“…• Kenaf fibers Kenaf fibers are considered among the most used natural fibers as reinforcement in composite structures [51][52][53][54]. Compared with other natural fibers [55] and based on many studies, kenaf fibers have always shown good mechanical properties, thermal stability and a strong fiber-matrix adhesion [56][57][58][59] [19], especially when submitted to chemical treatments [60].…”

The present work aims to assess the benefit of introducing simultaneously kenaf and carbon fibers in a composite wind turbine blade made initially of epoxy glass fiber. After an in-depth analysis of the optimal design of the blade using the Blade Element Momentum theory, an algorithm is generated in order to, firstly, establish the foundation of the blade geometry and secondly, to make a conservative static loading estimation representing a 50-years extreme gust. After performing the blade geometry on the 3D-modeler CATIA® V5, it was imported to PATRAN® software in order to create the mesh of the turbine blade. By modifying the way of stacking layups at each zone of the blade and by taking into account the plies properties, seven models were created. A further comparison was made between these models with a view of finding the best combination of fibers to satisfy the allowable thresholds. After several attempts of fibers combinations, it was finally revealed that the best way to combine the three fibers consists of replacing all unidirectional glass fibers of the blade skin with kenaf fibers and substituting those of the spar cap with carbon fibers while maintaining intact the remaining blade layups.

“…The results show that hybrid composites' mechanical properties have improved by increasing the hemp reinforcement layer. Dinesh et al [32] studied the tensile, toughness, and bending properties of hybrid composites reinforced with hemp/kenaf/glass fibers with different porcelain layers. It is observed that glass fiber/Kenaf and Hemp fiber combinations obtained the highest hardness compared to the other three ratios.…”

Natural fibre reinforced composites of any group are essential to satisfy the current demand and to keep the environment-friendly approach. In the present work, an attempt has been made to replace glass fibres partially by cotton fabric so as to reduce weight and cost of the resultant composite Here, cotton fabric 0.4 mm thick (125 GSM) and fibreglass woven roving 0.15 mm thick (180 GSM) were used with epoxy resin in different weight fractions to prepare hybrid composites. The composites were prepared using hand lay-up method. The Tensile strength, flexural strength, impact strength and hardness tests were performed as per ASTM standards and results are reported for each sample. The specimens were characterised using scanning electron microscope (SEM). The mechanical properties of composites with 80% glass fibre and 20% cotton fabric are found to be closer to glass/epoxy composites. Hence it is concluded that 20% glass fibres can be replaced by cotton fabric in the existing glass/epoxy products in which mechanical properties are important.
