NEWS 37 CompositesWorld.com MVC Wall System length to accommodate transportation by container or truck, panel dimensions can be varied. For example, MVC supplied narrower 2.5m wide by 7.5m long panels to form the lower (inner) surface of the parachute-shaped Carrasco International Airport terminal (photo, p. 35). Further, the 22,000m 2 of panels did not differ in appearance, but were split between three designs, according to wind resistance requirements. Areas inside the terminal at the structure's center were not exposed to wind, but those in outer regions were, and had to resist additional loading. Ensuring that system components can meet the structural requirements of each project was MVC Plasticos' greatest chal- lenge, says Mussio. "Developing the MVC Wall System was very difficult because there were no internationally accepted standards to make the static calculations for the pultruded structural system components," he explains. "We needed proof of our construction methods and the load-bearing capabilities." Additionally, compos- ites are designed with different compositions based on the types of fibers, reinforcement patterns, resins and processes used. "So there are many, many possibilities to produce the same structural profile," says Mussio. "is variation in materials produces large variations in strength and stiffness, the structural properties. To overcome this challenge, we had to make many prototypes, physi- cally test them and then provide not only our structural calcula- tions, but also all of our own test data." But the extensive development has become a plus. "Now we are benefitting," he explains, "because, for Germany, we can send all of our test data and they can verify our calculations and structural performance, and compare that with other systems." is also was key in the selection process used by Brazil's National Program to Restructure and Equip the Public School System (PROINFÂNCIA). "Our constructions were verified as technically superior to projects using conventional construction systems," says Mussio. MVC has made a significant investment in order to ensure its system is readily usable by the construction industry worldwide, including a dedicated design and development center, an exten- sive and well-equipped material and physical testing laboratory and a staff of civil and structural engineers. e latter have enabled development of all the fixation and installation details, which are explained and illustrated by the necessary drawings and reference documents for each project. Advantage for the underserved MVC's combination of superior performance and speed of delivery is a definite advantage, and not one typically enjoyed by the students and families who benefit from these composite construction projects. But the value is undeniable. For example, in 2011-2012, the MVC Wall System was used to rebuild 35 schools in 12 municipalities that had been destroyed by heavy heavy loads love light support Trunk and cargo load floors made with BASF polyurethane chemistry offer the best of all worlds. Less added weight, superior strength and maximum stability. Plus, our unique polyurethane chemistry combined with paper honeycombs saves space, reduces sound and vibration, provides good adhesion for substrates, and resists heat and wear. Big idea – small package. Because at BASF, we create chemistry. Learn more at www.automotive.basf.us
