In　this　study,　epoxy　resin　(EP)　composites　were　prepared　by　using　molybdenum　disulfide　(MoS2)　and　helical　carbon　nanotubes　(H-CNTs)　as　the　antifriction　and　reinforcing　phases,　respectively.　The　effects　of　MoS2　and　H-CNTs　on　the　friction　coefficient,　wear　amount,　hardness,　and　elastic　modulus　of　the　composites　were　investigated.　The　tribological　properties　of　the　composites　were　tested　using　the　UMT-3MT　friction　testing　machine,　non-contact　three-dimensional　surface　profilometers,　and　nanoindenters.　The　analytical　results　showed　that　the　friction　coefficient　of　the　composites　initially　decreased　and　then　increased　with　the　increase　in　the　MoS2　content.　The　friction　coefficient　was　the　smallest　when　the　MoS2　content　in　the　EP　was　6%,　and　the　wear　amount　increased　gradually.　With　the　increasing　content　of　H-CNTs,　the　friction　coefficient　of　the　composite　material　did　not　change　significantly,　although　the　wear　amount　decreased　gradually.　When　the　MoS2　and　H-CNTs　contents　were　6%　and　4%,　respectively,　the　composite　exhibited　the　minimum　friction　coefficient　and　a　small　amount　of　wear.　Moreover,　the　addition　of　H-CNTs　significantly　enhanced　the　hardness　and　elastic　modulus　of　the　composites,　which　could　be　applied　as　materials　in　high-temperature　and　high-pressure　environments　where　lubricants　and　greases　do　not　work.
