How do different adhesives affect the properties of sandwich panels?5 answersDifferent adhesives have varying effects on the properties of sandwich panels. The addition of MWCNTs to polyurethane adhesive enhances the thermal stability, flat-wise tensile strength, and edge-wise compression strength of sandwich structures. Increasing the adhesive quantity in truss-cored sandwich structures leads to an increase in out-of-plane compression strength. The flexural strength of fiber composite panels made with loofah plant fibers and wooden veneer as the skin layer increases with increasing adhesive quantity. The shape of the spew fillet and the amount of adhesive are key factors influencing the compression fatigue properties of truss-cored sandwich structures. Microcracking in sandwich panels made of polymeric composite materials is mainly observed at the adhesive/composite interface, and the thickness ratio of the facesheet to the core affects the microcrack lengths and flatwise strength.
