SMART COMPOSITE HYBRID STRUCTURES
Original language description
The original technology for structural composite beams was developed. It is suitable for components that require high bending stiffness, stability and damping. It allows combine ultra high modulus (UHM), high strength (HS) carbon fibres and other materials (metall, ruber, cork etc.) to manufacture structural elements. Also a novel type of 3D-cell hybrid composite structure was developed. The FE model of a periodic unit cell (PUC) consists of a core and a wrap. A matrix of homogenized elastic modules of PUC on the macro level was applied to build the final stiffness matrix of the whole hybrid composite structure containing a 3D sub-cell technology. The integrated fibre optic sensors with fibre Bragg grating (FBG) allowed a monitoring of deformation and debonding, for example of adhesive joints. A high-cycle fatigue properties of FBG sensors was investigated, as well as influence of embedded optical fiber on fatigue strength. Two types of carbon composite beams were tested. The experimental research showed that the tested FBG sensors have better fatigue durability than the conventional resistive foil strain gauges.
