The usage of hybrid natural composites has surged in almost all fields of engineering due to their advantage of possessing high strength to weight ratio and biodegradability. This paper deals with the fabrication and investigation of mechanical and thermal properties of banana-kenaf glass fiber reinforced epoxy composite which is relatively a newer hybrid composite. In this study, the composite is fabricated by a hand layup process with different fiber orientations and also with different volume fractions. The composites are prepared with five different proportions of banana-kenaf fibers. Various mechanical and thermal tests are conducted and the result shows that the hybrid composite in which fibers are arranged at 45 0 inclination has better properties than the others. Also, failure morphology analysis is done using a Scanning Electron Microscope (SEM) through which the internal structures of the tested specimen are analysed.
Engineering materials are classified into many varies and composites are those which are finding their role in all modern day engineering applications. Composites are those materials made out of two basic components; a polymer resin and fibers. It combines the physical enactment and high mechanical of the fibers and the look, bonding and properties of polymers. For these uses the natural fibers could be considered rather than synthetic types. Due to their high strength and modulus, reinforced polymer composites have started to play a key role in a wide range of applications. Due to high cost involved in production, the usage of synthetic fibers is restricted whereas natural fibers are cheap in cost, strong, less weight and largely available.
Now-a-days automated and interconnected process as in Distributed Control System requires a very reliable communication. The serial communication protocol called CAN (Controller Area Network) is taken into account and is made more reliable by introducing additional fault confinement mechanisms. Since actual CAN protocol is BUS topology based in which multiple components (direct electrical connection between the nodes) are present, its use in safety critical application is not recommended. So active STAR topology based CAN protocol is proposed, which needs the design of respective HUB that could enforce confinement of faulty nodes thus avoiding any severe failure of communication. In future the HUB with its fault tolerant mechanism is to be implemented in FPGA and further can be realized as an ASIC.
Composites are materials made out of a polymer resin reinforced by fibers, merging the high mechanical and physical enactment of the fibers and the appearance, bonding and physical properties of polymers. For these uses the exchange of industrial fibers with natural fibers could be considered. Many natural fibers traditionally employed in weaving, sacking and ropes; present various abilities to be used as reinforcement elements in composites. Reinforced polymer composites have started to play a pivotal role in a wide range of applications due to their high strength and modulus. The fibers used may be synthetic or natural in reinforced composites. Due to high production cost, the usage of synthetic fibers is confined whereas natural fibers apart from being cheap in cost, it is also strong, less weight and amply available.
