Abstract
A system for modified resin and composite material and methods therefor generally comprise a plurality of clay nanoparticles dispersed in a high temperature resin to provide enhanced microcrack resistance and maintenance and/or improvement of thermal and mechanical properties. In one embodiment, the invention further comprises a reinforcement disposed in the modified resin, wherein the reinforcement and modified resin together comprise a composite material.
Claims20
A modified resin, comprising:
- a main resin;
- and
- a plurality of clay nanoparticles dispersed in the main resin.
A microcrack resistant composite material, comprising:
- a modified resin, comprising:
- a high temperature phthalonitrile resin;
- and
- a plurality of clay nanoparticles dispersed in the high temperature phthalonitrile resin;
- and
- a reinforcement disposed in the modified resin comprising at least one of fiber, tow, and fabric.
A composite material according to claim 11, wherein the modified resin comprises about 1-10 weight percent clay nanoparticles.
A method for modifying a resin to at least one of substantially maintain and improve glass transition temperature and shear strength of the resin while increasing microcrack resistance, comprising:
- dispersing a plurality of clay nanoparticles in a high temperature phthalonitrile resin, wherein the clay nanoparticles comprise about 1-10 weight percent of the high temperature phthalonitrile resin.
