Fiber/Matrix Adhesion in Graphite/PEKK Composites

Journal of Thermoplastic Composite Materials, 1992
Experiments with poly ether ketone ketone (PEKK) resin and AS-4, IM-7, and G30-500 fibers showed excellent correlation between resin/fiber contact angle and composite transverse flexural strength as measures of resin/fiber interfacial strength. Both tests indicate the strongest interface for G30-500/PEKK followed by IM-7/PEKK and AS-4/PEKK.

Depositing Aluminum onto PEKK Composites by Cold Spray

Journal of Thermal Spray Technology, 2020
High-pressure cold spray (HP-CS) was used to deposit aluminum onto polyetherketoneketone (PEKK) composite substrates. Aluminum powders were sprayed using N2 and He carrier gas and a bond layer (BL) of commercial-purity Al (CP Al). Dense 7075 and CP Al deposits were achieved via combinations of BL-N2, 7075/BL-N2, and 7075/BL-He. Cold spray using 7075 Al

Microporous Coatings of PEKK/SN Composites Integration with PEKK Exhibiting Antibacterial and Osteogenic Activity, and Promotion of Osseointegration for Bone Substitutes

ACS Biomaterials Science & Engineering, 2019
To improve the antibacterial and osteogenic activities of poly(etherketoneketone) (PEKK), concentrated sulfuric acid (H2SO4) suspension with silicon nitride (SN) microparticle was utilized to modify PEKK surface. Through sulfonation reaction, microporous coatings of PEKK/SN composites were created on PEKK surface, which were integrated with PEKK ...

PTCa/PEKK piezo-composites for acoustic emission detection

Sensors and Actuators A: Physical, 2002
Abstract Piezoelectric ceramic/polymer composites with mixed connectivity combine the high values of piezoelectric coefficients of the ferroelectric ceramics and the formability and flexibility of the polymer, making them suitable for in situ acoustic emission (AE) sensors.

High‐temperature steam‐treatment of PBI, PEKK, and a PEKK‐PBI Blend: A solid‐state NMR and IR spectroscopic study

Journal of Applied Polymer Science, 2012
AbstractBlends of polyaryletherketones (PAEK) with polybenzimidazole (PBI) are of commercial interest due to their improved upper service temperatures and wear properties when compared with the PAEK analogs examined to date. The retention of properties of the PBI component generally thought to be disadvantageous in more thermally or chemically ...

Isothermal crystallization kinetic modeling of poly(etherketoneketone) (PEKK)

AIP Conference Proceedings, 2016
Isothermal melt and cold crystallization kinetics of poly(etherketoneketone) (PEKK) have been investigated by differential scanning calorimetry. A modified Avrami model has been used to describe the two-stage crystallization of PEKK. The primary crystallization stage is assumed to be a two dimensional nucleation growth with an Avrami exponent of 2 ...
