Abstract
Much research with recycled glass fiber reinforced composites has been targeted to extract glass fibers from their thermoset resin matrix or considered the shredded composites as the reinforcement system in a new second-generation composite. However, comparing the results of internal bonding of these recycled composites with the original thermoset composites indicates that there is a significantly weaker internal bonding between the recycled thermoset composites and matrix in the second-generation composites. Because of the lack of strong interfacial bonding, there is a possibility to improve the bonding between the recycled thermoset composites and matrix. Among inorganic oxide fillers, silica particles have received much attention due to their well-defined ordered structure, high surface area, cost-effective production, and ease of surface modification. The main issue with using silica is agglomeration and miscibility of silica particles, so we consider an innovative structure of silica, called networked silica to overcome these problems. Networked silica (NS) is a 3D structure of silica that is created by interconnecting silica particles with bridge chains of aliphatic, aromatic, poly imine, peptide, and polyether groups. In this research, we create a 3D structure of silica by interconnecting silica particles with pMDI and consider this NS as the surface modifier of glass fiber polymer and cementitious composites.
