| 6 | Effect of Recycling Cycles on the Mechanical and Damping Properties of Short Alfa Fibre Reinforced Polypropylene Composite显示文摘This paper aims at studying the effect of recycling on the static and dynamic properties of short alfa fibre reinforced polypropylene.For this purpose,alfa fibres reinforced composites were elaborated by an injection moulding process and were subjected to different mechanical recycling cycles.Then,non-recycled and recycled materials were subjected to static tests and Dynamic Mechanical Analysis(DMA)to evaluate the effect of recycling on their behaviour.Besides,the effects of alkali and salt water treatments on the static and dynamic properties of the alfa composite were also investigated.The obtained results show that tensile and flexural properties of alfa fibres reinforced composites decrease during recycling cycles.Moreover,the recycling induces a drop in the storage modulus and enhances the loss factor of these composites.The composites with alfa fibre especially the alkali treated composite show the same resistance to recycling as composites with hemp fibres.Further,SEM observations indicate a decrease in the fibres dimension with the recycling cycles,especially for alfa fibres,which can explain the decrease in the properties of the alfa composite during recycling operations. | Fatima Ezzahra El Abbassi Mustapha Assarar Rezak Ayad Hamid Sabhi Stephane Buet Nouzha Lamdouar | 2019 | Journal of Renewable Materials2019，7，3： | 0 |
| 7 | Numerical Modelling of the Transient Hygroscopic Behavior of Flax-Epoxy Composite显示文摘This contribution deals with the development of a three-node triangular plane finite element to analyze the transient hygroscopic behavior of 2/2 twill flax fabric-reinforced epoxy composite.Several plates of this material were fabricated using the vacuum infusion process and composite specimens were then cut and aged in tap water at room temperature until saturation.To simplify,a plane modelling of water diffusion in the aged specimens is adopted and Fick’s model is used to describe the water diffusion kinetics.To highlight the heterogeneity of the flax-epoxy samples,the twill flax fabrics waviness is modelled with a sinusoidal undulation.In particular,we show that the proposed finite element formulation allows estimating the flax fiber radial diffusion coefficient by an inverse approach. | Wajdi Zouari Mustapha Assarar Abderrazak Chilali Rezak Ayad Hocine Kebir | 2019 | Journal of Renewable Materials2019，7，9： | 0 |
| 8 | Effect of Stacking Sequences on the Mechanical and Damping Properties of Flax Glass Fiber Hybrid显示文摘The aim of this study is to show the interest of the mechanical and dynamical properties of glass-flax hybrid composites.Therefore,various staking sequences of glass-flax hybrid composites were manufactured and tested in free vibrations.The damping coefficients were identified by fitting the experimental responses of free-free bending vibrations.The obtained results show that the staking sequences and the position of flax fiber layers in the hybrid composites changed the properties,so a classification of different stacking sequences was established.In fact,the hybrid laminate made of two glass external layers placed on both sides of four flax layers is very interesting in term of its mechanical and damping properties.Indeed,it showed better specific bending modulus and loss factor than glass composites with proportions of 31 and 39%,respectively.A study of a structure of this composite has been made to validate the obtained results. | Khouloud Cheour Mustapha Assarar Daniel Scida Rezak Ayad Xiaolu Gong | 2019 | Journal of Renewable Materials2019，7，9： | 0 |
