- Selected properties of MDF and flakeboard overlaid with fiberglass mats.
Abstract Nonwoven fiberglass face laminates have long been applied to consolidated wood-based composites to improve their performance and serviceability. In this study, fiberglass mats with 50 percent resin binder were applied as face laminates to unconsolidated wood fiber or flake mats, then hot-pressed to make overlaid medium density fiberboard and ......
- GLASS-FIBER-REINFORCED RESINS REPLACE METALS
Two new grades of glass-reinforced polybutylene-terephthalate (PBT) compounds are alternatives to short-fiber glass-filled PBT, polypropylene (PP), and nylon resins. LNP Verton WF-7007 and WF-700-10 have long glass-fiber loadings of 35 and 50%, respectively. This enhances tougbness, strength, and stiffness over a wide temperature range. These properties, combined with the resins' ......
- Advances in braiding and preforming lead composites
news at SAMPE.
Advances in Braiding and Preforming Lead Composites News at SAMPE Heading the list of recent innovations in advanced composites are developments in 3-D braiding and fiber placement processes for making stronger preforms in less time. The 35th International SAMPE Symposium and Exhibition, held during April in Anaheim, Calif., also produced ......
- Composite insulation shields key LNG components.
LNG conversion facilities include special features for the handling of extremely cold materials. One key feature is insulation that protects components from extreme cold and keeps ambient heat out of LNG tanks and pipes. Inexpensive wood- and paper-based composite materials can often provide adequate insulation, but they lack the strength ......
- Machining fiber-reinforced
composites.
Nontraditional machining operations such as laser machining, water jet and abrasive water jetcutting, electrical discharge machining, and ultrasonic-assisted machining have become necessary with the development of new metal-matrix and ceramic-matrix composites. Machining of fiber-reinforced composites (FRC) differs significantly from machining of conventional metals and their alloys. In the former, the ......
- Long-fiber PBTs minimize warpage. (Keeping Up with
Materials).
Ticona in Summit, N.J., has introduced Celstran PBT compounds with 30%, 40%, and 50% long-glass fibers or with 40% long carbon fiber. The new grades contain a PBT resin formulated specifically to improve the mechanical properties of long-fiber composites. The tailored resin and proprietary compounding technology are said to ensure ......
- THERMAX[R] Sheathing joins a core of
glass-fiber-reinforced polyisocyanurate foam with aluminum foil
facers.
THERMAX[R] Sheathing joins a core of glass-fiber-reinforced polyisocyanurate foam with aluminum foil facers. Delivering outstanding thermal performance (R-6.5 at 1 inch), high moisture resistance, reliable dimensional stability, and improved fire performance, THERMAX is suitable for load-bearing and non-load-bearing walls in steel stud and masonry construction. THERMAX is part of Dow's ......
