Abstract
Modular plastic structural composites formed from a mixture of (A) high density polyolefin and one or both of: (B) a thermoplastic-coated fiber material, or (C) polystyrene, poly(methyl methacrylate), or a combination thereof. Composites molded in the form of I-Beams and bridges constructed therefrom are also disclosed.
Claims11
A modular thermoplastic structural member comprising a web section disposed along a horizontal axis and one or more flange sections disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of said web section, wherein:
- the width of said flange sections measured perpendicular to said horizontal axis of said flange section is two to ten times the width of said web section measured perpendicular to said horizontal axis of said web section;
- the vertical dimension (thickness) of said flange sections are about one-tenth to about one-half the size of the vertical dimension of said web section without any flange sections;
- and said structural member is formed from a co-continuous immiscible polymer blend consisting essentially of
- a high density polyolefin and
- poly(methyl methacrylate), or poly(methyl methacrylate) and a thermoplastic polymer-coated fiber material, or poly(methyl methacrylate) and a thermoplastic polymer having fiber material embedded therein.
