One-Stop Service For Lightweight Fiberglass Material

Thermoplastic skins or laminate sheets are composite sheets composed of Continuous Fiber Reinforced Thermoplastic (CFRT) unidirectional prepreg tapes, arranged in one or more combinations of fiber orientations, such as 0°, 45°, -45°, 90°, etc.

These sheets are manufactured through a process involving both hot and cold pressing.

Additionally, they can be integrated with high-performance core materials, including honeycomb sandwich panels, PET foams, polyurethane panels, among others, or can be combined with non-woven materials to create innovative sandwich composite panels

Wings of Tomorrow: Advancements in High-Temperature Thermoplastic Composites for Future Aircraft Wings

In the past, structural components for civil aircraft were typically manufactured using thermosetting epoxy resin based composite materials.

liquid epoxy resin

However, due to the primary shear load-bearing nature of wing ribs and the poor shear resistance of thermosetting composites, aluminum alloys had to be used as an alternative.

High-temperature thermoplastic resins include PEEK, PAEK, and PEKK.


To meet the demands for composite wings in the future “New A320” aircraft model, Airbus initiated a research and development project named “Wings of Tomorrow.”

The project involves over 100 components and corresponding manufacturing technologies, one of which is the fabrication of wing ribs using high-temperature thermoplastic composites.

The “New A320” wings will feature over 20 such ribs, with the largest rib measuring 2 meters in length and 1 meter in width, capable of bearing loads ranging from 1 to 50 tons.

This development work is undertaken by France’s Daher and the UK’s GKN, tasked with demonstrating the manufacturing of these ribs.

Daher utilizes unidirectional (UD) carbon fiber/low-melt polyaryletherketone (PAEK) tapes provided by Toray, while GKN employs APC carbon fiber/polyetherketoneketone (PEKK-FC) tapes from Solvay, based on the Novaspire PEKK-FC (FC) rapid crystallization formulation.

These thermoplastic aircraft wing ribs are manufactured by GKN Aerospace for Airbus’ “Wings of Tomorrow” demonstrator.

Daher and GKN use different thermoplastic base material PAEK tapes, melting at 305°C, while PEKK tapes melt at 340°C.

PAEK exhibits better flowability and can be processed at higher speeds compared to PEKK and PEEK, also offering lower costs.

PEKK, an emerging high-performance carbon fiber (CF)-reinforced composite material matrix, serves as a substitute for conventional PEEK.

It has a glass transition temperature of 162°C (323.6°F), a melting temperature of around 400°C, and a slow crystallization rate. PEKK contains two ketones and one ether, with ketone bonds imparting flexibility, thus enhancing the polymer’s flexibility.

Consequently, PEKK features higher glass transition and melting temperatures, along with high mechanical strength, high temperature resistance, fatigue resistance, and low flammability.

Additionally, PEKK demonstrates superior chemical fluid resistance compared to PEEK, with good dielectric stability and no emission of toxic smoke.

Different terephthalic acid/isophthalic acid content (T/I ratio) in PEKK results in varied crystallization kinetics and properties.

Higher crystallinity is crucial for performance, as it enhances material strength, stiffness, toughness, and chemical resistance.

PEKK exhibits excellent strength in longitudinal tension, longitudinal and transverse compression, and in-plane shear.

It also shows better interfacial shear strength (IFSS) compared to CF/PEEK, aiding its outstanding strength, as damage typically initiates at the fiber-matrix interface under in-plane loads.

Comparing predictions from various analytical models with experimental results favors CF/PEKK, assessing the impact of fiber-matrix adhesion on in-plane strength.

In cyclic shear tests, CF/PEKK demonstrates smoother stiffness reduction and lower shear plasticity until 5% shear strain, indicating higher damage resistance of the matrix.

Relative to CF/PEK, CF/PEKK exhibits excellent interlaminar shear strength (ILSS) and mode I fracture toughness (GIC-I), but similar mode II fracture toughness (GIC-II).

The high GIC results from the inherent ductile matrix and synergistic interaction with high IFSS, with ILSS closely related to IFSS. Overall, CF/PEKK offers a better combination of strength and toughness than CF/PEEK, achieving a compression after impact (CAI) strength of 337 MPa (48.9 ksi).

PEEK possesses excellent mechanical properties and a good strength-to-weight ratio, making it a viable alternative to certain metals.

In conclusion, there is a high likelihood that the wing ribs of the future “New A320” will be manufactured using carbon fiber/polyetherketoneketone (CF/PEKK) composite materials.
