The new composites qualification service can configure a GRANTA MI:Composites software package for a user organization’s specific needs. For example, Granta
experts will quickly set up data import tools so that they automatically process data from a specific test machine. All of the data generated during qualification,

and its inter-relationships, are captured, enabling full traceability, and future re-use. Granta Design; www.grantadesign.com
DolphiTech says that its DolphiCam Ultrasound NDT Camera System has received new functionality for drilled hole inspections on carbon fiber reinforced plastic (CFRP) laminates. ‘We have made important breakthroughs on the DolphiCam system in the inspection of drilled hole flaking and delamination,’ said Eskil Skoglund, head of development at DolphiTech. ‘The improvements include

functionality for better detectability as well as technical solutions for easy use and interpretation of results. We are now comfortably able to detect flaking and delamination along the drilled hole as small as 2 mm (0.08 inch), and only 1–2 plies from the laminate front and back walls.’ The new functions will be made available as a software upgrade to existing customers.

SGL develops new TowPregs SGL Group has launched a range of preimpregnated TowPregs, fiber bundles from carbon or glass fibers suitable for challenging winding and lay-up processes. The SIGRAPREG TowPregs have good mechanical properties and permit much more uniform lay-up, the company says. TowPregs can also improve health and safety and environmental protection.

SGL Group has also developed continuous carbon fiber tow for fiber-reinforced thermoplastics and SIGRAPREG prepreg with a newly developed transparent resin system, suitable for visible components in the automotive and other sectors. The use of this prepreg in combination with the SIGRATEX design fabric produces components with improved high surface quality and appearance. SGL Group; www.sglgroup.com
Cytec introduces new fabric tooling prepreg Cytec Industries Inc has launched BMI and epoxy versions of DForm Fabric Tooling Prepreg. DForm deformable composite system combines short fiber conformability with the handling and laminate characteristics of a conventional long fiber composite. Its
deformation characteristics are achieved through selective fiber slitting of a fabric prepreg, and it does not require detailed laminating. This prepreg system flows under pressure, replicating precise details, retaining thickness and fiber orientation and producing a good surface finish.
DForm Fabric Tooling Prepreg is available as formatted multi-ply tiles of standard fabric tooling prepreg to which Cytec disruptive DForm technology has been applied. Cytec Industries Inc; www.cytec.com
Owens Corning launches new products at JEC Owens Corning has launched a number of new glass fiber materials at JEC. These include the PulStrand 4100 roving, which has improved processing qualities, strength, and fatigue resistance in a multicompatible product for polyester, vinyl ester, epoxy, and polyurethane resin systems. This material has the potential to provide faster line speeds while reducing downtime,
scrap, and labor, and improves the modulus and durability of the pultruded profiles for a variety of high-performance markets. The sizing chemistry of the PulStrand 4100 product ensures improved resin-toglass adhesion and faster wet-out by more than 50% when compared to existing products. Further tests have also shown a reduction of fuzz formation of up to 92%, less
part bowing, and deformation and improved humidity resistance. In addition, the sizing also allows for increased glass content (higher modulus) and helps to improve the flexural, shear, and compressive strength of composite products. The PulStrand 4100 product covers a wide tex range (600–9600) and can be
