    OVERVIEW

    The course provides the students with technological aspects about composite materials and relevant manufacturing methods. Simplified methods, aimed at designing multi-layered composites under given external loads, are also provided under the hypothesis of plane-stress condition.

    AIMS AND CONTENT

    LEARNING OUTCOMES

    The unit provides students with the technology and application concepts concerning composite material currently used in pleasure craft and yacht engineering sectors. Besides to shipyard manufacturing technologies, theoretical concepts to carry out scantling calculation through widely applied methods are given.

    AIMS AND LEARNING OUTCOMES

    The former part of the course (about 20 hours) is related to the decription of fber reinforced composite materials currently used in leisure boat industry, and typical manufacturing methods.

    The latter part of the course considers the mechanics of composites, namely the so called Classic Laminate Theory. About 25 theoretical lectures are followed by exercises aimed at describing scanlting methods for multi-layered fiber-reinforced composites.

    TEACHING METHODS

    Theorethical lectures for about 40 hours

    Practical exercises (whose results are to be carried by the student at the final exams) for about 12 hours

    EXAMS

    EXAM DESCRIPTION

    Oral exam on the whole course: a minimum of seven appointments if planned for each Academic Year

    the first question deals with mechanical aspects of composite materials.

    The second question deals with technological aspects of composite materials.

    Moreover, exercises presented during lectures are to be carried by students and discussed, as part of the final examination.

    ASSESSMENT METHODS

    60% of the grade is based on the mechanical part of the course, while the remaining 40% is based on the technological part.

    Solving the exercises proposed during lectures is mandatory.
