composite material made into FDM filament and used for FDM printing. The 3D printed components with this composite material exhibited a good mechanical strength and high stiffness as compared to commercial plastic filament [6].
