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.

“…One of the most common methods for weight reduction while maintaining its strength is to embrace composite protection panel. The design of laminate must retain the original strength, while reducing the weight of panel [14][15][16]. As studied, the front material of protection panel must consist of high hardness, whilst the back plate has high ductility.…”

This paper present the study about the mechanical properties of two high strength low alloy steels for replacing the current rolled homogeneous armour (RHA) for ballistic application. High strength low alloy steel has been widely adapted as a ballistic plate in light armoured vehicle. However, the current used RHA plate is very heavy thus restricted the manoeuvrability of the armoured vehicle. The aim of this study is to find materials suitable to be used for production of composite protection panel which is lighter yet has similar mechanical properties to RHA. The tensile strength and hardness of AISI 4340 and AR500 steels were evaluated and compared to that of RHA and the results were analysed based on its chemical compositions and microstructural observation. Values of these properties are primarily reflected by its microstructures and chemical compositions. Therefore, microscopic observation of microstructural arrangement and phases are essential in understanding the hardness and stress-strain behaviour of these metals. Results indicate similar tensile properties were observed in RHA and AR500 but different properties obtained for AISI 4340. Tensile strength of RHA and AR500 were 1750 MPa and 1740 MPa respectively followed by AISI 4340 at 1020 MPa. AISI 4340 steel exhibited the highest elongation at 20.6% compared to RHA and AR500 at 13.3 and 12.5%, respectively. Higher degree of carbon content in fine martensitic structure of RHA and AR500 led to high hardness. Imperfections in RHA and AR500 were also removed by hot rolling process as indicated by white banding that cause higher in tensile strength. Retained austenite and coarse microstructure of AISI 4340 steel contributed to higher ductility compared to AR500 and RHA. Therefore the tensile properties of RHA and AR500 were found similar due to its microstructure behaviour. This similarity allows AR500 to be utilised as alternatives to RHA in armour plate application.

This paper presents the perforation behaviour of polyethylene terephthalate (PET) foam cored sandwich structures when subjected to quasi-static and dynamic loading at normal (0°) and oblique angles of 10° and 20°. An instrumented drop-weight hammer rig was used with fully-clamped conditions for the low-velocity impact test with impact energy of 40 J and velocity of 3.78 m/s. Meanwhile, the quasi-static indentation test was carried out using a universal testing machine via an Instron 4505, at crosshead displacement rate of 1 mm/min, with boundary conditions similar to those of the dynamic test. Results obtained showed that the normal impact generated the highest peak force for both the first and second peaks, which are associated with the damage to the top and bottom skins of the sandwich structures. Moreover, regardless of whether the test was done on the normal or inclined angles, it was observed that the dynamic loading produced higher force magnitude in comparison to those of the quasi-static response, due to the enhanced strength and stiffness of the components because of the strain rate and inertia effects. However, in terms of the damage profiles, it is evident that the maximum damage area increased with the increase inclination angle as supported by simple geometric analysis. For the oblique impact cases, the damage was due to the combined effect of tensile, compression, and shear for impact at 10°. The damage occurred as a result of pure shearing for the 20° impact case. In conclusion, the perforation behaviour at inclined angles allowed more area to be perforated in comparison to those of the normal cases.
