摘要

Cork is a material of great value to the Portuguese economy. Unfortunately, its application is still restricted to the traditional areas, having yet to achieve its full potential field of application, especially in the agglomerate form. It is the purpose of this project the viability study of applying cork based material in aeronautical and aerospace applications as core materials in sandwich structures. It is intended to introduce such materials for its isolation properties (both thermal and acoustic), without significant performance loss when compared to the current used materials (namely Rohacell~R and honeycomb). It presents other advantages as well, such as, less energy waste in manufacturing and a better environmental integration, both in the transformation stage and in the end of life recycling stage. The objective of this study is to test different kinds of sandwich specimens, with carbon/epoxy faces, and cores of different kinds of cork agglomerates, in 3 and 4 point bending tests, using the standard test method ASTM C393, and its comparison with the results obtained with similar specimens using current material cores, for the same application. The results obtained show that there still exists significant room for improvement, in order for the cork agglomerates are able to compete with the leading materials. Calculations are presented to support these claims as well as a main avenue of investigation show by the failure modes of the cores, in order to improve the cork based cores competitiveness with the current core materials.
