The goal was a fastener strong enough to fasten a composite part, but also be cost-competitive and amenable to high-volume production. “Attachment to metal floors can be easily industrialized using fully robotic processes,” says Bernard. “So the idea for IMTEC HR was an industrialized solution for composites with no manual operations.” IMTEC HR fasteners can be placed into the mold for a composite floor structure and integrated during the molding process. Bernard cites IMTEC HR as compatible with thermoset and thermoplastic molding processes, including resin transfer molding (RTM), compression molding and injection molding/overmolding.

It’s time to plan your Wisconsin trip: Oshkosh 2018 is coming

 

There’s nothing else quite like it. The annual EAA AirVenture event is an air show/aircraft exhibition/trade show/learning opportunity/history lesson/concert venue/giant campout/Wisconsin bratfest (I could go on), held at Wittman Field in Oshkosh, WI, US. As always, the event’s organizer, the EAA (Experimental Aircraft Assn.), will offer hundreds of events and activities, from July 23-29.

According to the FAA, a commercial aircraft is on average struck by lightning once a year. With the growing use of composites in place of metal for major aircraft structures, lighting strike protection (LSP) is a critical requirement. Lightning can create serious risks to the structural integrity of the aircraft and to the safety of its passengers. Lightning strike protection is required to provide an effective means of safely dissipating the energy when a strike occurs.

Pickleball Central (Kent, WA, US) and the Composite Recycling Technology Center (CRTC, Port Angeles, WA, US) on June 21 announced availability of a new portable pickleball net system known as the SwiftNet. The new net system uses a patent pending design to transform how quickly and easily a pickleball court can be set up. The portable nets are made from recycled aerospace grade carbon fiber, making them about half the weight of other portable net systems available. With a carbon fiber boom and pole design, the SwiftNet can be setup by one person, in just a few minutes. 

David Walter, CEO of the CRTC, says, “The CRTC is honored to have worked closely with Pickleball Central on the development and launch of this excellent product into the market. We believe customers will appreciate how quickly the lightweight system sets up and how it responds like a tournament net. It is an excellent offering that is helping to keep scrap carbon fiber out of landfills, creating jobs, and giving our customers far more places to play this rapidly growing sport.”

An under-appreciated industrial application

 

A humble industrial application, manholes and trench access covers, has turned out to be a cost-effective and successful venture for Fibrelite (Skipton, North Yorkshire, UK, an OPW Company, Hamilton, OH, US), one of several suppliers of composite manhole covers. Fibrelite, in 2014, teamed with precast concrete trench manufacturer Trenwa Inc. (Ft. Thomas, KY, US) in a strategic partnership to create a combined product offering: Trenwa’s heavy-duty precast concrete road crossing trenches topped with Fibrelite’s traffic-rated composite trench covers. Together the two products provide long-term protection for underground utilities running across road crossings while enabling safe and fast manual access for monitoring and maintenance. CW reported on the partnership in 2014: https://www.compositesworld.com/news/fibrelite-trenwa-launch-new-composite-trench-covers. Fibrelite’s engineered composites replace metal and concrete materials, to solve manual handling and lifting injuries as well as corrosion issues associated with heave legacy covers.
