  • Process and machine for manufacturing lap siding and the product made thereby
    Patent number: 8110132
    Abstract: A process for manufacturing an elongated panel formed of synthetic materials including a polymer resin matrix, a filler and a fiber reinforcement. The process includes depositing the curable composition on a conveyor belt, distributing and leveling the curable composition prior to feeding the composition into a compression apparatus in which the curable composition is partially cured as it is compressed to form the panel. The machine for manufacturing the composite panel includes a mixer for the polymer system, filler and fiber reinforcement, a distribution apparatus that distributes the curable composition prior to feeding the composition into a compacting apparatus. The process and machine may be used to form a composite siding board that includes a grain pattern on at least one side.

  • Composite materials
    Patent number: 7037865
    Abstract: New composite materials having a high density of small particles, such as hollow microspheres, in a matrix material are disclosed. The microspheres are densely packed in the matrix material such that adjacent microspheres are positioned in contact with each other or very close together. Fiber flanking may be provided on the opposite sides of a layer of a core of composite material having the small particles and matrix material. Also disclosed are methods of making and using the composite materials.
