construction COMPOSITES WATCH New composite reinforcing grid enables thinner concrete façade panels Frekote® leaves other mold release products in its wake Composite manufacturers depend on Frekote® mold release agents because they: • allow multiple releases per application • result in a clean, hi-gloss finish • are fast curing • reduce downtime/ increase productivity • decrease rejection rates/ improve quality • lower manufacturing costs/boost profitability ForexceptionalperformanceeverytimechooseFrekote® moldreleaseproductssuchasthese: 710-LV™ a solvent-based mold release agent with low VOCs, high slip with non-contaminating transfer, no mold buildup. FMS-100™ a streak-free, solvent-based mold release sealer that offers ease of application, high gloss finish and fast cure. Eliminates porosity/micro porosity, and even seals "green" molds and repaired areas. compositesworld.com AquALine®C-600™ a water-based emulsion that sets the standard for water-based release agents.

All rights reserved. 10618 (6/13) Source | SGL A 3-D carbon fber reinforcement recently developed by SGL Group - Te Carbon Co. (Wiesbaden, Germany) and V. FRAAS Solutions in Textile GmbH (Helmbrechts, Germany) has recently proven its worth. SGL reported on Aug. 16 that it is possible to produce concrete façade panels only 26 mm/1.02 inches thick using a "carbon grid" as internal reinforcement. Te grid consists of two plies of carbon fber scrim spaced 12 mm/0.47 inch apart that are connected by compression-resistant pile threads. A steelreinforced facade panel of similar size reportedly has a minimum thickness of 100 mm/3.94 inches — the extra thickness is necessary to prevent corrosion of the steel due to water ingress by way of cracks in the concrete. Te thin facade panels were installed on a new factory for Alphabeton AG in Buron, Switzerland, an innovative specialist in concrete products manufactured from high-performance and ultrahigh-performance concrete (UHPC). A ventilated façade "curtain wall" was installed on the building, with a total area of 450m2/4,844 f². Te wall comprises 350 panels, each measuring 865 by 1,620 mm (34 by 63.8 inches), with a thickness of 26 mm/1.02 inches. Te building, appropriately, houses a precast concrete element production line. "We were looking for a solution that would enable us to produce thin concrete façade panels in large dimensions," says Alphabeton's Hans-Peter Felder, who is responsible for R&D.; "Te new 3-D carbon fber grids impressed us with their light weight and corrosion resistance and were easy and convenient to process." Peter Weber, VP of sales and marketing for SGL's Carbon Fibers & Composite Materials business unit, adds, "In this application, we particularly exploit the corrosion resistance of our carbon fbers. Tanks to this advantageous property, we can dispense with the thick concrete covering obligatory with steel-reinforced concrete to prevent rust and produce thin concrete elements." V. FRAAS has developed a production plant in which the new 3-D textile reinforcement is manufactured with SGL's SIGRAFIL C carbon fbers, in large dimensions. Te structural grids are also being used in the repair and renovation sector and in bridges and buildings, says V. FRAAS.
