JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
Park Electrochemical Corp. announced on the 10th of October 2011 Sigma Strut™, the new name for its patented composite strut design. A strut is a structural load carrying element which transfers loads between two points. The Sigma Strut design provides significant weight savings compared to metal struts and other composite struts.
The Sigma Strut design utilizes a unique metal end-fitting, which is co-cured into each end of the strut without the use of adhesives. This technique allows the fittings to carry the full load of the strut body without having to rely on bond areas to carry shear loads as with typical designs.
Sigma Strut designs have been qualified for use on programs such as the Kistler Aerospace K-1 launch vehicle, NASA Space Shuttle Orbiters and NASA’s Max Launch Abort System (“MLAS”) program which was developed with Northrop Grumman Corporation. NASA has also tested the Sigma Strut design as part of the Structurally Efficient Tapered Strut (“SETS1” and “SETS2”) programs in an effort to select one design to use across multiple NASA programs. In each of these programs the Sigma Strut design was chosen for its ability to meet all of the program requirements while still being the lightest solution available.
