Comment: Project No. POIR.04.01.04-00-0034/18 co-financed by the European Union from the European Regional Development Fund under the Smart Growth Operational Program for 2014-2020.
Project leader: Lodz University of Technology/Faculty of Chemistry
Partners: S. and A. Pietrucha sp. z o.o. Łukasiewicz – Institute of Textiles
Implementation: 01/12/2018 - 30/11/2020
Description: The result of the project will be the implementation of a product innovation in the Applicant's business in the form of a significantly improved product, i.e. hybrid geotechnical profiles with designed properties, for use in the field of civil engineering as retaining and measuring walls. In order to achieve the intended goal of the project, the Applicant envisages carrying out a number of research and development works, which will be focused mainly on the following technological areas: a) Selection of the appropriate reinforcement (reinforcement and compatibilizer) and optimization of mutual cooperation and durability of the materials used in the hybrid composite, their strength both at the phases as well as in the entire structure, thanks to which the composite on an industrial scale will obtain mechanical properties improved by at least: • 35% compared to the Young's modulus value for the GWF700 profile (PVC sheet pile reinforced with hybrid glass fibre), which is 4.3 GPa • 25% compared to the value of the maximum bending moment for GWF700, which is 56 kNm/m Obtaining the indicated mechanical properties will significantly extend the applicability limit of PVC-based sheet piles and will enable the use of an innovative hybrid sheet pile, named for the purposes of this project 700FR++, for the construction of retaining walls with a high bones up to 3 m above the ground surface. b) Selection of an appropriate sheet pile stress monitoring system and technology for integrating optical fibers with the composite, thanks to which it will be possible to equip the product with modern functionalities related to permanent structural monitoring. Equipping the product with innovative features and functionalities will be without prejudice to the basic advantages of vinyl sheet piles, such as e.g. relatively low weight, resistance to corrosion and most chemicals. Thanks to this, the result of the project will be a real alternative to light steel sheet piles, which are currently used to build retaining walls exceeding 1.5 m.
