“…PEEK is indeed one of such best candidates, due to its high melting point, good biocompatibility, high mechanical properties and chemical resistance [5][6][7]. However, due to the high melting temperature, it was not possible to process PEEK with standard LS systems with operating temperature only up to 200°C until the High Temperature Laser Sintering (HT-LS) system, EOSINT P800 was introduced to the market.…”

Composites have the potential to enhance the mechanical properties of components fabricated by additive manufacturing; however, the bottleneck is the limited number of polymeric composite powders available for this manufacturing process. This paper describes a generically new method to create composite powders that are suitable for High Temperature Laser Sintering (HT-LS). C-coated Inorganic Fullerene-like WS 2 (IF-WS 2 ) nanoparticles and graphene nanoplatelets (GNPs) have been chosen to demonstrate their incorporation into a high performance polymer matrix: Poly Ether Ether Ketone (PEEK). The morphological and physical property investigations have confirmed that the resulting composite powders exhibit the desired particle morphology, size, distribution and flowability for HT-LS applications. Further preliminary sintering results have demonstrated that they are comparable to the currently available commercial grade of PEEK powder HT-LS applications in terms of powder packing properties and flow ability. The new strategy reported here brings in great potential for the additive layer manufacturing of high performance polymeric composite components with improved mechanical and added functionalities by choosing the proper matrix and filler combination.

“…These methods utilize polymers, surfactants, acids, or a combination of several different materials to disperse carbon nano-tubes [12][13][14]. Several of these methods tend to utilize hazardous materials and lengthy procedures to produce the desired result, while others require less dangerous materials with shorter durations to produce a similar result [5,6,[12][13][14][15][16][17][18][19][20][21][22][23][24].…”

The idea of adding reinforcing materials, or fillers, to polymers has been around for many decades. The reason for the creation of polymer composite materials came about due of the need for materials with specific properties for specific applications. For example, composite materials are unique in their ability to allow brittle and ductile materials to become softer and stronger. It is expected that good tribological properties can be obtained for polymers filled with nano-scale fillers. A soft plastic can become harder and stronger by the addition of a light weight high stiffness material. In the present work, the effect of adding different percentages of carbon nano-particulates to polystyrene (PS) on the mechanical properties of nano-composites produced was investigated. Based on the experimental observations, it was found that as the percentage of the carbon nano-particulates (CNP S ) increased hardness increased and consequently friction coefficient remarkably decreased.

“…It exhibits excellent resistance to radiations, and a V-0 flammability rating down to 1.45 mm thickness with low smoke and toxic gas emission. Therefore, it is used as a matrix for the preparation of high performance polymer composites using various reinforcing fillers [1][2][3][4][5][6][7][8].…”
