Abstract:
Use of short fibers as reinforcing fillers in rubber composites is on an
increasing trend. They are popular due to the possibility of obtaining anisotropic
properties, ease of processing and economy. In the preparation of these composites
short fibers are incorporated on two roll mixing mills or in internal mixers. This is a
high energy intensive time consuming process. This calls for developing less energy
intensive and less time consuming processes for incorporation and distribution of
short fibers in the rubber matrix. One method for this is to incorporate fibers in the
latex stage. The present study is primarily to optimize the preparation of short
fiber- natural rubber composite by latex stage compounding and to evaluate the
resulting composites in terms of mechanical, dynamic mechanical and thermal
properties. A synthetic fiber (Nylon) and a natural fiber (Coir) are used to evaluate
the advantages of the processing through latex stage. To extract the full reinforcing
potential of the coir fibers the macro fibers are converted to micro fibers through
chemical and mechanical means.
The thesis is presented in 7 chapters
