Fabrication, characterization and modelling of laminated composites based on woven jute fibres reinforced epoxy resin

摘要

The aim of this work is the manufacturing and study of mechanical properties of laminated composite based on natural jute fibres and epoxy resin. The laminated have been prepared by using a compression system according to two jute fibre direction (0° and 45°), and two sample cutting directions (0° and 45°). The different used directions permit to reduce the anisotropic character of manufactured composites. The experimental results show that the mechanical properties increase with increasing of number of layers. The maximal Young's modulus of laminated with 1, 3, 5 and 7 layers were found respectively at 5264, 5902, 6400 and 5562 MPa in case of 0° fibre direction and 0° cutting direction. Moreover, the predicted modulus (Young's modulus, shear modulus and Poisson coefficient) in each fibre direction were found near to the experimental ones. The difference resides probably in the error in the considered assumptions about the perfect bonding between the fibres and matrix. It was also observed that the use of different staking orientation reduce the anisotropic character of obtained composites.
