“…Commonly glass and carbon fiber reinforced polymer composites are the prime materials used for manufacturing of wind turbine rotor blades. However, there is necessity of more focused research on hybrid composite materials such as particulate filled fiber reinforced polymer composites . Polymer matrixes are usually modified by the addition of particulate fillers, such as silicon carbide , alumina , red mud , talc, and calcium carbonate , respectively.…”

This paper describes the mechanical, thermomechanical, and thermal behavior of unfilled E-glass fiber (10-50 wt%) reinforced polymer (GFRP) composites and granite powder filled (8-24 wt%) GFRP composite in different weight percentages, respectively. The void fraction of unfilled glass epoxy composite is decreased from 7.71% to 3.17% with the increase in fiber loading from 10 to 50 wt%. However, void fraction for granite powder filled GFRP composites show reverse in trend. The granite powder addition in glass-epoxy composites show significant improvement in hardness (37-47 Hv), impact strength (31.56-37.2 kJ/m 2 ), and stress intensity factor (by 14.29% for crack length of 5 mm) of the composites. The thermo-mechanical analyses also show strong correlation with the mechanical performance of the composites. The minimum difference of 0.17 GPa in storage and flexural moduli are observed for unfilled 20 wt% glass epoxy composite; whereas, maximum difference of 0.71 GPa is recorded for unfilled 50 wt% glass epoxy composite. Moreover, the numerical and experimentally measured thermal conductivity of unfilled and granite powder filled epoxy composites are within the lower and upper bound values. Hence, a successful attempt is presented for mechanical analysis of full scale model by finite element analysis. The results show that finite element analysis predicted reasonably actual stress value and tip deflection of wind turbine blade. POLYM. COMPOS.,

“…A wide group of composite structures is represented by fiber reinforced polymers [3,4], Fibred Metal Laminates or Sandwich Panels. They can be met in civil engineering (reinforcing windows or doors) [2], dentistry [10], orthopedics (implants) [7,10], the automotive industry (housings and panels) [1], the aircraft industry (skins of airplanes, wings) [13,17] or wind turbines (shovels) [9]. Their main advantage is a high strength to weight ratio.…”

This paper deals with the problem of the influence of the angular arrangement of laminas on the buckling force of rectangular composite plates. The article presents a general, simple analytical method of buckling load determination and finding the best arrangement in terms of the highest stiffness in the prebuckling state. Some special characteristic cases of arrangements in an eight layered GFRP laminate are assumed, and buckling force as a function of the arrangement is investigated by finding proper maxima. Results for some characteristic lay-ups are compared with FEM and results found in literature.

The small wind energy produces electric energy using power turbines below 100 kW. This technology allows the electrical supply in places isolated, generates energy of way distributed (distributed microgeneration) and permits to produce electricity in the points of consumption. The rotomoulding process is characterized to allow hollow plastics parts, with great surface quality, good homogeneity of thicknesses and suitable mechanical properties, all this with a great freedom of design and a wide variety of materials. The Department of Economy and Competitiveness from Government of Spain, inside the Subprogram INNPACTO 2012, resolved to grant the project of title Development of new blades made for rotational moulding for small wind generators (RotEos). The main purpose of this project is focused on getting a viable and cheaper process to manufacture the blades to small wind generators without reducing the efficiency of them, and trying to increase the competitiveness of these turbines. This research work presents the initial results obtained in the design of the blades, materials characterization and in the manufacturing process of these components.
