METHOD TO INCREASE CELLULAR FILLER STRENGTH

摘要

FIELD: machine building. ^ SUBSTANCE: invention relates to production of deformable obstacles used in testing the vehicle safety in vehicle collision conditions. The method of increasing the strength of cellular filler consists in spraying a 20 to 40% solution of epoxy resin in acetone on the walls of cellular filler cells made of aluminium foil, the said solution being preheated to the temperature above the epoxy resin jellification. In spraying, the cellular filler cells axis is arranged at an angle to the sprayed solution jet. Now, solidification occurs. ^ EFFECT: higher strength of cellular filler, higher stability of the filler properties in compression. ^ 1 tbl
