We made a structure property correlation (SPC) by altering systematically the chemistry of a cross-linked epoxy resin and examining the material behaviour and failure mechanisms under the external influence of moisture, temperature and stress. The epoxy resin (aromatic epoxy: 1,3-Bis-(2,3-epoxypropyl)-benzene and amine hardener: 1,2-Diaminoethan ) was examined under different loading conditions (65degC/75rh,...
The authors first investigate a polymeric composite material ( epoxy resin with silicone nanoparticles) and determine its mechanical properties (coefficient of thermal expansion-CTE and Young's Modulus-E) by a combined experimental and simulative (homogenisation) approach. The size distribution and the volume fraction percentage of the nanoparticles were determined as well as the variation of the...
The present work deals with the self-diffusion coefficient of water molecules in amorphous polymeric materials (aromatic epoxy: 1,3-Bis-(2,3-epoxypropyl)-benzene and amine hardener: 1,2-Diaminoethan). Both experiments and molecular dynamics (MD) simulations examine the temperature range of 300-400K, where diffusion coefficients are calculated under NVT-thermodynamic boundary conditions by using a...
