The analysis makes three key findings and contributions.
First, the research suggests that sustainability is a substantial challenge for the industry due to the complexity of sustainability related factors and their linkages.
The microstructure properties of the foams were scanned using Micro Computer Tomography (Micro-CT) scanner, and the mean pore size was generated based on the micrographs obtained, while the acoustic properties of the foams were measured using a two-microphone impedance tube to determine its sound absorption coefficient efficiency.
This research provides new data on the physical, dynamic, microstructure and acoustical properties of natural rubber foam with different epoxidation levels.You do not need to contact us to get a copy of this thesis.Please use the 'Download' link(s) above to get a copy.
