While shape memory alloys (SMAs), such as nickel–titanium, have long been the most widely used SMMs due to their high actuation force and reliability, growing interest in new materials and possibilities has led to growing R&D investment in shape memory polymers (SMPs).

Figure 1. The most popular memory shape material is nitinol, a nickel titanium alloy used for vascular stents among many other uses, for their ability to withstand external compression forces.

One of the most promising evolutions in the field of shape memory materials is the development of shape memory polymer composites (SMPCs). By reinforcing SMPs with fibers, nanoparticles, or other functional fillers, researchers are expanding their mechanical strength, functionality, and environmental resistance—without sacrificing the inherent advantages of polymers, such as low weight and design flexibility.

These composites can simultaneously achieve high actuation strain and improved stiffness, conductivity, or thermal properties, opening the door to high-performance applications. Among the different families of shape memory polymers, epoxy-based SMPs (SMEPs) are attracting particular attention due to their excellent mechanical performance, thermal stability, and chemical resistance.

Epoxies are already well-known in structural and high-performance applications, and their transition into the field of smart materials is a natural evolution. SMEPs combine the adaptability of SMPs with the structural integrity of epoxy networks. Their highly crosslinked structure allows for precise programming of the shape memory behavior, while offering superior dimensional stability compared to thermoplastics. Current research is focusing on tuning their properties through tailored curing systems, molecular design, and hybrid formulations—resulting in systems with faster recovery, multi-shape capabilities, and even self-healing features.

There is no doubt that shape memory polymers and their composites will see increasing real-world applications in the future, opening up a new range of possibilities for smart materials.

In about 1200 AD, Mongols invented the first composite bows made from a combination of wood, bamboo, bone, cattle tendons, horns, and silk bonded with natural pine resin. These small, powerful and extremely accurate bows were the most feared weapons on earth until the 14th century invention of effective firearms.  

Composite Mongolian bows helped to ensure Genghis Khan’s military dominance during that period, in which its arsenal conquered huge chunks of central Asia and China!  

History shows us how the mastery of advanced materials has been extremely important, even for ancient civilizations!

Composite Materials are less of a choice and more an imperative. Metals and plastics might be the right solution for many engineering challenges. However, composites increasingly allow for a new range of possibilities and solutions! In this course, you’ll acquire a general overview about composites by understanding these materials in depth, including, different types of fibres, matrices, cores and fabrics. Learning the different manufacturing technologies and dive into the basics of composite design.

• WHAT YOU’LL LEARN

Overall, the course consists of 3 main blocks. First, all the materials are explained in detail. Different fibres, such as carbon, glass, aramid, polymeric, natural, are analysed. Then matrices are discussed with a focus on thermosets. Besides, different core and fabric types are discussed.

Second, once the materials have been understood, the course goes into the manufacturing technologies. Not only is each process illustrated but also why and when each technology is commonly used! In total 9 technologies are explained, including: Wet Layup, Prepreg, PCM, SMC/BMC, Resin Infusion, RTM, Filament Winding, Braiding and Pultrusion.

Third, the course has a design part. If we have fully understood how materials work and how we can manufacture, we can start thinking how to design with composites. The entire process is outlined, including, Concept Design, Manufacturing Process Selection, Part Design, Joints, Layup, Tooling, Curing, Post-Process and Design for Manufacturing

• WHO YOU’LL LEARN FROM:

Eneko Angulo, now Chief Operations Officer of Managing Composites, is the main trainer of the course. Previously he has been Station leader at Koenigsegg, manufacturing carbon fibre monocoques and body panels. He produced more than 450 reports to increase part quality for the Koenigsegg 1:1, Agera RS and Regera. Later on, he became SQA Manager at McLaren, being responsible for more than 300 components in different technologies and more than 8 models.

• SOME PRACTICAL INFORMATION:

The course is to great extent, online and self-paced, meaning that it consists of short videos explaining the theory and practice behind composites and tasks, quizzes, etc. to see whether the learner is making progress. However, sporadically there are online live sessions to consolidate the learnings. You’ll be able to send questions to the trainers through the platform.

Once you’ve completed the course, you’ll get a certificate of successful completion and have access to an ever-growing alumni network, as well as special discounts.

The price fee is set at €269 in a one-off payment. However, there is the option to pay for the course in 3 instalments of €99. Besides, if you are a student contact us for some special discounts.

In order to deliver a high-quality course, The Native Las has picked some of the best engineers of Managing Composites. Lluc Marti (CEO), Alejandro Batan (CPO), Marc Oliva (Lead Designer), Eneko Angulo (COO) and Ignacio Carranza (CAE Manager), who have gathered their experience working with composites and monocoques at companies like Koenigsegg, McLaren, Prodrive and Hyundai Motorsport.

The course is taught online and live, meaning that it is instructor-led. This allows for participants to ask the trainers directly about any doubts they have, leading to interesting group discussions and enriching the entire course. In total there will be 8 sessions and in case students cannot participate live they will have access to the recording of the live session.

Sessions:

1. Introduction and Basics of Monocoque Design
2. Packaging and Primary Functions
3. Concept Design and Secondary Functions
4. DFMEA
5. Detail Design
6. Structural Analysis
7. Post-Process
8. Final Q&A Session

Participating in the course gives access to the alumni network that includes job offers and discounts apart from a course certificate. The next edition will be starting on the 20^th of April 2022!
