Fiberline Calculation Program. V-notched shear testing of composites. Many test methods are available for measuring the shear properties of composite materials.
The V-notched methods are currently among the most popular, in part because they can produce a relatively pure and uniform shear stress state in the test specimen, and they can measure the shear modulus and shear strength for the in-plane and interlaminar material orientations. Royal Engineered Composites Acquires "Time Reversal" Technology - NetComposites. Royal Engineered Composites (REC) is the first North American Aerospace Composites company to add "Time Reversal" technology to their nondestructive inspection capabilities.
According to Royal, this "time reversal" technology, as it is called by Zetec, utilises a unique phase array ultrasonic technology to vastly improve efficiency and flexibility for inspection solutions. Royal says it continues to position itself as a leader in technology for the future and for growth. This forward look keeps Royal's employee owners advancing into new opportunities and positions everyday while creating a consistent need for new employee owners to join the team. Using Lightweight Advanced Composites for Rail Applications.

Composites Vacuum Bagging Process. When manufacturing with composites, the material is made at the same time as the structures.
The material is cured under controlled conditions, controlled for heat, pressure, and vacuum. Carbon composite spring: Big performance, small package. Helical coil springs are a mainstay in today’s automotive suspensions, with a basic design essentially unchanged since their advent.
MW Industries (Rosemont, IL, US) is the largest US spring manufacturer/supplier and the largest supplier of high-performance springs to motorsports through its Hyperco division (Pontotoc, MS, US). Space Launch System. GKN Aerospace will work on Clean Sky 2 aeroengine projects. Industry News GKN Aerospace will work on Clean Sky 2 aeroengine projects The company will employ a number of processes and technologies to create the parts, with the goal of lowering weight by 15-30%.
China innovates in large composite materials helicopter blade molding. Therefore, in recent years, composite materials has more and more replaced metal in the blade manufacturing.
This has become an important development direction in the helicopter manufacturing and the composite materials fields. MAN Truck & Bus Extends Supplier of Choice Agreement with Hexagon Composites - NetComposites. Hexagon Bus Systems has been nominated by MAN Truck & Bus for the continued supply of compressed natural gas fuel systems.
Composite Pipe Battle Heats Up. Aging by moisture and/or temperature of epoxy/SiC composites: Thermal and mechanical properties. Facebook Build Carbon Fibre Aircraft to Provide Internet Access. Around 40% of the world is currently connected to the internet and Facebook are looking to connect the rest of the world with affordable and accessible internet.
Connecting people poetically in remote areas using traditional methods is a very costly business. One in five people globally lives in extreme poverty, existing on $1.25 per day or less. While progress has been made in connecting more than 90% of the world’s population to 2G networks, getting to 100 percent using conventional approaches is unlikely to happen in the near term.
Facebook is looking at solving these problems and are developing a range of new technologies, including high-altitude aircraft, satellites, free space optics, and terrestrial solutions to help accelerate the process of bringing connectivity to the unserved and underserved. Le planeur stratosphérique pressurisé Perlan 2 a effectué son premier vol. Perlan 2, premier aéronef sans moteur au monde conçu pour atteindre les portes de l’espace, a réalisé le 23 septembre son vol inaugural, avec une ascension à 5 000 pieds (1 500 m) au-dessus de Roberts Field, l’Aérodrome municipal de Redmond, dans l’Oregon.
Ce vol d’essai était le premier de cet aéronef, qui tentera l’année prochaine d’établir le nouveau record du monde d’altitude, toutes catégories confondues. L’objectif de ce projet consiste à réaliser de nombreuses découvertes dans les domaines du vol stratosphérique, du changement climatique et de l’exploration spatiale. Le planeur Perlan 2 a été développé par « The Perlan Project », une association à but non lucratif dirigée par des personnalités du milieu de l’aérospatial et de l’ingénierie. Elle est soutenue par Airbus Group et plusieurs autres sponsors, tels que Weather Extreme Ltd., United Technologies et BRS Aerospace. » Explaining electrical resistivity effects in electro-conductive polymer composites. Morphological analysis of saponified carbon-black-filled semi-crystalline polymers provides a new theory for positive and negative temperature coefficient phenomena.
Terminator style self-healing composites for soldiers patented this week. The drive towards designing the “high-tech” solider and combat vehicle is fueling development of new material technologies that rival the revolution in materials seen during World War II, when the modern plastics industry was created. Composites Manufacturing Magazine. Composite parts are widely used due to their unique properties, including durability. Unfortunately, even the best designed and best made parts can be damaged by unforeseen circumstances either at the OEM or in service. The following steps cover best practices for repair of anything from gel coat gouges or scratches to damage penetrating through the entire laminate. Before starting, put on the appropriate personal protective equipment for the task, including protective clothing, safety glasses, gloves and a respirator.
Step 1: Evaluate the work area. New patents issued for ultrasonic inspection technologies for airframe structures. Industry News New patents issued for ultrasonic inspection technologies for airframe structures The patents cover a robotic inspection system that uses a pair of cooperating, multi-axis robots mounted on linear slides to perform ultrasonic inspection of parts.
