CAMX 2017 preview: Scott Bader
Appears in Print as: 'Structural Adhesives: Shorter Fixture Times '
Scott Bader Company Ltd. (Wollaston, UK) is promoting the full range of its high-performance resins, gelcoats, bonding pastes and structural adhesives. Special focus during the exhibition is on the new range of Crestabond primer-less MMA adhesives, used for mid- and high-volume assembly by OEMs and Tier 1 and 2 manufacturing companies for bonding a variety of substrates in structural applications, with little if any need for surface preparation or a primer. All Crestabond products are toughened, two-component methacrylate adhesives, developed for bonding unsaturated polyesters, vinyl esters and epoxy glass and carbon fiber FRP composite parts, as well as many other substrates used for fabrication, such as wood, balsa and synthetic foam cores, engineering thermoplastics and metals.
Scott Bader is also featuring the Crestapol range of high-performance urethane acrylate resins, with particular emphasis on the fire-retardant (FR) properties of filled Crestapol resins and Crystic FR gelcoats and intumescent topcoats. Crestapol resins can be processed by open molding, infusion, resin transfer molding (RTM) and pultrusion. The fire-retardant products available, when used in specified FR laminate systems, can meet many of the most stringent fire, smoke and toxicity (FST) standards needed for FRP parts used in buildings, rail, metro and other mass transportation applications, including subterranean environments.
This FST product focus on the booth is linked to a technical paper being given at CAMX by Steven Brown, polymer development manager at Scott Bader, titled “A Review of Recent Changes to European Fire, Smoke & Toxic Fume Composites Standards, Successful Case Studies and Potential Applications and Crossover into the American Composites Market.” The presentation is Tuesday, Sept. 12, 2:30-3:15 pm, room W207A.
For markets such as automotive, transportation and aerospace, Scott Bader is emphasizing Crestapol 1260 infusion resin as an alternative to epoxy. To illustrate the high-performance capabilities of Crestapol 1260, visitors to the booth can see the composite fuselage top section of a newly designed light aircraft made by Jeff Kerlo called X-Project, manufactured with a laminate design comprising Crystic 15PA gelcoat, Crestapol 1260 infusion resin, with TeXtreme thin-ply carbon fiber fabric, PVC foam core and Innegra HMPP high-performance fiber reinforcement materials, supplied for this new fuselage development project by contributors DIAB, T.E.A.M. Inc., and Soller Composites. Booth N16.
Designers envision aircraft components that do more than bear structural loads, but must first confront great complexities to actualize greater functional efficiency.
Disruptive designs for composites operation in 1093°C zones.
Hand layup has a long history in aerospace composites fabrication, but it's not well suited for automotive composites manufacturing, where volumes are much higher. But the discrete placement of fiber reinforcements still has value. Research is pointing toward automated hand layup that might help this process bridge the aerospace-to-automotive divide.
