Abstract

Noise, harshness, and vibration (NHV) are problems encountered when driving a vehicle. This can cause serious problems for drivers if exposed to NHV for a long time. In order to avoid the NHV, vehicle are equipped with acoustic tile which functions to absorb vibration from the sound wave and reduce the noise caused by the vehicle’s engine. Polyurethane foam is commonly used as a sound absorption material because of its high sound absorption efficiency. The study aimed at investigating polystyrene (PS) and graphite (G) fillers with polyurethane matrix for improving acoustic property. The research started with optimization of composite that characterized using sound absorption intensity parameters at frequencies of 50 Hz-6000 Hz, and the optimum results obtained at matrix/filler 92.8%wt. The composite morphology is analyzed using SEM-EDX, optical microscopy, and the density. Mechanical test is conducted using Universal Testing Machine (UTM) and achieved the optimum compressive strength at 60G/40PS with 0.65 MPa. The absorption of acoustic waves property was tested in the frequency range 50 Hz-6300 Hz using an impedance tube and obtained the optimum composition at 0G/100PS.

Abstract

Aluminum material that is commonly used in life. This material is lightweight, corrosion resistant, tough and good working process. However, strength and hardness are lower than other metals such as steel. Processing needs to be done to get better aluminum mechanical properties. In this study, making a metal matrix composite in which aluminum 1100 as a substrate and 10 nm nano alumina (Al2O3) powder as a reinforcement. The process of making composites uses the method of accumulated roll bonding. The distribution of alumina powder on the aluminum matrix greatly influences the mechanical properties produced, namely its strength and hardness. The distribution process of nano alumina is carried out using screen printing, spray and ultrasonic spray methods. Besides the distribution method, the amount of alumina is also used as a research parameter. Improved optimum mechanical properties were obtained from the ultrasonic spray spray distribution method with the addition of 5 w/0 alumina.
