CAMX 2018 11 TUESDAY | October 16, 2018 Ovens span cure needs LEWCO is exhibiting its line of industrial ovens, including a full range of batch ovens, conveyor ovens, drum ovens, tote ovens, hot boxes, drum heating tunnels, large field-assembled ovens and high-temperature furnaces. The company also emphasizes its capability to engineer and manufacture custom equipment made to customer specifications. LEWCO, Booth H62 Preforms, 3D-woven joints and thermal protection systems the sub-com- ponents being joined. Bally Ribbon Mills' ability to vary yarn types, density, thickness and width, as well as resin type, enables the company to create fully customizable TPS to fit specific mission or application needs. Notable applications include heatshields and aircraft engine parts. Bally Ribbon Mills, Booth S49 Bally Ribbon Mills (Bally, PA, US) is featuring its line of specialty fabrics and preforms, including 3D-woven joints, thermal protection systems (TPS) and other 3D structures. Bally Ribbon Mills uses 3D continuous weaving to create new joint structures and improve existing joints. 3D woven joints are available in "Pi," double "T," "H" and other complex net shapes. Bally Ribbon Mills says that because of the nature of the 3D weave, strength and support is translated in all three dimensions, thus enabling the join to reinforce the strength along the load paths of the substructures being joined together. These 3D woven shapes for joining can be tailored to suit the architecture of the structure itself, as well as Ultra-low density syntactic form for core splicing Magnolia Advanced Materials (Atlanta, GA, US) is exhibiting Magnolia 7035, a new, ultra-low density syntactic foam for core splice applications. Magnolia 7035 is a two-part epoxy paste that can be applied between the honeycomb sheets in the amount needed to bridge the gap. Magnolia 7035 cures at room temperature and can then be processed through a typical cure cycle for the face sheets. The pot life of the mixed resin is 30 minutes, and it develops handling strength in less than 2 hours. The cured density of Magnolia 7035 is compa- rable to foaming adhesives, but offers favorable mechanical properties up to 250°F. Because it is a syntactic, it is a closed cell foam and this will give the adhesive better environmental resistance than the open cell foaming type. Magnolia notes that typically, splicing honeycomb sandwich panels requires the use of foaming adhesives, which expand during a heat cure to bond the honeycomb sheets. This process can require cutting strips of core slice sheets to size and then placing the strips between the sheets of honeycomb. During the cure, the foam expands to fill the gap and bond the adjacent sheets together. If the cut edge is irregular, then the space may be too large in some areas for the foam to fill and the resulting gaps will compromise the properties of the sandwich panel. Magnolia contends that Magnolia 7035 eliminates these problems while producing a lighter, stronger and more environmentally stable panel. Magnolia Advanced Materials, Booth BB13 NEW TECHNOLOGY
