Abstract
A new light weight particulate material is provided which comprises fruit (cherry) stones, or pits, stabilized against germination, weathering and general degradation caused by chemical or biological attack. Stabilization of the stones is accomplished by heat treatment alone or by heat treatment plus sealing of any openings in them. The stabilized stones are useful as a structural material, as a filler in solid syntactic composites, and as the primary component in tactic (open pore) composites. The loose stabilized stones can be used in applications such as "bean bags".
Claims11
A free-flowing mass of spheroidal fruit stones from which a major portion of volatilizable organic material has been removed to stabilize the stones against biological action, said processed stones being buoyant in water, and strong walled for structural use.
A free-flowing mass of fruit stones which have been biologically stabilized by removal of a major portion of volatilizable organic material, are about one centimeter or less in diameter, and are individually coated with a thin layer of polymeric material that is nontacky at room temperature.
A structure which comprises fruit stones that are about one centimeter or less in diameter and are individually coated with a thin layer of polymeric material that is nontacky at room temperature, wherein the fruit stones have been assembled and packed together and the polymer coating is then cured, resulting in a rigid, open-pored structure.
A composite article comprising a polymeric matrix material and fruit stones dispersed in the matrix material, said fruit stones being biologically stabilized by removal of a major portion of volatilizable organic material and constituting a majority of the volume of the article.
A laminate which comprises a monolayer of cherry stones biologically stabilized by removal of a major portion of volatilizable organic material .
