The selection of adhesives and composite matrix resins for aircraft repairs
… water uptake, Tg dry and we t and diffusion coefficient. A computer programme written at Leicester Polytechnic was adapted to suit an IBM PC and this allowed water uptake within a lap joint to be related to time, diffusion coefficient and solubility coefficient. Later in the project attempts …

Gas transport properties in polycarbonate - Influence of the cooling rate, physical aging, and orientation
… experimental results suggest that the diffusion coefficient of small gas molecules in glassy polycarbonate is influenced by the local dynamics or mobility of the polymer chains rather than by the overall free volume content. Indeed, the diffusion coefficient of nitrogen for instance was reduced …

Pressure-Property Relationships in High-Performance Elastomers
… under pressure, and its relationship with gas solubility, crosslink density, loading and types of filler, and chemical structure under pressure, were investigated. It was observed that absorbed gas molecules have a significant impact on the change of Tg with pressure. We note that the Tg of the …
