| Abstract | To simulate the results of surface treatments, commonly encountered functional groups were introduced onto the surface of the carbon fibre model. The carbon fibre model used in this study is based on the single layer diagonal graphitic plane, comprising 52 six-membered rings, in a 4×13 configuration, and of 150 carbon atoms. Surface treatment was represented by the introduction of functional groups (–R): each time, a C–C bond was broken along the edge of the plane, and a pair of –R groups was added to the graphitic plane. The total number of functional groups (n) was six. The effect of these functional groups on the non-covalent bonding interactions at the composite interface between carbon fibre and epoxy resin was investigated using a previously established BLENDS method. The compatibility of the resin and fibre in this model, indicated by the interaction parameter χ(T ), was dependent upon two factors: steric bulk and electrostatic interactions. The halogen substituents show a decrease in χ(T ), as one descends the group. Maximum interaction tends to be a function of steric bulk and polarizability in this group. The alkyl (CnH2n+1) and phenyl substituents also show a decreasing trend inχ(T ) with increasing size, although the interaction parameter with methyl is anomalously low in all cases. |

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.
