The utilisation of composite materials in aircraft structures has constantly been in an uptrend in the aerospace industry. However, composites do require protection to preserve their strength and prevent the components from experiencing external reaction such as corrosion. This can be done by applying a layer of sealant on the machined surfaces of the composites. The study focused to achieve the desired base-accelerator proportion required to form the sealant. This paper will discuss the viable parameters expressed in the Hagen-Poiseuille equation, the methodology practised, and the potential factors affecting viscous flows. The latter section of this study proposes the desirable parameters which shall be set as variables for dispensing systems which involve the handling of viscous fluid flows. The experimental data revealed and validated that varying the tube length yields the highest accuracy and consistency, with a minimum error of 0.403% compared to the desired base-to-accelerator ratio, and the lowest standard deviation of only 0.040.
