Abstract
From the desire to produce environmentally friendly composites, sandwich composites with a matrix made of a Dammar-based hybrid resin, a core of chopped corn cobs, and faces made of natural fabrics were cast and researched in terms of their mechanical properties. The low production cost and the mechanical characteristic values obtained for these sandwich composites have shown that they represent an alternative to MDF, or PAL (Medium Density Fiberboard, or Chipboard). As an application, two elements of a bathroom cabinet were made. The cabinet was exposed to a high-humidity environment, and it was found that the humidity level did not cause any changes in shape or appearance of the elements made from the sandwich composite.
