By combining two MOF-based FBG sensors, we demonstrated three-dimensional strain-based monitoring of the curing of a fiber reinforced composite subcomponent manufactured by a resin transfer molding (RTM) technique. We also investigated the influence of the presence of the embedded fibers by embedding the MOF in composite coupons manufactured by liquid resin infusion (LRI) and performing a multitude of mechanical tests with these coupons and comparing the mechanical resistance to pristine coupons. It is also the first time that such a comparison has been carried out for this specific combination of optical fiber and composite material system. |
