Abstract

Purpose

The manufacture of polymer composites with a lower environmental footprint requires incorporation of sustainably sourced components. In addition, the incorporation of novel components should not compromise the material properties. The purpose of this paper is to demonstrate the use of a synthetic amine functional toluidine acetaldehyde condensate (AFTAC) as a modifier for fiber-reinforced epoxy composites. One of the fiber components was sourced from agricultural byproducts, and glass fiber was used as the fiber component for comparison.

Design/methodology/approach

The AFTAC condensate was synthesized via an acid-catalyzed reaction between o-toluidine and acetaldehyde. To demonstrate its efficacy as a toughening agent for diglycidyl ether bisphenol A resin composites and for the comparison of reinforcing materials of interest, composites were fabricated using a natural fiber (mat stick) and a synthetic glass fiber as the reinforcing material. A matched metal die technique was used to fabricate the composites. Composites were prepared and their mechanical and thermal properties were evaluated.

Findings

The inclusion of AFTAC led to an improvement in the mechanical strengths of these composites without any significant deterioration of the thermal stability. It was also observed that the fracture strengths for mat stick fiber-reinforced composites were lower than that of glass fiber-reinforced composites.

Originality/value

To the best of the authors’ knowledge, the use of the AFTAC modifier as well as incorporation of mat stick fibers in epoxy composites has not been demonstrated previously.

Abstract

Purpose

Local organisations have been established on participatory approach whose central purpose is to establish development activities bringing about positive change as four pillars of developments: to establish decentralised robust local organisation for sustainable forest management to enhance livelihood of rural people, to meet the forest products basic needs of local people, targeted interventions for poverty alleviation and social mobilisation initiatives and biodiversity conservation climate change mitigation and adaptation.

Design/methodology/approach

Local organisational elites designed/conceptualised the concept, where it can be operated organisationally and in local organisational context that provides new ways and methods to develop conceptual framework (Table I), which sheds light on involvement of poor and underprivileged members in decision-making process and distribution of benefit on equity basis.

Findings

The findings will lead to a positive change through the organisational elite model through both reorganising organisations and restructuring of power with change in the society and reduce the impact of rational choices, vested interests of elites (leaders of local organisation) and political factors, which are otherwise playing a game or tragedy of commons.

Research limitations/implications

Because of the limited resources and time, the authors are unable to verify it on the other development line agencies such as drinking water scheme, livestock, health and cooperative.

Practical implications

It considerably appears that the impacts are very sound to conclude from the review of above models of elites that provide a very clear understanding and useful conceiving lens to formulate how participation occurs in the executive committee of the community forestry user groups (CFUG) and community-based organisations based on three key elements. First are the caste and the caste structure of the community. Second is the wealth status of the individual, and third is power created both from wealth and caste. This should be determined from the local organisational elite model (Table I) about the nature of interactions on the executive of the CFUGs and other vehicles of local community-based development organisations.

Social implications

Local organisations will provide an opportunity in reality to both elites and non-elites to considerably change, make aware and create a realistic situation to determine the dialectical opportunity to develop relationship, interaction and configuration between elite and non-elite members both outside and inside of the local organisations.

Originality/value

It has not been found in literatures yet such sort of concept developed in development field particularly in the development activities performed by participation of local users. Hence, it is certainly original conceptual framework.
