HP-RTM for serial production of cost-effective CFRP aerostructures: CompositesWorld

CTC has demonstrated HP-RTM parts with 60-percent fiber volume and less than 2 percent voids, molded in 20 minutes, such as this 1.5-meter-by-0.5-meter CFRP rib, representing possible aerospace primary structures. Working with Airbus Helicopters and KraussMaffei in the SPARTA project, Alpex Technologies designed and built HP-RTM tooling using automotive best practices, which was used to produce a demonstrator frame for the Airbus A350 passenger door, currently manufactured by Airbus Helicopters using low-pressure RTM. RTM tooling for the A330 spoiler hinge fitting in action, illustrating Alpex’s experience and innovation. When resin transfer molding (RTM) began transitioning into high-pressure RTM (HP-RTM) roughly a decade ago, it was mostly lauded for automotive applications, reducing composite part cycle times from hours to less than 2 minutes. Less has been said about applying this technology to aerospace parts. The aircraft industry has a long history with conventional RTM, including its use to produce thousands of carbon fiber-reinforced plastic (CFRP) fan blades and containment cases for commercial aircraft engines. Airbus has even prototyped a 7-meter-long, one-piece co...

The young staff policy at TAIF GC companies — RealnoeVremya.com

According to data in the report for 2018, the total number of workers of all companies included in TAIF GC is over 38,000. And the majority of them are concentrated in four key companies: Nizhnekamskneftekhim PJSC, Kazanorgsintez PJSC, TAIF-NK JSC and TGC-16 JSC. Read in Realnoe Vremya’s report about the staff policy of the TAIF GC enterprises, focus on the youth’s professional training and how a productive dialogue between the older and younger generations of employees is held. Popularisation of vocational jobs is one of the tasks that are actively performed at the federal and regional levels: “What we certainly, absolutely certainly should pay special attention to is the work with staff on training of world-class vocational specialists,” President of Russia Vladimir Putin stressed at a meeting of the State Council on improving the investment appeal of the Russian regions in December 2017. “The training of sought-after vocational specialities must be done in close cooperation with potential employers and equipment suppliers,” President of Tatarstan Rustam Minnikhanov claimed when giving a speech in front of the participants of the plenary session of the republican meeting of ed...
