A representative of RTU is appointed to the Board of the Most Influential Innovation Council in Europe

Liene Briede, Acting Director of the Science and Innovation Center of Riga Technical University (RTU), has been confirmed as the first representative of Latvia in the Board of the European Innovation Council. The Council, set up this year, is Europe’s largest innovation initiative to boost research, innovation and start-ups to bring Europe a technological breakthrough.

The European Commission has appointed 20 leading researchers, entrepreneurs, business leaders, innovation ecosystems and innovation experts with expertise in Europe’s future innovations, including digital technologies, healthcare and green transformation, to the Board of the European Innovation Council (EIC). More information.

L. Briede is the only representative of Latvia in the newly established council, to which more than 430 specialists applied. The European Commission has assessed her ten years of experience in improving the Latvian and Baltic innovation ecosystem by implementing and improving various business development and support programs at RTU, such as pre-incubation, incubation and acceleration activities for students, researchers and start-ups. Under her leadership, the activities of the European Institute of Innovation and Technology (EIT) knowledge communities EIT Climate-KIC, EIT Food, and EIT RawMaterials have also been implemented in Latvia, increasing the innovation capacity in various sectors of the economy.

“Following the development of the innovation ecosystem in Latvia and Europe, I see the need to change the focus from technology-based processes to human resource development processes. Scientists and innovators create many technologies, but not all of them enter the market. An essential precondition for the commercialization of science-intensive solutions is the cooperation of specialists from different fields and levels, a unified motivation and value system, as well as a systemic approach to the implementation of support processes, »emphasizes L. Briede.

She said that the new board would review European innovation policy, evaluate the functioning of EIC instruments and, if necessary, propose new solutions that would ensure a more efficient exchange of knowledge and the development and implementation of innovative solutions. “Membership in the Board will ensure Latvia’s representation and more active involvement in the global innovation ecosystem. Latvia ranks one of the last places in the use of EIC tools. Participation in the board opens up an opportunity to become an “interpreter”, ie to explain the needs of Latvia and other small countries to European innovation policy makers, and the opportunities and benefits of EIC to members of the Latvian ecosystem, “L. Briede continues.

RTU has a developed innovation environment that offers knowledge, support in product development, as well as various tools for the development of ideas from the early stage to the global conquest. With the continuous improvement of this system, the RTU Science and Innovation Center has almost been established, which will promote both the involvement of students and academic staff in the transfer of knowledge and the creation of innovations, as well as cooperation with industry in the creation of high value-added products.

The European Commission announced the establishment of the council this spring. The EIC has a budget of more than ten billion euros for 2021-2027.

RTU extends the deadines for study semesters

With the Rector’s order, Riga Technical University (RTU) extends the deadline for the end of the spring semester up to 14 August, whereas a new academic year will start on 14 September. Such a decision has been taken in order to enable students to perform all study assignments and laboratory works, which have been delayed due to the emergency situation caused by Covid-19, in a qualitative way.

The extension of the study semester does not at all mean that all students of RTU will have mandatory studies until 14 August. RTU study programmes differ — some of them can be completed earlier, possibly even in June, whereas for others, especially programmes in engineering sciences, it is required to perform laboratory works, which, unlike lectures, cannot be performed remotely.

The RTU diploma confirms that the university prepares high-skilled engineering and high-tech specialists and, therefore, even in extraordinary circumstances, the RTU study process should be carried out in full volume and students should acquire practical skills in working with special equipment, in order to be fully prepared for the labour market.

To achieve this, the set examination session period scheduled from 25 May to 21 June has been cancelled, and the nine faculties of RTU will have flexible planned schedules for lectures and exams to allow students completing this semester as soon as possible.

The deadlines currently set for the semesters can still be changed, depending on the deadlines and conditions prescribed by the government for the emergency situation.

RTU scientists are developing advanced technology for the production of composite materials

Scientists at Riga Technical University (RTU) are developing advanced technology to make composite materials used in construction and infrastructure, aeronautics, automotive and shipbuilding 30% more efficient and cheaper.

One of the most widespread and fastest growing composite materials in the world is pultrusion – when passed through a heated mold, fiberglass raw materials are impregnated with thermosetting resins. In Latvia, most of the resins are based on epoxy, polyester and vinyl ester. The pultrusion process produces a variety of bars, angles and double-T profiles, as well as curved profiles (with constant cross-section), such as wind turbine rotor blades. It is also possible to produce high-quality pelted profiles with protective coatings that are light and durable, with excellent mechanical and chemical properties, resistance to aggressive environments such as fire or corrosion. This is important in a variety of material applications, such as reinforced concrete, where composite bars and non-corroded gratings are used instead of metal reinforcement and are used intensively in port construction.

The traditional pultrusion process, which uses electric heaters to heat molds, has been known since the 1950s, when it was patented. Researchers of the Institute of Materials and Structures of RTU Faculty of Civil Engineering, under the guidance of Professor Evgeny Barkanov, in cooperation with Juvitek Ltd., are planning to significantly increase the efficiency of this process by using new heating sources, reducing production steps and real-time

The electric heaters used to date are characterized by high heat losses, so scientists suggest replacing them with high-frequency heat sources, namely microwaves. This would increase energy efficiency by 30%.

In turn, optimizing and automating the pultrusion process could reduce profile costs by up to 35%, scientists estimate. They develop an innovative in-line pultrusion process that combines several production steps, such as profiling, polymerization, surface preparation and coating, into one. This new idea will significantly increase production speed while reducing the number of employees involved in the process, says Pavel Akashin, a researcher at the RTU Institute of Materials and Structures. Advanced technology will also be more environmentally and human friendly by reducing volatile organic compound and fine particle emissions from the production of profiles and the application of coatings.

It is also planned to develop a combined prototype of in-line ultrasound and optical measuring equipment for quality control of pultruded profiles online. The equipment is required to ensure that the finished materials do not show cracks, pores and resins are fully polymerized.

The research project will generate new knowledge to improve the competitiveness of the Latvian economy, and its results and inventions will be useful to local and international manufacturers of thermosetting and thermoplastic composite materials and structures for the development of new high value-added products. These products will continue to promote the use of lightweight composite materials in various applications such as aeronautics, automotive and shipbuilding, construction and infrastructure.

The project “Improvement of the Effectiveness of Traditional Pultrusion Processes” (project no.1.1.1.1 / 18 / A / 053) is being implemented with financial support from the ERDF under the “Practical Studies” program. The project will be completed in 2022.
