Wood - Based Composites and Panel Products - Quiz

Quiz Question

1. The basic element for composite wood products may be the fiber, as it is in paper, but it can also be larger wood particles composed of many fibers and varying in size and geometry.
True
False
2. Conventional wood composite materials fall into five main categories based on the physical configuration of the wood used to make the products: plywood, oriented strandboard, particleboard, hardboard, and cellulosic fiberboard.
True
False
3. A number of additives are used in the production of conventional composite products. One of the most notable additives is wax, which is used to provide finished products with resistance to aqueous penetration.
True
False
4. What does Table 10-2 illustrate about?
(Refer Pg 10-5)
Standards for frequently used panel products
Classification of wood composite boards
Basic wood elements, from largest to smallest
None of the above
5. Decorative plywood has traditionally been made from softwoods such as Douglas fir, Southern Pine, white fir, larch, western hem- lock, and redwood.
True
False
6. Plywood is a flat panel built up of sheets of veneer called plies, united under pressure by a bonding agent to create a panel with an adhesive bond between plies.
True
False
7. Broadly speaking, two classes of plywood are available, covered by separate standards: (a) construction and industrial, and (b) hardwood and decorative.
True
False
8. What does APA stand for?
American Plywood Association
American Plywood Agency
American Paper Association
None of the above
9. Although plywood is an engineered wood product, it is also used as a component in other engineered wood products and systems in applications such as prefabricated I-joists, box beams, stressed-skin panels, and panelized roofs.
True
False
10. Oriented strandboard is an engineered structural-use panel manufactured from thin wood strands bonded together with waterproof resin under heat and pressure, and it is used extensively for roof, wall, and floor sheathing in residential and commercial construction.
True
False
11. The term fiberboard includes hardboard, medium-density fiberboard (MDF), and insulation board. Several things differentiate fiberboard from particleboard, most notably the physical configuration of the comminuted material.
True
False
12. Insulation boards are low-density, wet-laid panel products used for insulation, sound deadening, carpet underlayment, and similar applications.
True
False
13. What does CABO stand for?
Council of American Building Officials
Court of American Building Organization
Council of American Building Organization
None of the above
14. Medium-density fiberboard is frequently used in place of solid wood, plywood, and particleboard in many furniture applications. It is also used for interior door skins, mouldings, and interior trim components.
True
False
15. Punching consists of pressing the unconsolidated mat of fibers with a textured form. This process results in a slightly contoured board surface that can enhance the resemblance of the board to that of sawn or weathered wood, brick, and other materials.
True
False
16. Sanding consists of reducing products into standard sizes and shapes. Sanding consists of overhead- mounted saws or multiple saw drives.
True
False
17. What does Figure 10-15 illustrate about?
(Refer Pg 10-24)

Laboratory-produced low-density, cement-bonded composite panel. Full-scale panels such as these are used in construction.
Inorganic-Bonded Composites
Portland-Cement-Bonded Composites
None of the above
18. Pozzolans are defined as siliceous or siliceous and aluminous materials that can react chemically with calcium hydroxide (lime) at normal temperatures in the presence of water to form cement.
True
False
19. What does ASTM stand for?
American Society for Testing and Materials
American Standards for Testing and Materials
American Standard for Testing and Mechanics
None of the above/p>
20. Portland cement, when combined with water, immediately reacts in a process called hydration to eventually solidify into a solid stone-like mass.
True
False
