Abstract

Purpose

The purpose of this paper is to focus on exploring an innovative combination of cutting‐edge technologies to be implemented within automated processes for composite parts manufacturing. The objective is the design of a production route for components with tailored fibre orientation and ply lay‐up, with improved damage tolerance thanks to through‐the‐thickness reinforcement and integrated health monitoring systems based on optical fibres technology. This study is part of the FP7 project ADVITAC.

Design/methodology/approach

The proposed technologies are described in detail and their compatibility and potential for integration are discussed.A set up for on‐line monitoring of infusion and curing processes of carbon/epoxy laminates preformed by dry fibre placement technology is proposed, and a preliminary study of their mechanical performance is presented. The possibility of reinforcing through‐the‐thickness preforms manufactured with dry slit tapes automatically laid‐up and consolidated by laser heating is investigated.

Findings

Improved knowledge was obtained of interaction/compatibility between the discussed technologies and scope for application.

Research limitations/implications

The paper reports the technical potential and practical feasibility of the proposed integrated production process. Limited quantitative evaluations on the materials performance are provided. The analysis of the technologies involved represents the early outcome of the ongoing ADVITAC project.

Practical implications

This study contributes to the identification of a new generation of composite architecture which allows production cost and weight savings while retaining the level of quality suitable for demanding structural applications, with particular relevance to the aerospace field.

Originality/value

This paper investigates for the first time the practical possibility of designing a single automated process involving dry fibre placement, tufting and optical fibre sensor monitoring for the production of complex composite components.

Abstract

It was only after considerable pressure had been brought to bear by the various health authorities of the country that the Government, in July, 1899, appointed a Departmental Committee to consider the subject of the use of preservatives and colouring matters in food, and it is now some months ago that the full report of the Committee was published, containing certain recommendations of the utmost importance for the consideration of the authorities. Up to the present time nothing further has been heard of the matter, and in answer to a question recently put to the President of the Local Government Board by the Mayor of Kensington, Sir SEYMOUR KING, as to whether the Board intends to take steps by the introduction of a Bill, or otherwise, for giving effect at an early date to the recommendations contained in the report of the Committee, the President stated that the report was “still under consideration,” and that he could make no statement at present as to the course which the Government would take.

Abstract

SOME amount of loss by enemy action has occurred in libraries since our last writing, but none of it has been on such a scale as we had to record earlier. This may be due to the more restricted raiding of the winter months, and, as we have so often remarked, is no assurance that more and great damage may not be endured—for it will be endured—when the boasted offensive takes place. It is gratifying to know that readers in heavily bombed areas continue faithful to libraries. Books have taken an even higher place lately, and if in these areas the circulation figures are smaller, it is because the populations are smaller. Individual readers use more books than ever.
