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.
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.
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.
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
1-Introduction to the course
2-Description of the glass fiber and polyester resin and relative main features
3-Description of epoxy resin: features and critical issues
4-Manufacturing methods of composite materials in leisure boat industry: traditional hand lay-up, vacuum bag infusion, pre-pregs
5-Exothermy and Green Time issues
6-Introduction to the Classic Laminate Theory: mechanics of composites
7-Composites materials according to Classification Societies Rules
8-Approximations to determine the stress distribution for stiffenres considering plane stress condition
9-Elastic stability issues for thin walled composites
10-Repairing of composites and fire protection

All class schedules are posted on the EasyAcademy portal.
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.
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.
