Laser-based additive manufacturing of compositionally graded polyether ether ketone (PEEK) nano-composites
Abstract
The main objective of this proposed research is to lay the scientific foundation that will enable the additive manufacturing (AM) of multi-functional and compositionally graded high-temperature polymer composites. The discovery and efficient use of materials is the backbone for many of the U.S. Air Force s operations, ranging from structural components for aircrafts to propulsion systems and to satellites. Future materials need to be light yet strong, able to withstand extreme environments, such as high temperatures or radiation exposure, and possess multi-functionality, for example providing structural support along with electromagnetic interference (EMI) shielding or thermal management capabilities. A promising candidate to fulfill a wide range of these requirements is polyether ether ketone (PEEK), a semi-crystalline thermoplastic with a melting point of approximately equal to 340 degrees C, and its various composites. However, existing manufacturing techniques do not allow for the spatial control of the filler material - a prerequisite for the next generation of high-performance multi-functional composites.
