Abstract:
Purpose- This study is part of the FP7 project ADVITAC and focuses 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.
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 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.
