A new kind of superhybrid composite material,vinylon reinforced aluminium laminate (VIRALL),has been developed by laminating the vinylon/epoxy prepreg layers and the aluminium alloy sheets alternatively.The mechanical properties of VIRALL laminate have been tested and the results are dis- cussed in terms of laws of mixtures.About a 24% increase in tensile strength and a 36%decrease in tensile modulus to that of the corresponding aluminium were found,which kept good agreement with the laws of mixtures.Compared with the corresponding aluminium,VIRALL has lighter density and lower price.VIRALL is hoped to be a partial substitute for the civil aluminium alloy in the future.
