| Abstract | Dispersion of short carbon fibers in silicon carbide (SiC) matrix directly influences the homogeneity of mechanical properties of short carbon fiber reinforced silicon carbide composites, which is always a aporia in fabrication of short carbon fiber reinforced SiC composites, as well as the concentration for investigators in and abroad. in this paper, methyl cellulose (MC), carboxymethyl cellulose sodium(CMC) and hydroxyethyl cellulose (HEC) are respectively used as dispersant, worked carbon fibers are dispersed to unifilar by ultrasonic with addition of the dispersant. Then Ball milling the silicon carbide matrix and the dispersed fibers under the predefined formular to realize the homogeneous mix of the two substances. The paper mainly studies about effects of dispersants, ball milling time and concentration of short carbon fibers on dispersivity of carbon fibers among silicon carbide matrix, and the dispersion of fibers among the matrix was characterized by scanning electron microscope (SEM). The results show that the best dispersion appears when the content of fiber is 10vol% and with HEC as the dispersant, ball milling of 48h. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
