Multilayer articles comprising a coating layer comprising resorcinol arylate chain members bound to a support substrate via an optional intermediate tie layer.

摘要:
A method of forming a molding mat formed bundles of reinforcing fibers and bonding materials is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The bonding materials may be any thermosetting material having a melting point less than the reinforcing fiber. The molding mat may be formed by partially opening the wet use chopped strand glass fibers and filamentizing the bonding materials, blending the reinforcement and bonding fibers, forming the reinforcement and bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the bonding fibers but below the temperature of the glass fibers. The molding mat thus formed may be used as a reinforcement material in sheet molding compounds.

A method of forming a chopped strand mat formed of bonding materials and wet use chopped strand glass fibers (WUCS) which demonstrate a reduced occurrence of static electricity is provided. In one exemplary embodiment, the occurrence of static electricity on the glass fibers is reduced or eliminated by increasing the total solids content on the glass fibers, such as by applying an increased or excess amount of size composition to the glass fibers. Alternatively, an anti-static agent may be added directly to the sizing composition and applied to the glass filaments by any suitable application device. The antistatic agent may be applied to the wet chopped strand glass prior to chopping the strands or as the wet chopped strands are packaged. The static free wet use chopped strand glass fibers may be used in dry-laid processes to form chopped strand mats having a reduced tendency to accumulate static electricity.

A method of forming a multilayer insulation material formed of an acoustical composite layer and a first thermal layer is provided. The acoustical and insulting layer is formed of a polymer based thermoplastic material and reinforcing fibers. Preferably the reinforcing fibers are wet use chopped strand glass fibers (WUCS). The acoustical composite layer may be formed by opening the WUCS fibers, blending the reinforcement and polymer fibers, forming the reinforcement and polymer fibers into a sheet, and then bonding the sheet. A first thermal layer formed of one or more polymer based thermoplastic organic materials is then positioned on a first major surface of the acoustical composite layer. A second thermal layer of polymeric fibers may be optionally positioned on a second major surface of the acoustical composite layer. The multilayer acoustic material may be utilized in semi-structural and acoustical applications.

An acoustical and thermally absorbent chopped strand mat formed of thermoplastic bonding materials and bundles of reinforcing fibers is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The thermoplastic bonding materials may be any thermoplastic or thermosetting material having a melting point less than the reinforcing fiber. The chopped strand mat may be formed by partially opening the WUCS fibers and filamentizing the thermoplastic bonding materials, blending the reinforcement and thermoplastic bonding fibers, forming the reinforcement and thermoplastic bonding fibers into a sheet, and bonding the sheet. During bonding, the sheet is heated to a temperature above the melting point of the thermoplastic bonding fibers but below the temperature of the glass fibers. The melted thermoplastic bonding fibers act as a glue to hold the glass fibers in bundles. The chopped strand mat thus formed may be used as a reinforcement material in automotive applications.

An acoustical and thermally absorbent composite formed of thermoplastic bonding materials and reinforcing fibers is provided. The reinforcing fibers are preferably wet use chopped strand glass fibers (WUCS). The thermoplastic bonding materials may be any thermoplastic or thermosetting material having a melting point less than the reinforcing fiber. The composite material may be formed by partially opening the WUCS fibers and bonding fibers, blending the reinforcement and bonding fibers, forming the reinforcement and bonding fibers into a sheet, and bonding the sheet. The composite material is a lofted insulation product that may be used as a reinforcement backing for cladding such as vinyl siding. The composite material may be affixed to the siding by ultrasonic welding. After the composite material has been affixed to the siding, the siding product may be vacuum packaged within an air-impervious material to reduce the storage and/or shipping space required for the siding product.

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.
