OCTOBER 2015 56 CompositesWorld reinforcement materials can be found through the following suppliers: A&P; Technology, Sigmatex, Oxeon, Texonic, Adfors, Textum, G. Angeloni, Composites Fabric of America (CFA), BGF, SAATI, Highland, Absecon, Axiom, Composites One, TexTech, TEAM Textiles, Vectorply, V2, Saertex, AEC, Carolina Narrow, Flotex and more. www.innegratech.com Janicki Industries (Sedro-Woolley, WA, US) will highlight its capabilities in tooling, prototyping and fabrication of parts for aerospace, marine, energy, architecture, military, space and transportation markets. Janicki has experience with many composites-related products, including syntactic putty; 71°C fberglass composites; 121°C carbon fber tools; 121°C carbon/fberglass hybrid molds; and 121°C Invar and steel molds. Of special note, says Janicki, are the following: • Carbon/JBXA layup molds that cure at 182°C and support more than 100 cycles. • Carbon/BMI layup molds that cure at 182°C and support more than 200 cycles. • Invar/steel layup molds that cure at 182°C and support more than 1,000 cycles. • Aluminum layup molds that cure at 121°C and support more than 250 cycles. www.janicki.com L&L; Products (Romeo, MI, US) will feature a range of room temperature- curing two-component fre, smoke, toxicity (FST)-compliant adhesives for simple assembly of composite parts. They're supplied in a two- component cartridge, and (as separate components) in pails or drums. One of the components contains an epoxy-based adhesive, while the other contains an amine-based curing agent. L&L; says its adhesives hold a high-strength bond and are designed to meet the stringent requirements of the aerospace industry. The company notes that a 12-second vertical burn is the minimum specifcation to meet FAA FAR 25 requirements; L&L;'s adhesives reportedly exceed the requirement by passing the most stringent of the tests at 60 seconds. All of the two-component adhesives have a 1:1 or 2:1 mix ratio, enabling easy working conditions, using standard applicator gun sizes. Typical gel times are 5-90 minutes, depending on the material used. All the company's two-component FST adhesives are REACH-compliant. Typical applications include bonding inserts to honeycomb panels, panel-to-panel bonding (ability to bond multi-material substrates), composite potting and fllet seals. www.llproducts.com Luna Innovations (Roanoke, VA, US) will present a paper on Thursday, Oct. 29 at 8:00 a.m., titled "In-Situ SHM of Composite- Overwrapped Pressure Vessels." It will demonstrate how Luna's High-Defnition Fiber Optic Sensing (HD-FOS) system is used to monitor distributed strain in composite-overwrapped pressure vessels (COPVs) throughout the manufacturing process, subsequent qualifcation testing and periodically during a pressure vessel's service life. Luna's ODiSI product platform uses HD-FOS technology to turn ordinary, unaltered, single-mode fber-optic cable into advanced strain or temperature sensors. Fiber-optic cables, when illuminated, have the equivalent of an optical fngerprint, which changes, in a predictable and repeatable way, in response to changes in strain and temperature. The fber sensor, coupled with Luna's advanced HD-FOS technology, replicates a virtually continuous line of strain gages or temperature sensors with mere millimeter spacing between sensing points. At 150 microns in diameter, the fber sensor also has the capability to be embedded within structures under test. For strain, this high-density sensing is suitable for measuring the non-linearity and high gradients associated with composite structures, as well as for fnite element analysis (FEA) model validation of designs with complex geometries or that use new advanced materials. www.lunainc.com See us at CAMX Booth # Y74 SHOW PREVIEW
