Conceptual Design of Natural Composite Grating Platform
Abstract
There are several types of grating, such as platform, bridge decks and filters. In design process, there are several important terms that have to be prioritised; engineering design, strength to weight ratio, cost, maintainability, reparability etcetera. Advanced materials, such as composite materials offer great strength to weight ratio and high mechanical properties for grating fabrication. Furthermore the reparability and maintenance problems could be solved as it is anti corrosion and the long service life attribute of composite makes it a great design material for replacement of conventional steel or aluminium. Bio composites, such as bamboo and coir fiber yield advantage in terms of less cost and abundance availability compared to commercial unidirectional composite materials, such as glass fiber reinforced polymer (GFRP) and carbon fiber reinforced polymer (CFRP) which is considerably expensive yet possess higher mechanical properties. This papers presents a conceptual design of grating design utilizing bamboo composite as material. Pugh method has been chosen as design criteria selection matrix in finalizing the design of industrial grating for scaffolding (Pugh, 1991).
