✦ Synopsis

In this Paper the problems of gas permeability and out-gassing are addressed, Epoxide resin based composite materials are studied in the form of cast resins with particulate fillers, fibre reinforced composites and low mass sandwich structures. The difficulty of manufacturing tubes and cylinders with continuous layers is also highlighted.

The permeability of a composite membrane consisting of a homogeneous layer and a porous layer has been derived theoretically by assuming that the permeation through the homogeneous layer obeys Fick's law and that permeation through the porous layer is free molecular flow.

When the insulation of a superconducting magnet is irradiated, the radiolytic gases will be produced in a condensed form and only mobilised when the magnet is warmed, following irradiation. The extent to which these gases will permeate through the resin or remain trapped within the polymer structure
