In the aerospace field, Carbon/Cork composites have been used for rocket propulsion systems as a light weight structural component with a high bending stiffness and high thermal insulation properties. For the fabrication of a carbon composite with a heat insulation cork part, the bonding properties between them are very important to determine the service life of the Carbon/Cork composite structure. In this study, the changes in the interfacial adhesion and mechanical properties of Carbon/Cork composites under accelerated aging conditions were investigated. The accelerated aging experiments were performed with different temperatures and humidity conditions. The properties of the aged Carbon/Cork composites were evaluated mainly with the interfacial strength. Finally, the lifetime prediction of the Carbon/Cork composites was performed with the long-term property data under accelerated conditions.

The purpose of this experimental study is to develop the waterborne silicon acrylic surface finishing material of parking lots. Adhesion strength experiment was conducted in order to enhance performance of the finishing material by adopting modified polyamide resin. The results qualified the standard regarding bond strength which is prescribed in KS F 4937. They are confirmed that the strength tend to increase as the amount of polyamide increased and could be an optimum surface finishing material applicable for parking lot floor.

The purpose of this experimental study is to carry out test for the surface finishing material of parking lot using Cross-linking agent(Zinc Oxide). The specimen was fabricated by KS F 4937, Cross-linking agent 2%, 3%, 4% is mixed in water soluble acrylic resin. As a result, bond strength of surface finishing material using Zinc oxide 4% was confirmed to be superior than surface finishing material using ordinary Acrylic resin.
