A Study on Comparison of Temperature Distribution between Aluminum and GFRP Mold under Carbon Spar-Cap Manufacturing Process

In this study, temperature distribution as a function of the spar-cap thickness was numerically analyzed using 20 kW wind carbon blade model. “Realizable k-ε”, which adopted turbulence model for heat transfer analysis, effective in convection and diffusion calculations. SC/TETRA, commercial thermal fluid analysis software, used to calculate flow from panel outside boundary simulation order derive equation between mold surface top spar-cap, interval 10 °C, range 60 °C 110 °C. As result, insufficient cure Carbon Fiber Reinforced Plastic (CFRP) because did not reach spar-cap. To resolve problem loss, derived by dividing conditions laminates. The unevenness curing process reduced improved condition. addition, cases where GFRP aluminum were applied upper compared same method. An improvement reduce non-uniformity studied solve non-curing issue under manufacturing process.
