Title: CHARACTERIZATION OF FIBER REINFORCED POLYMER (FRP) COMPOSITE MATERIALS APPLICABLE ON STRUCTURAL MODELLING OF WIND TURBINE BLADE AT ELEVATED TEMPERATURE  

 

Abstract: Carbon fiber, glass fiber and hybrids of the two composite materials have been widely used on structural modelling of wind turbine blades. The static and dynamic mechanical properties of FRP composite material needs investigation before incorporation of these material for modelling wind turbine blade structures specifically for tropical wind farms. In this study, we presents an experimental investigation using short beam shear (SBS) and dynamic mechanical analysis (DMA) tests to determine the inter-laminar shear failure strength (ILSS) and dynamic mechanical behaviour like storage and loss modulus properties of inexpensive glass fiber reinforced polymer (GFRP) composite material, expansive carbon fiber reinforced polymer (CFRP) composite laminates and hybrids of the two materials at testing temperatures ranging from 0 25 Cto 0 55 . C These composite laminates  were fabricated using hand lamination process and testing occurred as per ASTM: D 2344 and ASTM: D5023 standards. Based on testing result obtained from SBS and DMA, the inter-laminar shear failure strength (ILSS), storage and loss modulus of all composite laminates reduced as the temperature rises. Considering experimental data, hybrid composite laminate has nearly similar inter-laminar shear failure strength compared to expensive carbon/epoxy laminate and has higher damping behaviour. It is economical and a better candidate for modelling the structures of the wind turbine blade applicable on tropical wind farms, especially vibration and noise is critical.
