    摘要: An article having non-planar portions, such as a pallet having a substantially flat deck member and a plurality of hollow leg members projecting integrally from the deck member, is molded as a one-piece unit from a loosely-felted, layered mat formed from a mixture of a resinous particle board binder and flake-like wood particles. The wood flakes have an average length of about 11/4 to about 6 inches, preferably about 2 to about 3 inches, an average thickness of about 0.005 to about 0.075 inch, preferably about 0.015 to about 0.025 inch, and an average width of 3 inches or less and no greater than the average length. Each layer of wood flakes in the mat lie substantially flat on a plane generally parallel to the major plane thereof and are randomly oriented to each other. The mat is placed between the male and female dies of a mold or press and compressed therein to substantially the desired shape under temperature and pressure conditions sufficient to bond the flakes together.

    摘要: An article, such as a pallet having a substantially flat deck member and a plurality of hollow legs projecting from the deck member, is molded as a one-piece unit from a papermill sludge. Dried, comminuted papermill sludge is blended with a fibrous reinforcing material, preferably a cellulosic material such as fibrous bark particles, and a resinous particle board binder, the resulting mixture of furnish is formed into a loosely fitted mat, and the mat is placed between dyes of a mold and press and compressed to substantially the desired shape under temperature and pressure conditions sufficient to bond the sludge and bark particles together.

    摘要: A pallet made of composite material including thermo-setting plastic reinforced with fiberglass forming a platform with integral ribs molded to and extending downwardly from the platform and steel rods molded into the integral ribs at a distance from the section of neutral axis of the cross section of the pallet to make optimum use of the high tensile strength and modulus elasticity of steel, thus providing the required section modulus. The reinforced plastic face serves as the compression side of the beam and provides the required impact resistance from the flat loading surface.
