SUMMARY:

Environmental concerns regarding discarded polymers and petrochemical-based materials are continually increasing, driving the industry towards sustainable alternative solutions. This work compares the performance of two different castor-oil-biobased adhesives and a petrochemical-based epoxy on sandwich panels with galvanised steel skins and a bottle cap core. The galvanised steel plates are sanded to identify the effects of the surface roughness on the adhesive performance. The impact of small gaps among the bottle caps with hexagonal packing is also investigated concerning the mechanical properties of the panels. Three point bending testing is conducted following ASTM C393. Four mechanical properties—flexural modulus, ultimate mean stress, maximum load, and modulus of resilience—are compared. The typical force-displacement curves obtained across the three-point bending tests exhibit promising results for one of the biobased resins. In contrast, the gaps included between the bottle caps result in decreased mechanical properties.
