  • Patent number: 8383007
    Abstract: The present invention provides for a resin mixture that comprises a highly structured resin 40 and a less structured resin 50. The highly structured resin 40 and the less structured resin 50 are mixed to a ratio of between 1:9 and 4:1 by volume, with a more particular ratio of 1:5 to 3:1. The highly structured resin forms ordered micro regions and the ordered micro regions impose order on surrounding less structured resin molecules. The micro regions are essentially groups of the HS resin that will naturally form order structures.

    Abstract: The impregnation of a composite tape (56) having a porous matrix with HTC particles provides for permeating a fabric substrate layer (51) of the composite tape with HTC particles and impregnating an impregnating resin into the composite tape (51). The HTC particles in the fabric (51) layer are comprised of a meso-micro mixture, which is between 1:4 to 4:1 meso sized particles to micro sized particles. Other smaller particles may also be included at lesser concentrations. The impregnating resin itself may also contain HTC particles.

  • Patent number: 7955661
    Abstract: A method for the treatment of micro pores within a mica paper that includes: obtaining a silane with a molecular weight of between approximately 15 and 300, adding the silane to the mica paper, and reacting the silane with the inner surface of the micro pores within the mica paper. After this, a resin is impregnated into the mica paper, and the resin binds to the inner surfaces of the micro pores with the mica paper through the silane. In one embodiment, the mica paper is compressed by an amount between 5% and 30% of its original thickness. In another embodiment, the mica paper is compressed both prior to reacting the silane and during impregnation with the resin.

  • Patent number: 7851059
    Abstract: A high thermal conductivity resin that is made up of a host resin matrix (42) and high thermal conductivity fillers (30) that are mixed within the host resin to form a resin mixture. The fillers comprise at least 3-5% by weight of the resin mixture, and the fillers are from an average of 1-100 nm in at least one dimension, and where the particles are smaller than an average of 1000 nm in the particles' longest dimension. The host resin matrix forms an ordered resin shell (40) around the high thermal conductivity fillers (30), whereby resin molecules are aligned perpendicular to the surface of the high thermal conductivity fillers. An overlap of the ordered resin shells (44) is formed between the high thermal conductivity fillers such that continuous pathways for ordered resin shells are created through the resin mixture.

  • Patent number: 7846853
    Abstract: An electrical insulation paper that is made of mica flakelets (22), having an average size range of 0.01 to 0.05 mm in their thinnest dimension, hexagonal boron nitride (26), which has an average size range of 10 to 1,000 nm in their longest dimension, and a resin matrix. The mica flakelets and the hexagonal boron nitride are mixed and formed into a paper (17), and the resin is added to the paper after formation, the ratio by weight of the hexagonal boron nitride to the mica flakelets is directly proportional to the average size of the hexagonal boron nitride compared to the average size of the mica flakelets, within an adjustment factor.

  • Patent number: 7268174
    Abstract: The present invention relates to homogeneous alumoxane-LCT-epoxy polymers and methods for making the same. The homogeneous alumoxane-LCT-epoxy polymers comprise alumoxane-containing sub-structures evenly dispersed and essentially completely co-reacted with the LCT-epoxy sub-structures. The alumoxane sub-structures are organically bonded to the LCT-epoxy sub-structures. This produces homogeneous alumoxane-LCT-epoxy polymers that are substantially free of particle wetting and micro-void formation, with improved thermal conductivity properties without compromising on other desired structural integrities.
