Abstract

Nanocomposites based on silica nanoparticles and high performance epoxy resins are investigated for their suitability as a new type of matrix for fibre-reinforced polymers (FRP) using injection technologies (LCM). The key focus is on the determination of the pro-cessing parameters at varying silica nanoparticle content. The homogeneous distribution of the nanoscaled silica in the epoxy matrix is proven by Photon Cross Correlation Spectroscopy (PCCS) and Scanning Electron Microscopy (SEM) analysis. Depending on the silica content of the composite, its stiffness, strength and toughness can be increased significantly compared with the neat resin. The mechanical performance is discussed by failure mechanisms based on the analysis of the fracture surface morphology. Moreover, resin shrinkage and the thermal expansion are significantly reduced both important for lowering internal stress in FRP. The injectability of the nanocomposite for the purpose of lamination using the LCM technology is nearly unaffected. Epoxy-silica nanocomposites are now proven to be a new high performance polymer matrix for FRP structures manu-factured by the low cost LCM techniques
