Investigation of powder mixing methods on the energy absorption performance of graphene-reinforced cylindrical composite tubes

OpenAlex · English

In this study two methods were chosen for the production of composites: vacuum infusion and hand lay-up. The effect of varying the graphene addition method on the mechanical properties of the composite material was investigated. The first method involved adding graphene to the epoxy resin and infusing it into the fibre. The second method involved adding graphene dissolved in an acetone to the fibre. Quasi-static compression tests were applied to the samples, and the resulting energy absorption values (EA), specific energy absorption values (SEA), and peak forces (PF) were compared. The greatest EA was obtained with 200.42 joules with graphene-free epoxy resin matrix glass fibre produced by vacuum-infusion. The lowest EA was obtained with 132.32 joules with the sample produced by hand lay-up. In terms of PF values, the highest result was observed with 6.45 kN in the sample which graphene added in acetone solution.
