YLA (Benicia, Calif.) has developed Xponent, a new family of resins for unmanned aerial, underwater and surface vehicles (UAVs, UUVs and USVs, respectively), targeting lightweight structural, mechanical and airfoil components. The material is available for use with unidirectional and woven prepregs reinforced with virtually any available fiber, as well as towpreg, plus tackified fabric for resin transfer molding (RTM) and tooling. The manufacturer has used the material in a variety of aircraft, UAV and marine applications: prepregs and adhesives with 200°to 350°(93°to 177°C-) cure epoxies; high-temperature bismaleimide (BMI) and polyimide systems with 350°F to 700°F (177°C to 371°C) cure; toughened polycyanate esters matched to customer-specific needs, with 265°F to 550°F (130°C to 260°C) cure. Also new: Microply syntactic foams and films for tuned-dielectric and low-observable structures.
