Abstract
This invention relates to novel composites comprising plastic and plant material derived from members of Parthenium spp. and, in particular, Parthenium argentatum (also known as guayule), Parthenium tomentosum or Parthenium incanum. The invention is also directed to composites that possess insect, fungal, and microbial resistance. Products made from composites of the instant invention are useful to make numerous items, particularly those used for construction such as lumber, plywood, particleboard, fiberboard, poles, railroad crossties, or the like.
Claims19
A composite comprising Parthenium species lignocellulosic plant material having naturally occurring resin and synthetic oraganic polymer plastic, wherein the ratio of plastic to plant material ranges by weight from 80% plastic:20% plant material to 20% plastic:80% plant material.
