“…The main material that is often found is carbon fiber. The characteristics possessed by this carbon fiber are that it has good strength and rigidity and is able to increase the electrical conductivity properties [1]. Not only that, but its light weight is also one of the advantages of carbon fiber.…”

Abaca is a kind of banana that grows in Indonesia. Abaca banana product utilized in this research is a fiber that obtained from the midrib of the stem. Henceforth, abaca fiber is processed to be the form of membranes. The purpose of the study is to determine the physical, mechanical, and acoustic properties of abaca fiber composite materials as fillers and polyvinyl acetate (PVA) as a matrix. The ratio of composite materials of abaca fiber and PVA is 1:10. The variations used in producing membranes are the addition of carbon powders by 0, 2, 4, 6 and 8%. The characteristics carried out include testing of density, morphology, tensile strength, and sound absorption coefficient. The results reveal that the highest density is obtained from the sample of 0% carbon, i.e., 1.026 gr/cm 3 . Furthermore, the mechanical properties testing shows the highest yield stress value in samples with 4% carbon of 476.8 MPa and the highest Young modulus in samples with 8% carbon is 7905.1 MPa. Therefore, the addition of carbon could improve the mechanical properties of composites materials. Based on the measurement of sound absorption coefficient using an impedance tube with 1 microphone, the highest value can be attained from the sample of 4% carbon, namely 0.211 which shows the sample is more reflective. The material is reflective because the amount of abaca fiber used is less than PVA. The diameter of pores formed between the fiber and PVA are very small which could cause the absorption coefficient value to be lower. Therefore, further research will focus on the addition of abaca fiber content in composite materials. The positive point in this study is that the addition of carbon with 4 and 8% provides optimal mechanical ability.

In this study, process parameters and mechanical properties of the multi-scale composite were investigated experimentally and predictably. Multi-scale material includes boron carbide particles and multi walled carbon nanotubes (MWCNTs) in the epoxy-based matrix. Both reinforcements were reinforced into the matrix with various rates simultaneously. Average three tensile strength and hardness values were determined. The tensile strength and hardness were enhanced thanks to high rate of B4C usage up to 54.09% and 2.54%, respectively. The microstructure of the hybrid composite was investigated by Scanning Electron Microscopy. Also, Fourier Transform Infrared Spectroscopy was used to interpret spectral bands. The experimental data were analyzed using optimization method. Optimal process parameters for tensile strength and interfacial properties were determined. The Analysis of Variance (ANOVA) was used to obtain most significant factor and optimum levels of parameters. Finally, it was observed that B4C ratio is the most dominant factor affecting the mechanical and thermal properties.
