| Abstract | Cyanate ester (CE) is a polymer material regarded as a candidate for the insulation material of superconducting magnet for nuclear fusion reactor due to its high radiation stability. Therefore, the relationship between the mechanical strength of CE resin and its molecular structure was investigated. Glass fiber reinforced plastic (GFRP) with CE/epoxy resin compound was irradiated up to 10 MGy, and interlaminar shear strength (ILSS) test of the specimens was conducted at liquid nitrogen temperature (LNT). Additionally, IR spectroscopy and dynamic mechanical analysis (DMA) were also conducted to obtain information about changes in crosslink density. When the CE content of GFRPs is more than 40 wt%, the mechanical strength was hardly affected by irradiation up to 10 MGy because of rich triazine rings in their matrix. For the CE 20 wt% GFRP, decrease in the mechanical strength was observed over 5 MGy irradiation. This was partly because such samples contain few triazine rings in the polymer network structure and show low crosslink density. |

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.
