Denver's Hybrid Bus Has Thermoformed Body and Seats.Denver has 10 new low-polluting buses with all-thermoformed body and roof panels and interior seats. Designed by local firm TransTeq, Inc., the 116-passenger buses use a hybrid combination of natural gas and electric battery power. The plastic used is Kydex acrylic/PVC sheet from Kleerdex of Aiken, S.C. It was chosen for its smooth finish, easy formability, resistance to road salt and cleaning fluids, ability withstand 110 F summer heat, and impact resistance at winter chills Track listing Disc one
Kydex 103 sheet for the body panels is heated in a 9 x 16 ft forming oven. Roof panels are produced by drape drape v. To cover, dress, or hang with or as if with cloth in loose folds. n. A cloth arranged over a patient's body during an examination or treatment or during surgery, designed to provide a sterile field around the area. forming the curved sides and then welding welding, process for joining separate pieces of metal in a continuous metallic bond. Cold-pressure welding is accomplished by the application of high pressure at room temperature; forge welding (forging) is done by means of hammering, with the addition of heat. them to flat sheet stock. The front and rear panels would normally be a thermoset A polymer-based liquid or powder that becomes solid when heated, placed under pressure, treated with a chemical or via radiation. The curing process creates a chemical bond that, unlike a thermoplastic, prevents the material from being remelted. See thermoplastic. fiberglass fiberglass, thread made from glass. It is made by forcing molten glass through a kind of sieve, thereby spinning it into threads. Fiberglass is strong, durable, and impervious to many caustics and to extreme temperatures. composite, but thermoforming was chosen to eliminate the labor costs for hand lay-up and finishing. Flame-retardant Kydex 100 was chosen for the seats because its chemical resistance can withstand contact with batteries stored under the seats. Eight bucket-type seats are molded in one piece. Eight fiberglass-composite seats joined together served as the mold. |
