“…Namun, terjadi failure pada salah satu sudu setelah beberapa ratus jam beroperasi [6]. Secara keseluruhan, sudu turbin memiliki proporsi terbesar dalam fatigue failure, yaitu sebesar 50% dibandingkan komponen lainnya [7]. Hal ini menunjukkan pentingnya dilakukan studi lanjut mengenai sudu turbin angin.…”

Print) B70 Abstrak-Dalam pembuatan sudu turbin angin harus diperhatikan material yang digunakan. Sudu turbin angin harus memiliki kekuatan spesifik yang tinggi (strength to weight ratio) dengan berat yang ringan. Oleh karena itu, pada penelitian ini akan dipelajari kinerja spar dari sudu turbin angin yang terbuat dari material komposit carbon reinforced polymer dan glass fiber reinforced polymer. Struktur spar pada sudu turbin angin memiliki geometri cantilever I beam. Dimensi spar disesuaikan dengan dimensi pada turbin angin riset AVATAR (Advanced iv Aerodynamic Tools of large Rotors) dan referensi INNWIND.EU dengan lebar pada flange dan web dibuat menjadi konstan. Penelitian dilakukan dengan pendekatan numerik finite element analysis menggunakan aplikasi ABAQUS CAE 2017. Sebelumnya akan dilakukan validasi model simulasi dengan membandingkan hasil defleksi studi terdahulu dengan penelitian ini. Hasil dari validasi menghasilkan perbedaan defleksi sebesar 0.1%. Hal ini menandakan pemodelan yang digunakan sudah sesuai. Selanjutnya, dipelajari kinerja defleksi dan tegangan pada spar yang terbuat dari 3 material berbeda yaitu S-glass 913/epoxy, TC35/epoxy, dan M55/epoxy dengan distribusi serat merata dan unidirectional. Hasil penelitian menunjukkan nilai defleksi dipengaruhi oleh modulus elastisitas E1 yang dapat menahan deformasi elastis. Selain itu, didapatkan daerah yang memiliki tegangan paling tinggi pada spar caps terletak di bagian root yang menjadi penopang gaya pembebanan. Sedangkan pada shear web, tegangan maksimum terletak pada bagian atas dan bawah yang mengalami kontak langsung dengan spar caps. Ketiga daerah ini harus diperhatikan lebih lanjut dikarenakan daerah dengan tegangan maksimum memiliki kemungkinan terjadinya failure pada sudu turbin angin.

“…The advantage of low weight (density) blade is that the wind blade easily overcomes friction and begins to rotate within a low cut in wind speed. A wind turbine design that reduces the cut-in wind speed through a proper design of the blades will be characterized by a significant performance improvement [20]. Thus, one of the ways to reduce the cut-in speed is reducing the weight of the turbine blade.…”

“…Thus, material variation affects the vibration mode of the blade. During the design of a wind turbine blade, the 1 st flap-wise, 2 nd flapwise, 1 st edge-wise and the 1 st torsional natural frequencies were determined as a minimum [20]. It was noted that only the frequency range between 0.5 Hz and 30 Hz [21] is of relevance to the considered wind turbine blades.…”

The availability of some form of energy is essential for the human survival and social development. However, the way energy has been generated within the last century has brought forward the quest for the generation of energy without polluting the environment, which is nowadays considered to be the greatest global challenge. The materials used for wind turbine blades can be classified under this challenge of polluting the environment. One of the materials expected to reduce this problem is natural fiber reinforced composite (FRC). Thus, the focus of this paper was to evaluate the potential of different natural FRC materials for small wind turbine blade application. Eleven different natural fibers reinforced composite in epoxy resin were studied. A modified Halphin-Tsai semi-empirical model was used to compute the physical properties of the composites, since it has a good agreement with the experimental results. Stress, deformation, and weight of wind turbine blade under different loadings were analyzed aimed to search for a fiber type that may extend the life span of the blade. Finally, flap wise and edge wise, the longitudinal and torsional natural frequencies were computed numerically by using the finite element method in the Qblade software (QFEM) under different mode types and the effects were analysed. Upon comparing the results with a common composite material for wind turbine blade (E-glass/epoxy), it was observed that the selected natural fiber composites have equivalent and better mechanical performance. The environmental friendliness of natural fibers, i.e. biodegradability, constitutes their advantage as materials of wind turbine blades.

“…Wind is an alternative, renewable and clean energy source with low environmental impact, permanently and globally available [ 1 ]. To capture and convert wind energy, aerogenerator turbine blades develop an imbalance between lift and drag forces [ 2 ]. The wind and gravity cyclic loading histories that exist at the various locations in the blades suggest that it could be advantageous to use different materials for different parts of the blade in order to avoid failures [ 3 , 4 , 5 ].…”

Damage generated due to low velocity impact in composite plates was evaluated focusing on the design and structural integrity of wind turbine blades. Impact properties of composite plates manufactured with thermoplastic and thermoset resins for different energy levels were measured and compared. Specimens were fabricated using VARTM (vacuum assisted resin transfer molding), using both matrix systems in conjunction with carbon, glass and carbon/glass hybrid fibers in the NCF (non-crimp fabric) architecture. Resin systems used were ELIUM 188O (thermoplastic) from Arkema Co., Ltd. and a standard epoxy reference, EPR-L20 from Hexion Co., Ltd. (thermoset). Auxiliary numerical finite element analyses were performed to better understand the tests physics. These models were then compared with the experimental results to verify their predictive capacity, given the intrinsic limitations due to their simplicity. Based in the presented results, it is possible to observe that ELIUM is capable to replace a conventional thermoset matrix. The thermoplastic panels presented similar results compared to its thermoset counterparts, with even a trend of less impact damage. Additionally, for both thermoplastic and thermoset resin systems, glass layups showed the lowest levels of damage while carbon panels presented the highest damage levels. Hybrid laminates can be applied as a compromise solution.
