On the other hand, lightweight vehicles typically have crashworthiness concerns. Vehicle crashworthiness is becoming very critical for electric vehicle due to potential for high voltage shortage and thermal issues of the battery system. Composite materials can become an option to fulfill the lightweight structure requirements because of strength to weight ratio higher than common metallic materials. In the developments of electricity vehicles, composite materials can be the first option to protect the structure from shortage issues. This research studied the experimental and numerical analysis of composite based crashbox structures. The crashbox was made of carbon fiber reinforced polymer composite (CFRP) with the double hat thin-walled constructions. The simulation and experimental studies of the crashbox was done under the axial crushing load. Specimens were made with various thicknesses and various number of layers. The crashworthiness simulation of the composite based crashbox structure shows good agreement with experimental results. The simulation was done by using LS-Dyna code, and damage kinematics was able to be replicated by adjusting critical parameters of DFAIL and SOFT.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Axial impact,Carbon fiber reinforced polymer composite,Crash box,Experimental and numerical analysis,Light-weight constructions,Lightweight structure designs,MAT54,Strength to weight ratio[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]axial impact,CFRP,crashbox,crashworthiness,MAT54[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]ACKNOWLEDGEMENT This research was supported by the Ministry of Research, Technology and Higher Education of Indonesia under the research project “Modeling and analysis of composite structure for lightweight structure applications under dynamic loads.
