  • Method for manufacturing resin mats
    Patent number: 7896991
    Abstract: The present invention relates to a method for the manufacture of sheet molding compounds (SMC) in which the required glass fiber nonwovens are manufactured in-line and have an inhomogeneity of 10% or less, a weight per unit area of 400 g/m2 or higher and a strength of less than 10 N. Furthermore, the present invention describes resin mats that comprise the glass fiber nonwovens in accordance with the invention that represent valuable intermediate products.
    Type: Grant

    Assignee: Johns Manville
    Inventors: Sean Charles D'Silva, Thomas F. Stehlin
  • METHOD AND SYSTEM FOR FORMING REINFORCING FIBERS AND REINFORCING FIBERS HAVING PARTICULATE PROTUBERANCES DIRECTLY ATTACHED TO THE SURFACES
    Publication number: 20100196697
    Abstract: Reinforcing fibers with small particles having a longest average dimension of approximately 0.01 nanometer to approximately 30 micrometers physically and/or chemically bonded directly to their surfaces to form protuberances thereon and a method and system for making these modified fibers are disclosed. The particles directly bonded to the surfaces of the fibers, serve to enhance physical properties of composite articles which incorporate such fibers as reinforcement.
