MELVILLE, N.Y., 27 July 2013. Park Electrochemical Corp. (NYSE:PKE) is introducing its Alpha Strut patent-pending, proprietary composite strut design.
The Alpha Strut, designed for aircraft and other aerospace medium- to high-load-bearing applications, such as primary and secondary aircraft structures, tie rods, push/pull control rods, monument bracing, truss structures, and bulkheads.
The new offering extends Park’s product line, which includes the patented Sigma Strut aerospace composite strut designed for space and other aerospace very-high-load-bearing applications.
A strut, a structural load-carrying element, transfers loads axially between two points. The Alpha Strut and Sigma Strut designs provide weight savings and load carrying reliability compared to metal struts and other composite struts by using unique metal end-fittings, which are co-cured into each end of the struts without the use of adhesives. This technique enables the fittings to transfer the full load through the strut body without having to rely on bond areas to carry shear loads as with typical designs.
Alpha Strut designs have been developed to safely support working (limit) loads of 1,100 pounds in tension and compression with an ultimate load capability of 2,200 pounds.
