Epoxy‐resin‐based composites filled with treated asbestos fibers were made. The asbestos, of chrysotile variety, was coated by impregnation in poly(hexamethylene adipamide) solution and the results of testing the tensile properties of the asbestos/polyamide/epoxy composite system are presented. The interest was focused on the influence of the asbestos content in the composite together with that of the polyamide content deposited on asbestos. No satisfactory reinforcing effect was found, especially when comparing with previous studies on coating the chrysotile by in situ interfacial polymerization. Nevertheless, a qualitative model was proposed to correlate the effect of the different phases contained in the composite with the experimental behavior encountered.
