Preliminary studies have been carried out using flexible laminates prepared from different types of PET films and UHMWPE (Dyneema) fabric using polyurethane based adhesive. Peel strength, Lap shear strength and helium leak rate of the samples were studied. The effect of plasma treatment of Dyneema fabric on the adhesion properties was analyzed. Discussions held with ISRO scientists provided focus to the subsequent studies. It was decided to modify the adhesive used with varied loadings of nanoclay to assess the barrier and mechanical properties of the resulting laminate
