Sekisui Chemicals (Tokyo, Japan) is a high performance plastics company with 190 locations in 20 countries. Sekisui is showcasing several of its company’s divisions at CAMX, including Sekisui Aerospace, Sekisui R&D, Sekisui Chemical (Performance Materials Division) and Sekisui Polymatech, and the various technologies and services offered by each.
Sekisui Chemical R&D develops next-generation materials that contribute to the environment, particularly focusing on carbon fiber reinforced polymer thermoplastic (CFRTP) impregnation technology based on the company’s original spreading method . This technology would have allowed the impregnation of high surface mass fibers and thermoplastic parts made with a high viscosity resin. This division presents functional prepregs and filament materials (high heat resistant nylon, etc.) for additive manufacturing (AM) based on key technologies.
Sekisui Chemical (Performance Materials Division) creates high performance plastics, urban infrastructure and environmental products, residential housing modules and chemical solutions for industrial fields, transport equipment, electronics and health. This R&D division introduces HFL sheet, a composite of thermoplastic resin fibers with cover material x flame protection x thermal insulation that can apparently withstand the explosion of a lithium-ion battery ignition.
Sekisui Polymatech products cover thermal management and EMI solutions, sealed and complex molding, vibration and acoustic shock damping, elastomeric connectors, input device solutions and portable devices.
For more than 33 years, Sekisui Aerospace would have pioneered the design and manufacture of aircraft components. Product focus encompasses interiors, engines, structures, unmanned aerial vehicles (UAVs), environmental control system (ECS) ducts, primary and secondary structures in thermosets and thermoplastics – including ultra-lightweight certified structural components – and complex high-volume systems for commercial applications. , defense and general aviation.
A breakdown of the products and technologies in this list is as follows:
- Primary works: Drone structures, fuselage assembly, empennage, nose assembly, avionics enclosure, splice straps, wings, wing-body fairings, wing components, stabilizer tip cap.
- Secondary works: Storage bin supports, shims and drilling coupons, composite panel assemblies, evacuation slide panels, floor panels.
- Interior structures: Seat furniture, galleys, cockpit doors, life raft stowage, toilets, luggage bins, crew rest pods, video control cabinets, side walls, cargo liners, cupboards and dividers, hulls crushed core seat.
- Environmental control systems: Custom, oven-cured composite products made from carbon, fiberglass and Kevlar prepregs.
- Passenger service units.
- Auxiliary power unit intakes and exhaust systems.
- Engines and nacelles: Chinas and strakes, gearboxes and thrust doors, brackets, clips and brackets, fan blade spacers, outer guide vanes, acoustic panels and high temperature bleed air ducts, forward support structure and track fairings thrust reverser.
- QForge, a proprietary process for compression molding thermoplastics using chopped carbon and other fibers for custom fabrication. Parts are structurally optimized, meeting and/or exceeding metal parts, resulting in over 40% weight reduction at the same or lower cost.
- Continuous Compression Molding (CCM) produces preconsolidated thermoplastic laminates 0.02 to 0.40″ thick and 24″ wide with custom ply orientations, automated ply cutting, alignment and welding. The quality of the laminate is verified by non-destructive inspection (NDI).
- Automated Press Cell (APC), a high throughput automated stamping forming cell, converting blanks producing continuous fiber structures of varying complexity.
- Automation of robots and cobots, including more than 50 moving lines to achieve flow and tact time.
A Critical Market Sector: Downhole Composites in Oil & Gas
Tremendous secrecy and non-disclosure has kept this profitable composite application out of the spotlight, as it enabled the current shale oil energy boom.
Recycling composites becomes a necessity
Boeing and Airbus each generate up to 1 million pounds of cured and uncured carbon fiber prepreg waste each year from 787 and A350 XWB production. If you include the entire supply chain for these aircraft, the total is closer to £4m a year. And with the automotive industry poised to consume (and waste) more carbon fiber than ever before, recycling composite materials has become an absolute necessity. The technology is there, but the markets are not. Still.
