Code = EMSHIP S3-10 (Semester S3)

Workload: 30h lectures, 60h project

Number of credits: 6

Objectives

The objective is to give relevant knowledge and capability to manufacture a composite part and to recycle naval composite structures

Contents

Advanced composite manufacturing processes (lecture + practice: 12h):

-          Study of two manufacturing processes, used for naval applications, for thermoset composites (RTM, infusion).

-          Practice: Laminate plate manufactured by RTM and Infusion process.

Visit of the shipbuilding company: BJ Technologies. The aim is to give an insight of a production line of sailing boats.

In-depht study of different aspects of the RTM process (lecture : 8h)

-          Capillary effects

-          Voids in composites : void formation and removal

-          Adaptation of the traditional RTM process to the thermoplastic composites

Composite recycling (lecture: 5h):

-          General overview of the context (legal requirements)

-          The different technologies used and under development, advantages and drawbacks (Solvolysis, Land filling, Pyrolysis, ...)

Design and manufacturing of a composite part (project: 60h)

-          From a given specification, manufacturing of a composite part for naval or wind turbine application
