  • Patent number: 11447897
    Abstract: A method for making puncture resistant material is made by aggressively twisting high modulus continuous filament polypropylene yarns and weaving the twisted yarns into a tight weave. Batting materials are placed adjacent the woven layer (which may comprise one or more individual woven layers) to form a stack and the stack is needlepunched to form a consolidated material. The material is heat treated and calendared and the finished product may be used in applications where puncture resistance is required, such as in a shoe insole material.

    Abstract: Low porosity fibrous materials, articles formed therefrom and processes for their formation. Multiple plies of high tenacity, multifilament elongate bodies are optionally stitched together and pressed as a set without being laminated, adhered or thermally fused to each other. Pressing spreads the component filaments of the elongate bodies, forcing the filaments to occupy spaces between adjacent fibers and thereby reducing porosity of the complete multi-ply material.

    Abstract: The purpose of the present invention is to provide a shell laminated structure realizing a further light weight formation of a helmet while improvement for shock absorbing characteristic is assured. There is provided a laminated structure in which either the net-like member or the sheet-like member having many holes is placed at an entire region of the shell having a reinforcing base material or between the laminated layers at a part of the shell in such a manner that the sheet-like member is extended along the layer to which its front and rear surfaces are faced, bitten into the layer and fixed. With such an arrangement as above, a further light weight formation of the shell is realized while a high safety characteristics of the helmet is assured.

  • Patent number: 6656858
    Abstract: A laminate wall structure which can be used as an exterior wall in manufactured housing and site built construction is made up of a low density layer having a density of from about one-half pound to three pounds per cubic foot, a second, reinforcing layer laminated to the low density layer and, optionally, a cellulosic layer laminated to the second, reinforcing layer. The low density layer is preferably a foamed polymer layer, the second, reinforcing layer is a polymer fabric, a biaxially oriented polymeric film or a fiberglass reinforced material and the cellulosic layer can be impregnated with an adhesive and/or resin in order to strengthen the laminate structure. This laminate wall structure has a low weight and yet is strong enough to meet wind zone wall diaphragm requirements for housing construction.

  • Patent number: 6586352
    Abstract: A simple, inexpensive, drillable, reduced CTE laminate and circuitized structure comprising the reduced CTE laminate, is provided. The reduced CTE laminate comprises: from about 40% to 75%, preferably from about 55% to 65%, by weight resin; from about 0.05% to 0.3%, preferably from about 0.08% to 0.10%, by weight curing agent; from about 25% to 60%, preferably from about 30% to 40%, by weight, woven cloth; from about 1% to 15%, preferably from about 5% to 10%, by volume, non-woven quartz mat. The present invention also generally relates to a method for reducing the CTE of circuitized structures, and to methods for making reduced CTE laminate and circuitized structures comprising reduced CTE laminate.

    Abstract: A simple, inexpensive, drillable, reduced CTE laminate and circuitized structures comprising the reduced CTE laminate, is provided. One embodiment of the reduced CTE laminate comprises: from about 40% to 75%, preferably from about 55% to 65%, by weight resin; from about 0.05% to 0.3%, preferably from about 0.08% to 0.10%, by weight curing agent; from about 25% to 60%, preferably from about 30% to 40%, by weight, woven cloth; from about 1% to 15%, preferably from about 5% to 10%, by volume, non-woven quartz mat. The method for making reduced CTE laminate and laminate structures comprises the following steps: providing non-woven quartz mat; providing a prepreg, preferably B-stage cured to not more than about 40%, preferably not more than 30% of full cure; sandwiching the non-woven quartz mat between two layers of prepreg, and reflowing the resin of the prepreg into the quartz mat.

  • Patent number: RE39709
    Abstract: A multilayer papermaker's press felt fabric comprising in combination a woven first fabric layer, typically a double layer fabric, has a cross machine direction pin seam. A second fabric layer is located on the paper side face of the first fabric layer, and a layer of needled batt is applied to the paper side face of the second layer binding the layers together. A flap comprising a short length of the second fabric layer with attached batt overlays the pin seam area in the first layer. The second layer comprises a plurality of relatively narrow strips, which are located with a lateral edge at a first cant angle of from more than 1° to less than 20° to the machine direction. A third layer, similar to the second layer, can be included on the machine side of the first layer; the strip widths, the cant angles, and the direction of the cant angle relative to the machine direction for each of the two strips need not be the same. The fabric is assembled using a spiral winding technique.
