High temperature materials with low moisture uptake made from lichen metabolites

摘要

A cured polycyanurate, thermoset resins, and methods of producing the same that will have both high thermal resistance as well as high hydrophobicity. Naturally occurring 5-alkylresorcinols and synthetic analogs can be made into cyanate ester. Composites made from these products will have greater durability against atmospheric water exposure. Applications include use in fiber-reinforced composite materials for lightweight, strong, and water-resistant aerospace components.

主权项

1. A process for making thermoset resins and thermoplastics, comprising:
isolating resorcinolic lipids from plant and/or animal sources having 5-n-alkylresorcinolswherein said ‘n’ is selected from the group consisting of n=1 being orcinol, n=3 being divarinol, and n=5 being olivetol;
converting said 5-n-alkyl resorcinolic lipids into 5-n-alkyl resorcinolic dicyanate ester lipids; and molding said thermoset resins and thermoplastics in a component or coating a component to protect against extreme heat and moisture.
