Survey of Poly-Ether-Ether-Ketone and Its Advanced Composites

摘要

The suitability of poly (ether-ether-ketone) PEEK for aircraft structures was reviewed. Its major advantages compared to present epoxy matrix systems are: increased toughness; better impact resistance; greater ease of repair; less hygroscopic; infinite shelf-life; some metal forming operations are transferable to thermoplastic forming; and quality of material may be better in terms of less batch-to-batch variation. However, in processing thermoplastics one can encounter; higher pressures and temperatures; and difficulties with fiber-wet-out at the higher molecular weights and consequently higher void contents.
