FIELD: development of light structural composite materials on the basis of fibrous fillers and polymeric binders, as well as of products resistant to impact and ballistic action on them, such as protective partitions, doors of the crew cabins, helmets, shields that may be used in the aircraft industry, machine-shipbuilding and other branches of industry.
SUBSTANCE: the offered prepreg includes an epoxy rubber or phenol-rubber binder (8 to 14 percent by mass) and an organic fibrous filler - cloth of aramidic thread (86 to 92 percent by mass). The cloth of aramidic thread may be preliminarily impregnated by an epoxy or phenol binder in amount of 4 to 6 percent by mass. A product is also offered that is resistant to an impact and ballistic action and made of the mentioned preparation.
EFFECT: produced a prepreg resistant to an impact and ballistic action, capable of long-term storage and suited to transportation.
