With a view to developing low cost glass polymer multilayer composites (GPMLC) with high toughness, four layer laminar glass-epoxy-E glass fabric composites (GEF) were fabricated by a low pressure lamination technique. To promote weaker interfaces a thin sprayed layer of kerosene was introduced between the glass and the reinforcing layer in another group of composites (GEFK) fabricated in a similar manner. In both GEF and GEFK composites, a thin commercial cover slip gas disk (diameter 18 mm , thickness 0.3 mm) was used as the matrix layer. The load displacement plots of the GEF and GEFK composites exhibit a significant degree of non-linearity and stepped load-unload behaviour characteristic of fibre reinforced composites. The specific failure load (»200 N/mm) and the total work of failure per u.nit volume (»300 kJ.m-3) of the GEFK composite were found out to be the highest, thus indicating the development of a very high toughness material. These values were much higher than those of the brittle glass matrix, e.g., 20 N/mm and 20 kJ.m-3. The GEF composites showed the second best characteristics
