  • Fiber reinforced composite and methods of forming the same
    Patent number: 7758785
    Abstract: A fiber reinforced composite is formed using a shrinkable die. A composite of fiber and resin is placed in the die and is compressed by shrinking the die to form a desired transverse cross-section. Optionally, the die is bent along its lengthwise extent to shape the composite in the die. After shrinking and optional shaping, the composite is cured to form the fiber reinforced composite.

  • Fibre Reinforced Composite and Method of Forming the Same
    Publication number: 20090065961
    Abstract: A method for forming an orthodontic device having a fibre reinforced composite is provided. The fibre reinforced composite has a fibre material within a matrix phase material. The fibre material comprises braided fibre material having a braid angle in the range from about 3° to about 87°, and more particularly in the range from about 10° to about 45°. The fibre reinforced composite is formed from a method which includes the steps of impregnating the fibre material with a monomer resin, shaping the fibre that is impregnated with the resin into a defined cross sectional shape suitable for use in the orthodontic device, and polymerising the monomer resin in the impregnated fibre to form the fibre-reinforced composite.
