Park Electromechanical Corp. (Melville, N.Y., USA) announced on July 22 the introduction of ALPHA STRUT, the company's 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, which is designed for space and other aerospace very-high-load bearing applications.

The ALPHA STRUT and SIGMA STRUT designs are said to provide significant weight savings and load-carrying reliability by using unique end fittings, which are cocured into each end of the struts. 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 other designs.

Park say the ALPHA STRUT design has been successfully tested to more than 1 million load cycles at load limits in both tension and compression. Applications include tie rods, push/pull control rods, bracing, truss structures and bulkheads. Features include high reliability, proprietary end-fitting design, light weight, carbon fiber composite and custom designs tailored to specific loads, lengths and fitting requirements.
