Abstract

This research focuses on tensile and damping properties of Graphene Nanoplatelets (GNPs)/Carbon blacks (CBs) filled Chloroprene (CR) nanocomposite. The research is an industrial cooperated project in which it is supported by Saiko Rubber (M) Sdn Bhd, a rubber compounding manufacture industry located at Senawang, Negeri Sembilan. The study aims to determine the tensile and damping properties of the GNPs/CBs filled CR nanocomposite as well as to analyze the morphological of the GNPs/CBs filled CR nanocomposite to further clarify the tensile and damping properties of the nanocomposites. The incorporation of the GNPs/CBs hybrid system is to enhance the tensile and damping properties of the CR nanocomposites on the existing CR nanocomposite formulation. In the beginning of the research, CR compound was produced by using Intensive Mixer at temperature 95°C and motor speed at 800rpm. The processing parameter was based on the suggestion from industry. Then, the compound was filled with nanofillers (GNPs/CBs). The CR nanocomposites were then vulcanized using hot press at 160°C after being tested for cure characteristics using Monsanto moving die rheometer (MDR 2000) accordance to ASTM D 2084, tensile properties was conducted by using universal testing machine (U-CAN) accordance to JIS K 6251 and damping properties by using accelerometer (Free Vibration Test). Morphological characteristics were also studied. Next, the findings were further supported by morphological and thermal evaluation by using Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) analysis and Differential Scanning Calorimetry (DSC) respectively. The introduction of GNPs into the CR matrix showed good compatibility with respect to the observed enhancement on the tensile and damping properties. XRD and FTIR pattern had provided adequate explanation as well on the dispersion of GNPs in the CR matrix. In overall, the introduction of GNPs into the CR matrix is able to provide improved mechanical and damping properties which is beneficial for the engine mounting application.
