Abstract

Properties of composite materials with different matrices and disperse phases are greatly affected by phenomena occurring at the phase boundary with largest area. This is a boundary between matrix and fine filler. Numerous processes take place during preparation, homogenization and curing of the thermoset composites. While the achieved overall result is strengthening, the nature of mentioned processes is in many cases still unknown. In the present work we have carried out model study of transition layer which can be formed at the phase boundary during production of nanomodified epoxy composite. Raman spectroscopy is used for investigation of structure and composition. It is shown that silicone precursor is chemically inert to the matrix material. Application of such precursor leads to formation of low modulus transition layer between matrix and filler, thus promoting relaxation of internal stresses during curing process.
