Composite materials are finding new applications in many situations and are better than the conventional materials because of their excellent properties. In the present investigation, aluminium sandwich composite laminates are fabricated and their tensile property is evaluated. The structure of the composites and their fractured surface are studied by using Scanning Electron Microscope. The analysis of the experimental results indicated that the incorporation of aluminium stack as sandwich improves the properties and can be used as a structural material for construction.

Sandwich Materials

The paper presents aspects observed during classic three-point test bending of various sandwich materials. These aspects outline the need to spare special attention to such test, in connection with the particular material and service life conditions it will endorse. Such special care is needed in conditions of scarcity of dedicated standards and some evasive formulations in the existing ones.

The Difference

In this paper, an experimental study was conducted to determine the efficiency of repair methods for sandwich composites used as hull materials in leisure ships. The method was applied to external, scarf, and step patch repairs using an epoxy bond. The load was described in terms of the hogging and sagging moments applied to the hull by waves. Static and fatigue tests were performed to derive the recovery rate of repaired specimens. The experimental results indicated that the recovery rate of specimens with the scarf patch was the highest at 91.80% when the hogging moment was applied. However, the difference in the recovery rate between hogging and sagging moments was the lowest for specimens with the step patch, and the recovery rate was high at 89.96% and 85.15%, respectively.
