Abstract
Modular plastic structural composites having a web section disposed along a horizontal axis and at least one flange section disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of the web section, wherein said composite is formed from a mixture of (A) high density polyolefin and (B) a thermoplastic-coated fiber material, poly-styrene, or a combination thereof. Composites molded in the form of I-Beams and bridges constructed therefrom are also disclosed.
Claims14
A modular plastic structural composite comprising a web section disposed along a horizontal axis and at least one flange section disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of said web section, wherein said composite is formed from a mixture of (A) high density polyolefin and (B) a thermoplastic-coated fiber material, polystyrene, or a combination thereof.
An essentially planar modular plastic structural composite comprising a grooved side and an integrally molded tongue-forming side, each side perpendicular to the plane of the composite, in which the composite is formed from a mixture of (A) high-density polyolefin and (B) a thermoplastic-coated fiber material, polystyrene, or a combination thereof, wherein the grooved side defines a groove and the tongue-forming side is dimensioned to interlockingly engage a groove having the dimensions of the groove defined by the grooved side, and the grooved side and tongue-forming side are dimensioned so that a plurality of the essentially planar modular plastic structural composites may be interlockingly assembled to distribute a load received by one assembly member among other assembly members.
