10. A method of making the composite ballistic panel of any one of claims 1-9, comprising the steps of:
s1: according to the number of ceramic plates (20) required to be arranged on the mounting plate (10), through holes or screw holes twice as many as the ceramic plates (20) are formed in corresponding positions, and meanwhile, holes are formed in the elastic buffer piece (40);
s2: penetrating a fastening bolt (50) through an elastic buffer piece (40), screwing a nut, welding and fixing the nut and the elastic buffer piece (40), and screwing out the fastening bolt (50);
s3: inserting two elastic buffer pieces (40) into two slots (21) of a ceramic plate (20), and then installing the ceramic plate (20) along an installation plate (10) through fastening bolts (50) and nuts in sequence from bottom to top;
s4: then sequentially pasting the splash-proof plate (30) on the surface of the ceramic plate (20);
the preparation method of the splash guard (30) comprises the following steps: firstly, a shell of the splash guard (30) is manufactured and molded by two parts by using a mold; then laying a paraffin layer (32) and a polystyrene-polydimethylsiloxane cross-linked copolymer layer (31) in a portion; then the other part is fixed by hot sticking to cover the hot melting layer; then, the adhesive layer (33) is adhered to the inner side of the splash guard (30).
