HiMax glass fibre fabrics by Hexcel Reinforcements UK, a leading manufacturer of composite reinforcements, specialising in lightweight carbon fibre multiaxials and highly engineered glass fibre and aramid fibres, have been selected by Greek company Dasyc SA for the manufacture of its Composite Modular Transportable Hangar (CMTH).
Constructed from prefabricated composite sandwich panels, this innovative structure can be employed in a wide variety of civil or military applications. The use of Hexcel quadaxial reinforcements enabled Dasyc to manufacture a composite structure with a strength equivalent to that of a concrete or steel building.HiMax glass fibre fabrics by Hexcel Reinforcements UK, a leading manufacturer of composite reinforcements, specialising in lightweight carbon fibre multiaxials and highly engineered glass fibre and aramid fibres, have been selected by Greek company Dasyc SA for the manufacture of its Composite Modular Transportable Hangar (CMTH).Constructed from prefabricate#
Dasyc developed the composite hangar to address a need for mobile storage, parking and housing structures. The patented design enables rapid transportation, assembly and disassembly in any location. Possible applications for the structures range from housing aircraft, helicopters and military vehicles, to the storage of equipment at construction sites or airports.
To create the CMTH hangar, the composite panels are assembled together to form arches. The length of the hangar is dependent on the number of arches used. The panels are manufactured at Dasyc's production plant in Markopoulo using a vacuum assisted resin transfer moulding (VARTM) process. They are 80 mm thick sandwich structures consisting of a hard polyurethane core material between two laminate skins of glass fibre reinforced polyester resin.
For this project Dasyc required reinforcements that would form a composite structure with strength similar to that of a concrete or steel building and capable of withstanding the same structural loads as specified by the Eurocodes building regulations. To provide the required mechanical properties Hexcel Reinforcements UK supplied its HiMaxTM quadaxial fabric, consisting of four layers of e-glass fibres aligned in the 0°/-45°/90°/+45° orientations and stitched together with polyester thread. Four layers of fibres were used in each skin. In addition to imparting excellent structural support and stiffness to the laminate, quadaxial fabric is a cost effective solution for reducing labour in the lay-up process as it is possible to apply multiple layers simultaneously.
