Objectif The demand to reduce weight of structural aircraft applications without sacrificing their strength and reliability is the key driving force in developing and employing advanced materials. The advantages demonstrated by fiber reinforced thermo set composites over conventional materials, such as high specific stiffness and strength, corrosion resistance, tailor ability and low thermal expansion enable to widely use these materials in the industry. Matrix toughening and fiber/matrix interface control can be distinguished amongst various methods aimed at improving the properties of these composites.Despite of wide use of nanoparticles for matrix toughening and fiber surface treatment, as well as intense researching the mechanisms responsible for the composite performance, there are fundamental questions to be clarified:1) Stronger adhesion between fiber and matrix is not always beneficial because while it improves stiffness and strength, it might decrease the fracture toughness.2) Effect of matrix modification might be reduced due to the presence of major reinforcement.3) Uniform dispersion of nanoparticles is critical to the structure of matrix. Due to a strong tendency of nanoparticles to agglomerate, nanoparticles homogeneous dispersion in polymers is considered a complicated process.4) Combining the modification of both fiber and matrix can give a synergetic effect resulting in tangible physical and mechanical property improvement of fiber reinforced composites.However, an optimal structure (i.e. a combination of fiber-surface treatment and matrix-modifier) is to be found for a given application. The work within the proposed project will involve theoretical and experimental investigations to address the above questions. The primary objective of the proposed research is to develop fiber reinforced thermo set composites of high specific strength and stiffness, and increased toughness for structural aircraft applications. Synergetic effect resulting in tangibly improved composites performance is supposed to be achieved through combining carbon and polyolefin fibers surface treatment, in order to obtain the optimal fiber/matrix adhesion strength and modifying epoxies with nanoparticles to improve toughness and thermal resistance.The proposed research will cover: detailed investigation of toughening phenomena caused by nanoparticles embedded in epoxy resins;development of technologies for surface treatment of carbon and polyolefin fibers;manufacturing of diamond, diamond-graphite and ceramics nanopowders of specified properties;development of a numerical model to simulate deformation and failure of fiber reinforced composites;development of a technology to incorporate continuous fibers and nanoparticles into thermo set resin;development of a interference-sensitive photo-detector including an interferometer with counter light beams.
