This paper presents the mechanical properties for sandwich core strips with a 60% sandarac combination core and 40% Resoltech 1050 epoxy resin with 1055 hardener, and the upper and lower layers reinforced with cotton, silk and linen fabric, and the matrix is a combination of 60% dammar resin and 40% Resoltech 1050 epoxy resin with 1055 hardener. For these materials, there is determined: static mechanical properties from tensile stress (Young elastic modulus, yield strength, breaking strength) and chemical composition by energy dispersive spectroscopy analysis with an scanning electron microscope. It is observed that the dammar resin, in all the cases, has increased mechanical characteristics compared to sandarac. Also, the samples reinforced with cotton show better mechanical properties compared to the ones reinforced with flax and silk.
