  • Process of making a consolidated part
    Patent number: 5380480
    Abstract: A thermoplastic composite sheet is used as a tool or tool liner for thermoforming thermoplastic composite sheets into parts having uneven sections. A more uniform consolidation of the part is achieved that has not been previously attainable in open mold processing at high forming temperatures.
    Type: Grant
    Filed: August 4, 1993
    Date of Patent: January 10, 1995
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Richard K. Okine, Albert S. Tam
  • Method for forming a structural panel with decorative facing and product thereof
    Patent number: 5238725
    Abstract: A panel having a honeycomb core and thermoplastic resin facings with adhered decorative polyvinyl fluoride overlayer is shaped in a press after being preheated to the softening temperature of the resin and the placing of the heated thermoplastic resin facing in registry with the overlayer which is preheated, thus pressing the two together in the press.
    Type: Grant
    Filed: December 21, 1990
    Date of Patent: August 24, 1993
    Assignee: E. I. Du Pont de Nemours and Company
    Inventors: Michael J. Effing, Dennis A. Nollen, Richard K. Okine, Albertus P. Walrave
  • Method of producing a composite article
    Patent number: 5066442
    Abstract: A new method of forming composites or laminates into complex shapes has been developed. A process using a die with piercing studs allows control of fibers motion during processing, leading to better composite parts.

  • Process for making composites of stretch broken aligned fibers and product thereof
    Patent number: 5045388
    Abstract: A stretch broken fiber reinforced resin tow is formed from resin reinforced with continuous filaments by tensioning the tow while heating it to a temperature sufficient to soften the resin in the tensioning zone to break all of the filaments in a random manner.

  • Composites of stretch broken aligned fibers of carbon and glass reinforced resin
    Patent number: 4863780
    Abstract: A coating of a viscous lubricant applied prior to stretch-breaking permits forming slivers of stretch-broken carbon fibers. When an anti-static ingredient is added to the viscous lubricant cohesive slivers of stretch-broken glass fibers can be formed. Composites of matrix resin reinforced with these slivers exhibit high strength, tensile stiffness, and good formability.
