Monotonic Load and Creep Properties of Carbon Nanotube Sheets

Abstract

Carbon nanotube sheets are a new and promising material with properties such as high tensile strength and low density that are ideal for future applications in the aerospace industry. Before those materials can be implemented in future air and spacecraft, their mechanical properties must be fully understood. Tensile and creep tests are the first and necessary steps to being able to better understand the properties and failure mechanics of any new material. This research is to understand the long term effects and performance of CNT sheets under tensile load, specifically through tensile tests, creep, and tensile tests after exposure in a space like environment. The data was used to create stress vs strain plots in order to mathematically quantify the tensile and creep behavior of the CNT sheets. The sheets were also exposed to Ultra Violet radiation in order to understand how the strength properties changes under relevant space like conditions.
