“…In terms of compressive load application, a very recent study were conducted on compressive loads on stiffened panel [11] and [12]. And in terms of application of compressive load in automotive structure, studies have been carried out as crush structure [13], and in the absorbent kinetic energy structure of a vehicle impact attenuator [14].…”

This article is an experimental study of honeycomb core carbon skin sandwich composite panel using American Standards for Testing Materials, ASTM Standards C365/C365M-11a for honeycomb structure flatwise compressive strength. The objective of this article is to describe the process of validation done in the specimens prepared in the research are, to have consistency in terms of the strength and other mechanical properties and to ensure the materials prepared in the lab and can be applied for aviation application (aircraft control surface) later. The samples were prepared in accordance with aviation industry standards using the aviation industry materials at the approved facility (Malaysian Airlines Composite workshop in Subang). The experiment was conducted using the Instron 8802 UTM by following the ASTM Standards at the Faculty of Mechanical Engineering, University Teknologi MARA. From the experiment in accordance with the test standard, the results of the experiment showed the consistency in terms of strength of the specimen. The ultimate strength was found at the average 5.88 kN.

Formula SAE is an international student design competition which is held in various parts of the world that challenges students to conceive, design, fabricate and test a single seater race car. Teams are evaluated based on business and technical presentations and dynamic performance of their cars. One of the important requirements of the Formula SAE car is its impact attenuator. It must be designed to absorb the specified impact energy. It is placed at the front of the car to protect the driver in the event of frontal collision. A new impact attenuator design which consists of aluminium circular tubes and L-sections arranged in a specified configuration is proposed. The attenuator is subjected to static and impact loads to determine its initial peak force (IPF), crush force efficiency (CFE) and specific energy absorption (SEA). Simulation result for static loading is validated by experiment. Minimum absorbed impact energy of 7350 J with peak acceleration of less than 40g and mean deceleration of 20g as specified in Formula SAE regulations is achieved. Impact simulation result also confirms that the impact attenuator is able to fulfil the requirements.

“…On the safety aspects, active protection (prevention) system such as anti-lock braking system (ABS), electronic brake system (EBS), traction control (TS), exhaust brake, retarder, are employed in most modern bus. However, lost of vehicle control which leads to crash can happen under extreme conditions where the law of physics cannot be defied [1]. Surveys done by Department of Road Transportation (JPJ) and Road Safety Research Institute of Malaysia (MIROS) have shown that substantial number of express buses are failed to comply with the United Nations Economic Commission for Europe (UN-ECE R66) regulations which is currently the highest standard set for bus structure.…”

Buses are the most popular and common passenger vehicle for long distance travel in Malaysia. Increased bus usage as a public transport prompts researchers to study safety aspects of the vehicles subjected to various crash incidents. The most damaging bus accident is rollover crash. The bus structures must have sufficient crashworthiness and strength in order to reduce and prevent injuries and fatalities during the rollover accident. Initially, this paper overviews the current status of rollover accidents and requirement of UN-ECE Regulation 66 which is aimed to improve the bus structure in withstanding the rollover crash. The current bus framework structure comprises galvanized square hollow sections (SHS) which are welded and bolted together. Abaqus was used to simulate responses of bus structure subjected to loadings as specified in UN-ECE Regulation 66. The results showed that the gap allowances of the residual space are complied with the UN-ECE R66 requirements. Further work to optimize the bus structure in terms of weight, structural strength and crashworthiness is proposed.
