Loss factors of honeycomb sandwich structures: an experimental approach
Loss factor measurements were performed on different sandwich panels to determine the effects of different skin and core materials on the acoustical properties of sandwich structures. The study included the following panel/beam designs: glass-epoxy skin with a meta-aramid (m-aramid) core, glass-epoxy skin with a para-aramid core, carbon skin with a m-aramid core, carbon skin with a m-aramid cor...

متن کاملQuasi-Static Three-Point Bending of Carbon Fiber Sandwich Beams With Square Honeycomb Cores
Sandwich beams comprising identical face sheets and a square honeycomb core were manufactured from carbon fiber composite sheets. Analytical expressions were derived for four competing collapse mechanisms of simply supported and clamped sandwich beams in three-point bending: core shear, face microbuckling, face wrinkling, and indentation. Selected geometries of sandwich beams were tested to ill...
متن کاملOnline Guided Wave-Based Debonding Detection in Honeycomb Sandwich Structures
Because of the complex nature of structural characteristics, damage detection in honeycomb sandwich structures inherently carries many challenges. In the study, effects of debonding on leaky guided wave propagation in honeycomb sandwich structures are first studied by using the finite element method. A surface-bonded piezoelectric wafer actuator/sensor network is used for elastic-guided wave pr...
متن کاملPerformance of metallic honeycomb-core sandwich beams under shock loading
Stainless steel square honeycomb core sandwich and solid monolithic beams have been subjected to high-pressure, short-duration impulses using a shock simulation technique involving high-speed impact of Al foam projectiles. The experiments have been designed to achieve two objectives: (i) to demonstrate the benefits of sandwich construction, and (ii) to assess the fidelity of dynamic finite elem...
