“…Kavianiboroujeni et al [108] focused on the mechanical properties of sandwich structures made of polyethylene/hemp face sheets and polyethylene core with/without azodicarbonamide foaming agent. In the continuation of their previous study, Kavianiboroujeni et al [109] studied low-velocity impact response of asymmetric three-layer sandwich panels with and without foam core.…”

In recent years, concerns about environmental pollution have led to the development of natural fiber sandwich structures as alternatives to petroleum-based ones. This paper reviews various studies on sandwich structures composed of non-wood cellulose-nature fibers. These fibers mainly include flax, hemp, jute, kenaf, sisal, coir, and bamboo. The studies are classified based on the type of fibers, the components in which they are used, and experimental tests/numerical investigations. Furthermore, a few suggestions for future research in the field of eco-friendly sandwich structures are made.

“…Results showed that this solution could improve the absorbed energy and penetration threshold of the foam-core composite panels. A comparative study between composite structures with and without foam core with regards to their impact behaviour was conducted by Kavianiboroujeni et al [16] on three-layer composite structures made of high-density polyethylene (HDPE) and hemp. Low-speed falling weight and Charpy tests were used to study the role of hemp content, skin thickness and density of the core material.…”

Structural Performance of Polyurethane Foam-Filled Building Composite Panels: A State-Of-The-Art

et al. 2019

Composite panels with polyurethane (PU) foam-core and facing materials, such as gypsum, engineered wood or some composite materials, are being used as structural members in building construction. This paper reviews and summarises major research developments, and provides an updated review of references on the structural performance of foam-filled building composite panels from 1998 to 2017. The review revealed that previous studies on the structural performance of foam-filled building composite panels could be categorised into five themes; namely, energy absorption and dynamic behaviour; bending and shear behaviour, edgewise and flatwise compressive/tensile behaviour; delamination/deboning issues; and finally some miscellaneous issues. These categories comprise approximately 30%, 40%, 11%, 11% and 8% of related studies over the last two decades, respectively. Also, over the past five years, the number of relevant studies has increased by ~400% relative to the previous similar periods, indicating the attention and focus of researchers to the importance of the structural performance of foam-filled composite panels.

“…1 Different materials such as foams, Nomex, Aluminum alloys, wood, laminated composites and polymers have been used to fabricate the core of sandwich panels. [1][2][3][4][5][6][7] The choice of core material depends on the application of these structures, load life, availability and cost. 1 Recently, 3D printing technology has been considered to manufacture the cores with remarkable mechanical properties and various patterns.…”

The main aim of this study is to investigate the effect of printed hierarchical-sinusoidal corrugated core patterns and the load direction on the flexural properties of the cotton/epoxy composites sandwich panels. For the cores, six sinusoidal corrugated structures were considered. Besides, possible arrangements (transvers or longitudinal wave, arch downward or upward) of the sinusoidal corrugated cores with respect to the loading direction were considered. Totally, 72 cores were fabricated using a 3D printer and poly lactic acid material. It was observed that for the transverse arrangement, the flexural strength of sandwich panels is significantly improved by changing the pattern from the simple form to the hierarchical patterns. In contrast, for the longitudinal pattern, improvement in the flexural properties was not obtained by changing the core pattern. It was also manifested that corrugated core arrangement has remarkable effect on the mechanical properties of the sandwich panels. For the transverse pattern core panel, the maximum values of normalized face-sheet bending strength (FBS), core shear ultimate strength (CSUS) and energy absorption were obtained as 7.17 MPa/kg, 223.91 MPa/kg and 114.56 J/kg, respectively. Besides, for the longitudinal pattern core panel, the maximum values of FBS, CSUS and energy absorption were obtained as 7.86 MPa/kg, 245.78 MPa/kg and 330.75 J/kg, respectively. Comparing the obtained results with the available data in the literature manifested that the flexural properties of the corrugated core sandwich structures are significantly improved by changing its core system from the other materials to the printed material.
