Description: The purpose of this project is to allow the spread out use of resin transfer moulding (RTM) processes in an industrial level. The structural components obtained by these processes show a high dispersion of their properties. Other processes can offer better quality but to a high price, economically as environmentally. The objective of this project is to control the RTM process substituting the conventional resin matrix by a nonmagnetic compound with magnetic-dependent viscosity that can be manipulated by a magnetic field. Resins with nanoparticles are being produced and analyzed, and the influence of these particles in the reactivity of the resins and their mechanical properties is being studied. The microstructure of this compound is analyzed using electronic microscopy and image processing in order to characterize the distribution of the nanoparticles in the structure of the resin. A platform to measure permeabilities was built to characterize reinforcements. This archetype allows fast permeability measurements and its effectiveness is being tested through benchmarking. With this project we expect to significantly reduce the variability of the production of composites and, thus, to reduce waste and the cost of the product.
