Lava stone can be found around volcanoes and it has been widely used in human civilization. Composite which is an alloy of two or more materials who's each material still can be identified clearly. Composites with lava stone and matrix epoxy resin will have the properties of a combination of these materials. The mechanical properties of these composites can be improved by adding other materials which have a higher mechanical strength. In this study, carbon fibre was used as an additional reinforcing material. The lava stone powder used is the powder from sawing lava stone process. The lava stone powder was pulverized by a ball mill process for 4.5 hours. The matrix used was epoxy resin with a ratio of 2: 1 resin and hardener. The carbon fibre used is a short fibre with a length of 6 mm. The compressive test results on the lava stone-short carbon fibre composite showed the highest compressive strength was found in the composite with the addition of 1% carbon fibre (84.42 MPa) and epoxy 30%. © 2020 Institute of Physics Publishing.
