Abstrak/Abstract Weight plays a significant role in the automotive and aerospace fields due to the demandof lightweight material structures. A lighter body in weight (BIW) and in structure can reduce fuelconsumption, lessen emissions, and support the SDGs 9, 11, 12, and 13. Therefore, polyurethane (PU)foam is suitable for applications that require low weight. The characteristics of hybrid polyurethane-graphite micro were successfully evaluated in this study. Several tests have been used to characterizethese structures, such as, compression, hardness, density, surface evaluation, and FTIR analysis. Theresults showed that the expansion and shrinkage variations lead to different shapes at specific ratios.Compression tests show that the highest value occurred at 0.84 kN, with a 4:1 ratio found in pure PUfoam without any reinforcement. PU foam with 2% graphite filler showed the highest results at the4:1 ratio with a value of 0.45 kN. Furthermore, the highest hardness test result was 37.7 SHD. Densitytesting indicates that the highest value is obtained from specimens with a 4:1 ratio of 0.077 g/cm3.FTIR testing reveals that adding graphite as a filler alters the chemical bonds during the formation ofsolid PU foam. Surface observations show that adding graphite as a filler influences the variation inmaterial structure formation. All the evaluation has tended to conclude the present combination assuitable for lightweight structures applications
