Current developments in sports have made government regulations increasingly stringent regarding the consumption of Eva foam in archery sports, this requires archery buttress manufacturers to change their minds so that the need for the Eva foam they make can meet these regulations. One effort that can be taken to save on eva foam consumption is the use of environmentally friendly archery buttress material. At this time, composites are predicted to be materials that can replace the role of Eva foam as a supporting material, but on the other hand, composites have a weakness in their resistance to low shock loads, although there are several archery buttresses that use natural materials, this of course requires a level of thickness. which is thin and effective for use in the field as well as low production costs because strong and high-quality natural fibers require quite complicated processes so they are expensive. Therefore, latex matrix composites reinforced with hemp fiber waste are used to correct these weaknesses at an economical cost. In this study, the fiber used was a latex matrix composite reinforced with hemp fiber waste with a fiber volume fraction of 30%, 40% and 50% with hemp fiber waste lengths of 3 cm, 5 cm and 7 cm which were tested for tensile and bending strength. Based on the research results, it can be concluded that (1) Volume fraction influences the tensile and bending strength of latex matrix composites reinforced with hemp fiber waste, with the greatest results lying in the 50% variation in volume fraction which has a tensile and bending strength of 446.94 MPa and 26. 23 MPa (2) The length of hemp fiber waste has an effect on the tensile and bending strength of latex matrix composites reinforced with hemp fiber waste, with the greatest results being the hemp fiber length of 3 cm which produces tensile and bending strength values of 448.38 MPa and 29. 42 MPa. © 2025 Author(s).
