‘Morphology Of Poly(ether Ether Ketone)/poly(ether Imide) Blends And Their Application As A Matrix For Carbon Fiber-reinforced Plastic – Nature’

Nature Apr 06, 2026

This study aims to develop composite materials that combine high chemical resistance with superior thermal stability by blending polyether ether ketone PEEK known for its chemical resistance and polyether imide PEI recognized for its heat resistance. The interfacial adhesion between carbon fibers CFs and PEEKPEI blends was systematically investigated from the perspective of the blend morphology. Compared with that between PEEK and CFs the interfacial shear strength IFSS between PEI and CFs was greater and the IFSS of the PEEKCF composites increased with increasing PEI content. At 508201wt PEI the IFSS became nearly equivalent to that of the PEICF composite. The distribution of PEI and PEEK near the CFs in the PEEKPEI 5050 matrix was examined using micro-Raman spectroscopy and scanning electron microscopy SEM. The results revealed a submicron-sized PEI-rich region near the CF surface. While PEI was completely soluble in chloroform the solubility of the PEEKPEI 5050 blend was limited to 13 indicating enhanced chemical resistance due to PEEK incorporation. The glass transition temperature Tg of PEEK also increased with the addition of PEI. These findings demonstrate that submicron-scale heterogeneous structures in PEEKPEI blends enhance thermal and chemical resistance and interfacial adhesion between the matrix and the CFs. The dispersion state of PEEK and PEI in carbon fiber-reinforced composites with a PEEKPEI blend matrix was investigated using micro-Raman spectroscopy and scanning electron microscopy. The results revealed a continuous coexistence on a submicron scale of crystalline PEEK amorphous PEEK compatible with PEI and isolated PEI domains near the carbon fiber surface. This submicron-scale morphology accounts for the enhancement of both the glass transition temperature of PEEK and the interfacial shear strength with carbon fiber upon blending PEI with PEEK.
