Lava stone is a stone produced from a volcano. Mixing lava rock powder and resin will produce a new material, lava stone composite. The mechanical properties of lava rock composites differ from those of the constituent materials. These lava rock composites will be used as armor on military vehicles. The resin content used was 25, 30 and 35% while the lava stone powder was grinding with a ball mill for 3, 4.5 and 6 hours. Ball mill jar used have a capacity of 350 ml made of stainless steel. The ball used is made of ytria with diameters 10 and 5 mm the total of Ytria balls used are 10 mm were 78 pcs and 5 mm were 348 pcs. Composites that have the highest compression strength are composites with 35% resin and lava stone powder which is grinding at 6 hours. The most ductile composites is composites with 30% and lava stone powder which grinding at 4.5 hours The most suitable composites used to withstand shock loads are composites with 30% resin and lava stone powder grinding with a ball mill for 4.5 hours.
