Moving parts - the bug's 9.1m/30-ft long claw, which swings down in a 90Int arc to threaten approaching riders, and its 6m/20-ft diameter head, subject to compound motion as it swivels - would be thin composite "skin" shell structures attached to articulating devices made from steel tubing and driven by computer-controlled actuating mechanisms. The creature's body would be anchored to a concrete base and steel support structure. However, Vipel K022-AAA-00 corrosion and fire retardant Bisphenol A epoxy vinyl ester resin from AOC LLC (Collierville, Tenn., U.S.A.) was finally accepted as a fire-safe matrix and adhesive. "Only fiberglass composites met all requirements," says Dore, although he notes that fire officials initially expressed reluctance to allow resin in the structure. ![]() Although a urethane foam substructure with a urethane hardcoat could have fulfilled artistic and weight requirements at low cost, Dore notes that the material lacks durability and cannot achieve the theme park's specified Class A fire rating, with Class I flame spread and smoke requirements (ASTM E-84 "Standard Test Method for Surface Burning Characteristics of Building Materials," ASTM International, W. The MIB icon presented Cinnabar with a multifaceted challenge: produce a lightweight structure that would not only meet requirements for durability and safety, but conform to exacting mechanical and artistic demands as well.
