    摘要： A process for forming thermoplastic composites that uses wet use chopped strand glass is provided. Wet reinforcement fibers such as wet chopped strand glass fibers are opened by passing the fibers consecutively through a first opener, a condenser, and, optionally, a second opener. The opened reinforcement fibers are mixed with a resin and transferred to a first sheet former. The resin is preferably polypropylene fibers. An optional second sheet former may be used to form a final composite having high structural integrity. The resulting sheet may be optionally passed through a needle felting machine for mechanical strengthening. The sheet is then passed through a thermal bonder to thermally bond the reinforcement glass fibers and resin. The composite product that exits the thermal bonder can be subsequently used as a reinforcement in a molding process to produce composite articles.

    摘要： A method is provided for forming a wet-laid nonwoven glass fiber mat comprised of a plurality of bundles of fibers. The method includes the steps of adding chopped fibers to a water slurry containing a sufficient amount of a suitable hydrophobic agent to cause the fibers to form a plurality of bundles. The fibers are then formed into a mat which may be used in a number of reinforcement applications. A method is also provided for modifying the components in the water slurry to produce mats comprising either bundles of fibers or dispersed fibers.

    摘要： A dual-reinforced construction board is disclosed comprising a core having an upper surface and an opposing lower surface, a first reinforced fibrous facer adhered to the upper surface of the core and a second fibrous facer adhered to the lower surface of the core. Each of the first and second fibrous facer comprise a non-woven mat coated on a first surface with a coating composition. The first fibrous facer and optionally the second fibrous facer further include a reinforcement layer adhered to at least a portion of the first surface of the non-woven mat. The dual-reinforced construction board has a fastener pull-through strength of at least 400 lbf.

    摘要： An acoustically insulated machine including a source of noise positioned within a housing, a first insulation member positioned within the housing and including a first porous sound absorbing layer and a first dense layer, and a second insulation member positioned within the housing and including a second porous sound absorbing layer and a second dense layer. The first insulation member being is positioned closer to the internal source of noise than the second insulation member and the first insulation member being spaced apart from the second insulation member such that an air gap is formed between the first insulation member and the second insulation member.
