Influence of reinforcement effect on mechanical properties of banana bio fiber polyester has been investigated. Three different type of weaving patterns such as plain, basket and twill banana fabric were used to analyze the mechanical properties of composites. Results revealed that composite with basket weaving style enhances the properties of composite material compared to other two patterns. ...
Polyester-fiber-reinforced cement-stabilized concrete is widely adopted to prevent the shrinkage cracking in pavement engineering. However, effects of fiber length and content on dry temperature are not clear. The relationship between resistance strength also discussed scantily. Hence, five types polyester (1 cm, 3 5 7 9 cm) six (0.1‰, 0.3‰, 0.5‰, 0.7‰, 0.9‰, 1.1‰) were selected prepare fiber-r...
in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...
Natural fibers are receiving considerable attention as substitutes for synthetic fiber reinforcements such as glass in polymer due to their low density, low cost, acceptable specific strength, reduced tool wear and respiratory irritation and renewable resources. The fibers are not uniformly distributed in the randomly oriented fiber reinforced hybrid composites due to manual lay-up and fibers a...
Aiming at demonstrating the potential of unidirectional natural fiber-reinforced thermoplastic composites in structural applications, textile flax yarn/thermoplastic polyester composites with variable fiber volume fractions have been manufactured by a filament-winding process followed by a vacuum-assisted compression molding process. The microstructure of the composites shows that the flax fibe...
