Bombardier chooses Alcan’s AIRWARE(TM) technology for its CSeries aircraft program in the framework of a long-term agreement

PARIS, July 20 /PRNewswire/ – Alcan Global ATI and Bombardier, one of the world’s largest aircraft manufacturers, have entered into a long-term agreement for the exclusive supply of AIRWARE(TM), Alcan’s advanced aluminum-lithium alloy technology, to provide primary structure for the all-new CSeries aircraft. AIRWARE(TM) will comprise more than 20% of all materials used in the CSeries aircraft.

AIRWARE(TM) technology, which is based on the mastering of low density alloys, has helped Bombardier develop a high-strength, light, metallic fuselage by combining sheets and extrusions to manufacture fuselage skins, stringers, frames and floor beams. This contributes to significant improvements in aircraft operating costs, fuel consumption and emissions reduction.

“With AIRWARE(TM), we pave the way for a revolutionary utilization of aluminum-based technologies to design lighter, greener aircraft, whilst ensuring the highest level of reliability, which is a key requirement in the aerospace industry,” said Christophe Villemin, Alcan Global ATI President. “Thanks to collaborative research and development, initiated with Bombardier in 2007, Alcan has been chosen as an exclusive supplier of AIRWARE(TM) for the CSeries aircraft program,” continued Villemin.

Bombardier’s single-aisle CSeries aircraft, which is designed for the 100- to 149-seat market segment, is expected to offer a 15* per cent cash operating cost advantage over current in-production aircraft. Advanced materials will contribute to the CSeries aircraft’s 20% fuel consumption advantage and reduced CO2 emissions.

AIRWARE(TM)’s low density, exceptional mechanical properties and inherent electrical conductivity allows significant weight reductions compared to competing materials. In addition, AIRWARE(TM)’s unparalleled corrosion resistance, strength and behaviour predictability will all contribute to easy maintenance of CSeries aircraft.

In line with Alcan and Bombardier’s commitment to sustainability, AIRWARE(TM) material removed during machining can be infinitely recycled into new aircraft parts, as can all AIRWARE(TM) components when an aircraft reaches the end of its commercial life.

“This long-term agreement demonstrates Alcan’s leadership and commitment to provide the aerospace industry with step-change turnkey solutions to reach ever more challenging economic and environmental objectives,” concluded Villemin.

Concrete columns with internal bars made of glass fibers can make a building sturdier

Washington, July 15 (ANI): A new research has determined that concrete columns with internal bars made of glass fibers can make a building sturdier.

In the research, the University of Miami, through its NSF Industry/University Cooperative Research Center “Repair of Buildings and Bridges with Composites” (RB2C), performed the first-ever tests of full-scale concrete columns internally reinforced with glass fiber reinforced polymer bars.

Conventional means of internal reinforcement for concrete member in buildings involve steel bars.

Yet for structures that function in harsh environments like coastal regions, or for structures that support sensitive equipment, such as magnetic resonance imaging units; the use of fiber reinforced polymer (FRP) is emerging as a valuable option, due to its natural resistance to corrosion, its high strength, light weight, transparency to electrical and magnetic fields and ease of manufacturing and installment.

However, little has been done to study the performance of concrete columns reinforced with FRP bars.

Full-scale experiments are critical to validate the technology, and to produce compelling evidence that underpins rational design methodologies.

To address this need, the National Science Foundation (NSF) Industry/University Cooperative Research Center RB2C at the University of Miami (UM) examined the behavior of concrete (RC) columns internally reinforced with glass FRP (GFRP) bars on full-scale specimens for the first time ever.

The new study demonstrates that the behavior of GFRP-RC columns was very similar to that of the conventional steel counterpart.

“The outcomes of our study provide a compelling case to modify existing design guidelines and allow for limited use of GFRP bars in columns, particularly when corrosion resistance or electromagnetic transparency is sought,” said Antonio De Luca, graduate student at the University of Miami College of Engineering.

The next stage of the study is meant to demonstrate that specimen scale does not affect GFRP-RC column specimen performance; and to investigate the behavior of GFRP-RC column specimens subjected to compressive load applied with a small eccentricity. (ANI)
