Park Electrochemical Introduces New Composite Alpha Strut for Aerospace Applications

06 August 2013

Park Electrochemical has introduced Alpha Strut, a new proprietary composite strut design.

The Alpha Strut, which is designed for aircraft and other aerospace medium-to-high load bearing applications, joins Park’s patented Sigma Strut in Park’s proprietary aerospace composite strut product offering. The Simga Strut is designed for space and other aerospace very high load bearing applications. A strut is a structural load carrying element which transfers loads axially between two points. The Alpha Strut and Sigma Strut designs provide significant weight savings and load carrying reliability compared to metal struts and other composite struts by utilising unique metal end-fittings, which are co-cured into each end of the struts without the use of adhesives. This technique allows 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. The Alpha Strut design has been successfully tested to over one million load cycles at load limits in both tension and compression. The Alpha Strut is suitable for a variety of aircraft and other aerospace medium to high load bearing applications, including primary and secondary aircraft structures, tie rods, push/pull control rods, monument bracing, truss structures and bulkheads. The Alpha Strut utilises fully traceable materials which are acceptable for aircraft and other industry use.
