Hexcel will be showcasing its latest innovations in composites at CAMX 2018.
One of Hexcel’s newest technologies, HexAM additive manufacturing, combines high performance PEKK thermoplastics with carbon fibre to produce flight-ready 3D printed HexPEKK parts. Hexcel acquired this technology from Oxford Performance Materials in December 2017. HexPEKK structures are said to offer significant weight, cost and time-to-market reductions, replacing traditional cast or machined metallic parts in highly demanding aerospace, satellite and defence applications.
Hexcel will also present its HexShield thermal management system that provides high temperature resistance in aircraft engine nacelles. By inserting a thermally resistant material into honeycomb cells, Hexcel provides a core product with heat-shielding capabilities that allows for the potential reuse of material after a fire event.
Hexcel will also promote its Acousti-Cap broadband noise-reducing honeycomb that significantly improves acoustic absorption in aircraft engine nacelles. The acoustic treatment may be positioned at a consistent depth and resistance within the core, or it can be placed in a pattern of varying depths and/or resistances (Multi-Degrees of Freedom and 3 Degrees of Freedom), offering an acoustic liner that is precisely tuned to the engine operating conditions. These technologies have been tested at NASA on a full engine test rig and meet all 16 design conditions without trade-offs.
At the show, Hexcel will be launching its newest high modulus fibre, HexTow HM50, which boasts high modulus and high tensile strength, making it suitable for commercial and defence aircraft and engines.
The composites industry continues to examine new thermoplastic formulations to speed up production times while decreasing weight and lowering costs. Hexcel’s unsized HexTow carbon fibres provide excellent bonding interfacial properties with thermoplastic matrices. CAMX visitors will see HexTow carbon fibres being used in Hexcel’s own HexPEKK SLS additive manufactured parts, but also in a bike frame produced by Arevo, which was made using the FDM 3D printing process.
Hexcel will be promoting its latest PrimeTex woven carbon fabrics that decrease areal weight while providing a smooth, closed weave and uniform cosmetic appearance. PrimeTex fabrics are more uniform as the filaments in each tow are spread out creating a thinner and more closely woven fabric that provides better mechanicals and less porosity in a composite laminate.
Also on display will be Hexcel’s HiMax multiaxial reinforcements that are multiple layers of unidirectional fibres, with each ply placed in a different orientation or axis. These layers are then typically stitchbonded to form a fabric. HiMax reinforcements allow manufacturers to process multiple layers of unidirectional fibres in a single fabric. They offer solutions for many structural industrial applications such as automotive, marine, energy and more.
In the CAMX Awards area of the show, visitors will find an I-beam built from Hexcel’s HiTape and HiMax carbon reinforcements and its HexFlow infusion resin. The I-beam was manufactured in collaboration with TME using its new fully automated processing technology called C-RTM that requires no operator intervention. This structural part demonstrates a state-of-the art automated manufacturing solution for manufacturing next generation aircraft parts using high quality aerospace materials.
Hexcel will exhibit on Booth Y13 at CAMX 2018 on 16-18 October in Dallas, Texas, US.
