Hexcel’s newest technologies at CAMX 2018

Hexcel, a leading advanced composites company, will be exhibiting at the CAMX conference on in Dallas, TX, next week, to promote its latest technologies and innovations in composites.

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 unique heat-shielding capabilities that allows for the potential re-use of material after a fire event,” the company explains.

Hexcel will also promote its Acousti-Cap broadband noise-reducing honeycomb that is designed to improve 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, 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 tradeoffs,” the manufacturer adds.

HexTow HM50

At the show, Hexcel will be launching its newest high modulus fibre, HexTow HM50, which boasts high modulus and high tensile strength, which make it ideal 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 are said to provide excellent bonding interfacial properties with thermoplastic matrices. “Not only will visitors 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,” the company reports.

Hexcel will be promoting its latest PrimeTex woven carbon fabrics that decrease areal weight while providing a smooth, closed weave and uniform cosmetic appearance.

HiMax multiaxial reinforcements

Also on display will be Hexcel’s HiMax multiaxial reinforcements, also known as non-crimp fabrics (NCF), 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.

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 their 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.
