Currently, modular construction has major advantages over traditional construction, particularly in terms of standardization of the elements, series production, rationalization, elimination of waste and time savings in a large number of construction elements.
It is therefore possible to promote the construction of houses at controlled costs, for zones and Peoples of the World in which their economic and social condition does not allow the purchase of a house with health, comfort and hygiene conditions consistent with the needs of the Human Being.
Innovation
Fibrenamics - University of Minho in collaboration with GUIMAR company, has developed a sandwich panel based on fibrous materials for modular home construction.
This panel, used to build the walls and ceilings of modular housing is extremely light, allowing an economic transportation and a quick and easy assembly. In addition, both the panels and the houses, have been developed in a perspective of economic, ecological and social sustainability.
The panel is produced from natural fibers, which increase the thermal and acoustic performance of the panel and eliminates the need for chemical finishing of the surface imparting the panel the aspect of natural fibers.
Thus, taking into consideration the application requirements, various combinations of fiber/resin have been studied. These combinations have been characterized in terms of mechanical, thermal, acoustic, dimensional and fire resistance properties.
The study of the properties of various materials has led to the selection of the most efficient ones for the application. It was also performed the modeling of the panel in finite elements to obtain a technically efficient solution.
Results
The developed solution possesses the dimensions of 1000x2500x77 mm, with the following characteristics:
● Total weight less than 22 kg;
● Breaking load of 1600 kg (regular) or 2700 kg (distributed);
● Deformation of 9.2 mm (L / 250) for a load of 60 kg (regular) or 8.4 mm for a load of 40 kg (distributed);
● Thermal resistance of 0.87 (W / mºK).
Datasheet
The FMC_Panels project – Development of composite panels with fibrous-based materials for the manufacturing of modular homes (NSRF Project No. 21581), sponsored by Guimar company, was co-financed by the European Regional Development Fund (FEDER) through the National Strategic Reference Framework (QREN).
