Experimental and numerical investigation of core splicing configurations in an advanced composite sandwich structural system

Rawan Aqel et al.

Summary: This study investigates the effects of honeycomb core splice gaps on the performance of composite sandwich structures with aluminum honeycomb core and carbon-fiber/epoxy facesheets. The experimental and numerical investigation explores the influence of core thickness, facesheet thickness, splice gap width, and core splice adhesive on the structural response. Results show the importance of proper detailing and analysis of core splices in sandwich composite structures.

Carbon fiber reinforced plastics with aluminum honeycomb core design methodology for space and surface mining applications

Patrick Severson et al.

Summary: This paper introduces the application of sandwich composite materials in space mining and proposes the development of selection charts to define the material system, facilitating wider use of these materials in the mining industry. Additionally, a numerical modeling approach for thick section sandwich composites is presented, allowing for rapid design iterations.

Experimental and numerical investigations of two-way LVL-concrete composite plates with various support conditions

Joonas Jaaranen et al.

Summary: This paper investigates the behavior of two-way LVL-concrete composite plates and a plate strip, focusing on the performance of proposed dovetail joint for connecting the adjacent LVL panels. The results show that supporting all four edges significantly improves the two-way action, and the dovetail joint can produce a stiff connection.

Effects of core splice joint width on the performance of composite sandwich structures with honeycomb core: An experimental study

William E. Guin et al.

Summary: The study shows that there is a critical threshold for core splice joint width in honeycomb sandwich structures related to core shear, and the integrity of the facesheet-to-core interface degrades as the core splice joint width increases.
