In order to respond to the training needs of the professionals who work in this area, the new PG in Composite Materials offers a compact and post-work schedule, which consists of specific modules in Composite Materials, where topics such as production, repair and recycling of composite materials, design of laminated composites, namely sizing and connections. This training also allows to extend the technical skills of the participants in the PG in terms of adhesives and surface treatment, essential to the bond between composite and composite parts with metal, design and material selection and product development in composite materials. PG also includes a practical component on the manufacture of laminated composite materials and their thermal, chemical and mechanical characterization, performed in Atlântica laboratories.
Interested students will be able to carry out a study visit to the Carbures factory in Jerez de la Frontera (Spain) where they are made composites for Airbus, but also parts for cars, motorbikes and trains. During the visit they will have contact with leading technologies and will follow the production process from the reception of raw materials to the shipment of the pieces.

Adhesives, Adhesives and Surface Treatment
Since composites are one of the most industrially applied structural materials, the study of the bond between composites and composites with other materials such as metals or plastics is fundamental for the production of composite structures. The use of adhesives for this purpose, in addition to presenting several advantages, has allowed the joining of materials hitherto unthinkable. For this reason, in this module a comparison will be made between adhesive bonds and mechanical joints, highlighting the respective advantages, drawbacks and failure modes. The grounds underlying the accession process and their quantification will also be presented.
For the end of the module the student is able to select the most suitable adhesive technology for a given application (composite-composite or composite-metal bonding), the necessary knowledge will be transmitted to:
- selection of the most suitable adhesive, through the study of the basic requirements of the adhesive bonds, the types of structural adhesives, their properties and applications;
- design of the adhesive joint, which requires the knowledge of the adherent materials and the study of the distribution of the forces that will act on the adhesive bond resulting from the use of the composite;
- surface treatment of adhesives for the optimization of the adhesive joint;
- manufacture of the joint, which will address the application, thickness control and adhesive cure processes;
- control of the process, which aims at the analysis of the quality of the adhesive joint through characterization tests.
In this module will also be approached the self-regenerating adhesives (in the study and development phase) that, by allowing the self-repair of joints, prolong the time in service of the composite parts.
Design of Laminated Composite Materials
In this module, it is intended that the student acquire substantial knowledge about the design of structures in laminated composite materials from the point of view of their applications, namely in components of aeronautical structures. More specifically, it is able to optimize the laminated composite materials according to the requirements of its application, taking into account the scientific / technological fundamentals and the computer modeling techniques learned. As a result of the learning it is expected that at the end of this module the students:
- develop an understanding of the phenomenological aspects of the behavior of composite materials
- understand the mechanisms of failure when subjected to different mechanical and environmental stresses
- to critically analyze the factors that affect the performance of materials and structures.
Design and Selection of Materials
It is intended that students acquire a basic training on methodologies for selection of materials and processes and their framing in the design, design and manufacture of new products (such as selecting materials and processes for a given application in the field of Aeronautical materials). At the end of this curricular unit the student should be able to understand:
- the complexity of the selection process of materials and processes
- develop strategies to approach various cases of materials selection and processes based on tools available in the market
- the limitations of these selection tools
- develop a critical analysis of the results obtained
It is also intended that the student make contact with the methodologies for designing new materials for aeronautics based on materials science, application requirements and economic, environmental and social criteria.
Technological Product Development
The curricular unit is designed to create competencies in the design and development of technological products, closely related to the market needs and customer requirements, focusing on the design, design, development, production and commercialization of technological products. specialty.
It is intended that, upon completing this curricular unit, the students:
- understand the importance of product - market - process (PMP) alignment in product development;
- know the various stages of the product development process, its definition, work units, milestones, outputs and decision criteria that allow progression through the process, culminating with the market introduction.
- understand the importance of strategic planning and proper management of I
Manufacturing and Characterization Laboratories of Composite Materials
This module is intended for students to have contact and gain experience in some of the technologies used in the production of composites and in the respective thermal, chemical and mechanical characterization. In this context, laboratory classes are planned where students will have contact with different techniques, namely:
- Infrared spectroscopy (FTIR) for chemical characterization and quality control of the Composite Materials matrix
- Molding and vacuum for the production of composites
- Thermogravimetric analysis (TGA) for thermal analysis and quantification of the fiber and resin present in the Laminated Composite Material
- Characterization of adhesive joints by measuring thickness and adhesion strength through pull-off equipment
- Mechanical characterization tests of composite materials laminated by universal tensile and bending tests.
