Abstract

Purpose

Additive manufacturing is a recent technology used in the production of composite materials. The use of continuous fibres as reinforcement is necessary to achieve high mechanical performance. However, making these materials more environmentally friendly is still challenging. The purpose of this study was to investigate the feasibility of 3D printing a composite made of continuous regenerated cellulose fibres using a standard 3D printer generally used for printing polymers.

Design/methodology/approach

The production process was based on a pre-impregnated filament made from a tape containing continuous cellulose fibres and Pebax® matrix. 3D printed composite samples were fabricated using fused deposition modelling. The tape, filament and 3D printed composites were first analysed by means of modulated differential scanning calorimetry and micrography. Tensile tests were then performed, and the mechanical characteristics were determined at each step of the production process. Fracture surfaces were investigated by field-emission gun–scanning electron microscopy.

Findings

Results showed that the mechanical behaviour of the material was maintained throughout the production process, and the 3D printed biocomposites had a stiffness equivalent to that of traditionally manufactured continuous cellulose fibre composites. The obtained 3D printed composites showed an increase in strength value by a factor of 4 and in tensile modulus by a factor of 20 compared to those of unreinforced Pebax® polymer.

Originality/value

This paper demonstrates the feasibility of 3D printing composites based on continuous cellulose fibres, paving the way for new biocomposites made by additive manufacturing.

Abstract

Purpose

The purpose of this paper is to propose a reliable and valid integrative scale for online relationship quality based on both the relationship marketing and electronic commerce literature.

Design/methodology/approach

The scale was developed using the approach put forward by Churchill (1979). The scale development and validation process includes a qualitative exploratory phase, three pre-tests and a final study using an online questionnaire (476 members of a consumer panel).

Findings

The findings support a third-order integrative model of online relationship quality composed of three dimensions (trust, commitment and satisfaction). The final scale is composed of 21 items.

Research limitations/implications

The study shows a lack of discrimination between satisfaction and trust, which other studies have also found. As the scale is validated in only one sector, online banking, it should be tested and replicated in other contexts (e.g. insurance).

Practical implications

An instrument for assessing the quality of online relationships between banks and consumers is important for marketing professionals who want to determine their relational positioning and focus on those dimensions that promote long-term online relationships. The scale developed here can be used to assess customers’ perceptions of the quality of the relationship with an online financial institution, to segment those customers more effectively, and to improve targeting of marketing strategies and activities.

Originality/value

This study contributes to the enrichment of the body of theory and provides researchers with a tool for the further investigation of the quality of online relationships.
