ISBN : 978-967-2454-09-0 Author : Mohd Azli Salim Laminated rubber-metal bearing from natural rubber also been well-known as a vibration isolator to block vibration energy. However, most of existing works on the bearing especially the mathematical models consider only the performance of the bearing due to the static force. Development of mathematical model for dynamic force and also its response is still lacking. Additionally, application of the existing rubber bearings only focuses on motion in the horizontal direction (sliding motion) intended to counter the energy coming from the earthquake. In this book, it is of interest to develop new techniques to perform the performance of the bearing subjected to axial excitation, and also to explore the potential of the vibration isolator for other applications, where dynamic loading can come from axial direction, such as cars passing by on the bridge or highway, or ground-borne vibration from railway lines. At the end, the model can be used for many applications which are mechanical, civil, building and many more.
Conductive ink is a special type of ink that allows an electric current to flow through the ink. The conductive ink-filled epoxy is also known as conductive composite because the ink itself is based on more than two ingredients such as filler, binder and hardener. As interconnect material, the conductive inks should feature good electrical, mechanical and thermal properties. Nonetheless, to-date, there are some issues with current conductive ink that available in the market namely printing quality, high electrical resistivity as well as inferior mechanical strength. Therefore, this book aims to produce highly functional conductive ink using two types of carbon-based conductive fillers with epoxy as a binder. More specifically, graphene nanoplatelets (GNP) and multiwalled carbon nanotube (MWCNT) were used to produce the hybrid conductive ink. It is very important to make sure the materials are contact with each other and therefore the movement of an electron will become easier.

This research applies a numerical study of topology optimization of laminate composite structures by using a Finite Element Method. In this methodology, the plies orientation is excluded from the optimization. The geometry-based optimization from frames of a MALE UAV fuselage structure is presented. The minimum strain energy with an optimization constraint of 20 percent of weight reduction is used in the objective function. Before the primary analysis, benchmark studies of topology optimization without considering orientations from previously published literature are performed. The convergence studies were taken to acquire the appropriate mesh size in the FEM technique, which utilized a four-noded shell element. The FE analysis and optimization results showed that the structural design of the newly frame composite fuselage MALE UAV meets the structural strength requirements specified in the airworthiness standard STANAG 4671.
This book focused on the mechanical properties of standard Malaysian natural rubber. On the other hand, it also represents the laminated rubber-metal spring (LR-MS) development for vibration isolator application. Besides, this book aims to implement the usage of Malaysian natural rubber up to four different mechanical approaches: tensile, compression, microscopic, and nanoindentation. This book, concludes the mechanical properties of different types of Malaysian natural rubber.
