Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A composite building material formed from a co-continuos immiscible polymer blend consisting essentially of a high density polyolefin and poly(methyl methacrylate), wherein said blend is characterized by an extruded co-continuous polymer blend morphology. 2. The composite building material of claim 1 , wherein said high-density polyolefin is high-density polyethylene (HDPE). 3. The composite building material of claim 1 , wherein said co-continuous immiscible polymer blend consists essentially of from about 20 to about 60 wt % of a poly(methyl methacrylate) component containing at least about 90 wt % poly(methyl methacrylate) and from about 40 to about 80 wt % of a high-density polyolefin component containing at least about 75 wt % high-density polyethylene (HDPE).
