WEDNESDAY, DECEMBER 13, 2017 / ORLANDO, FLORIDA CAM X 2017 8 SHOWDAILY NEW TECHNOLOGY PET-Based Structural Foam Core Armacell Benelux SA (Thimister-Clermont, Belgium) is showcasing its ArmaFORM PET product family. ArmaFORM PET Core is a PET-based (polyethylene terephthalate) structural foam core offered in densities of 4.1-20.0 lb/ft 3 and thicknesses of 0.20-0.49 inch. ArmaFORM PET Foil is a thin, flexible PET sheet available in various thicknesses up to 0.02 inch, in densities of 4.4-18.7 lb/ft 3 and tailor-made formula- tions in terms of stiffness and fire resistance. ArmaFORM PET MultiCore combines different densities in one foam core to improve impact and point load resistance. It offers what is said to be a unique combination of properties, including better strength-to-weight ratio, higher impact and point load resistance. The use of higher density layers allows for superior screw retention without additional reinforcement. ArmaFORM PET Beads are PET-based particle foams for the manufacture of ready-to-use 3D shaped parts on an industrial scale. PET Beads combine the high mechanical properties of structural foam cores with the advantages of particle foams and offer lightweight and strong 3D foam parts that are producible in any shape.

(Bristol, UK) is demonstrating its integrated material testing system, Universal Video Extensometer (UVX), designed for ease of use and fast throughput. UVX meets most standards-based material testing and is adaptable to batch testing. It is designed to integrate with all leading manufacturers' test machines and is characterized as a cost-ef- fective alternative to strain-gauging coupons. In addition, measurement data is captured by pre-calibrated extensometer modules that are specified by gage length and percentage strain. Parameters associated with each module are pre-set, eliminating the need for the test technician or materials engineer to under- stand optics or worry about focus and camera settings. The 200- and 250-series modules allow precision measurements down to 0.01% strain. These modules are suited to determining modulus, Poisson's ratio, and other low-strain material properties, such as R and N values, for almost all materials, including composites, metals, plastics, rubbers and ceramics.

Structural Adhesives: Shorter Fixture Times Scott Bader North America (Stow, Ohio) is featuring two new Crestomer grades recently added to its structural adhesives range: Crestomer Advantage 10 in 380-ml cartridges, with a 50% shorter fixture time of only 70 minutes (compared with Advantage 30); and Crestomer 1150PA, available in 25-kg pails and 200-kg drums for use with dispensing equipment, also with a 50% shorter fixture time of 5 hours compared with Crestomer 1152PA, which is a long-established grade with Lloyds, DNV and RINA marine approvals. Both new grades are primarily aimed at structurally bonding smaller-sized composite components and improving productivity. All Crestomer products are urethane acrylate-based structural adhesives in a styrene monomer. Scott Bader notes that they were originally developed for bonding GRP and marine ply substrates, but that with suitable surface preparation, they also can be used to bond aluminum and stainless steel parts. All grades are highly thixotropic and, therefore, do not sag during application on vertical surfaces, and they exhibit good gap-filling capabilities. Scott Bader North America, Booth N16. Nonwovens for Advanced Composites Technical Fibre Products Inc. (TFP, Schenectady, New York) is exhibiting new nonwoven fabrics. The first is a novel PTFE nonwoven that acts as a release material and breather fabric and offers a combination of hydrophobic and non-stick prop- erties. Also new for 2017 is a range of lightweight nonwovens with increased flexibility, smoothness and fiber volume. These new materials, designed for advanced composites, have been compressed to deliver a higher density, reduced thickness and smaller pore structure for a given areal weight. They have been designed to give improved conformability when working with complex mold shapes and, due to the thinner structure, increase the achievable volume fraction. The veil is available in a range of fiber types and areal weights. TFP is introducing a nano-functionalized nonwoven, created on TFP's commercial nano- coating line in Schenectady. The incorporation of nanomaterials, such as carbon nanotubes or nanofibers, into or onto a nonwoven, can provide multiple benefits including enhance- ment of surface conductivity, EMI shielding, thermal management and structural properties.
