Huntsman Advanced Materials will highlight its line of resin systems, adhesives and syntactics that may be used to support the mass production of lighter weight, higher quality composite components to increase the fuel efficiency of automobiles and aircraft at CAMX 2018.

On display will be robust, lightweight auto wheels and engine hoods as well as flame-retardant aircraft galley panels and high-strength seat backs. Visitors to the booth will also be able to compare the densities and other properties of different Huntsman products on a new ‘interactive’ wall of cured material samples. At the Composites One Demo Zone, adjacent to the Huntsman exhibit, fibreglass leaf springs will be injected, cured and demoulded using a fast-curing ARALDITE liquid epoxy resin system through High Pressure Resin Transfer Moulding (HP-RTM) for rapid part production.

Developments in thermoset composite technologies for mass transportation applications will be the subject of a technical paper presented by Huntsman’s Klaus Ritter on Wednesday 17 October, 10:30-10:55 am in Room D220.

“Huntsman has worked with leading global automotive and aerospace manufacturers and suppliers for many years to develop advanced chemistries and material solutions to facilitate their processing and performance needs,” explains Derek Crofton, Vice President, Americas for Huntsman Advanced Materials. “Today, we are pleased to offer a comprehensive portfolio formulated to produce composite parts via a variety of fabricating processes that provide for mass production and yield components with remarkable strength, lightweight and performance characteristics.”

New materials being featured by Huntsman at CAMX include:

  • EPOCAST 1648 A/B epoxy syntactic adhesive is a low-density, thixotropic compound for reinforcing fasteners in honeycomb structures. It has been shown to meet FAA FST requirements and is qualified to the BMS 5-28, Type 18, Class 1 specification. The lightweight epoxy is meter/mix extrudable for easy application. It sets quickly and features good compressive and tensile lap shear strengths.
  • ARALDITE 2085 methyl methacrylate structural adhesive is a two-component, room-temperature curing material for rapid assembly of substrates including plastics, composites and metals. It features a convenient 1:1 parts by volume mix ratio, has a working time of 2-3 minutes and attains handling strength after 7 minutes at room temperature. Once cured, the adhesive produces joints with high peel strength and a service temperature of up to 212°F (100°C).
  • ARALDITE LY 3585/ARADUR® 3831 epoxy resin system is a two-part product with an extended pot life of 100-120 minutes at room temperature. (A shorter, <60 minute pot life can be obtained by using ARADUR 3834.) The epoxy material is designed for mass production of thick composite parts via Low Pressure Resin Transfer Moulding (LP-RTM), HP-RTM and wet compression moulding. Cured components feature excellent mechanical characteristics and have been shown to withstand long-term dynamic loading even under severe hot/wet conditions.
  • ARALDITE LY 1560/Aradur 917/Accelerator DY 079 hot-curing epoxy resin system is a toughened material for producing high-performance composite parts such as automotive wheels. Depending upon the amount of accelerator used, the system has a gel time from 7-20 minutes and cure time from 20-40 minutes at 248°F (120°C) + 2 hours at 374°F (190°C). The epoxy offers a high glass transition temperature as well as good fracture toughness and tensile strength.

Huntsman will exhibit on Booth Y27 at CAMX 2018, on 16-18 October in Dallas, Texas, US.
