摘要:
Provided in some embodiments is a method that includes coupling portions of one or more members using at least one impact driven fastener. At least one impact driven fastener includes at least one penetrating portion formed of plastic, and at least one head portion having a heat deformation temperature less than about 250° F. Plastic of the penetrating portion provides the penetrating portion with a flexural strength greater than about 9500 psi. The method also includes applying heat to at least partially deform the head portion of at least one fastener.
摘要:
Plastic impact driven fasteners having relatively high flexural strength and relatively low heat deformation temperature are provided. Additional embodiments relate to methods of using the fasteners. For example, the fasteners may be used in a tire retreading process. In such a case, one or more fasteners may be used to secure new tread to a tire core before and/or during a curing process. The curing process may also cause deformation of the fastener, thereby eliminating the need to remove the fasteners after the curing process.
摘要:
A continuous impact-driven fastener pack made of ultra-high strength plastic composite materials, for example, thermoplastic or thermoset materials for use in standard impact driving fasteners machines. The individual fasteners have sufficient compressive strength and flexural modulus such that the fastener may be used with commodity woods for construction, furniture making, or for building boats. Further, this fastener pack is non-corrodible and provides plastic fasteners having a length/diameter ratios of a working nail or staple, e.g., heretofore unavailable.

A continuous nail pack made of ultra-high strength plastic composite materials, for example, thermoplastic or thermoset materials for use in standard nailing machines. The individual nails have sufficient compressive strength and a flexural modulus such that the nail may be used for nailing into commodity woods for construction, furniture making, or for building boats. Further, this nail pack is non-corrodible and provides plastic nails having a length/diameter ratio of a working nail heretofore unavailable.

摘要:
An adhesive tape is provided which comprises a woven cloth, a polymer embedded into the cloth so as to cause the warp and weft fibers of the cloth to bond together at their overlapping points but not to completely encase the fibers, and a pressure sensitive adhesive coated onto at least a portion of the polymer, wherein the adhesive tape is hand tearable in the down-web and in the cross-web direction. A method of manufacturing such a tape is also provided.
摘要:
The present invention provides a metal/polymer composite comprising a polymeric substrate and a sintered mat of randomly-oriented metal fibers embedded therein, the fibers having a substantially circular cross-section and a diameter of about 10 to 200 .mu.m. The polymeric substrate is typically a thin, flexible sheet-like material having a pair of planar surfaces. The polymeric substrate is preferably thermoformable. If thermoformability is desired the metal will have a melting point of less than the thermoforming temperature of the polymeric substrate. The thermoformable metal/polymer composite of the present invention may be stretched to at least 20%, and often can be stretched at least 200% of its original dimensions, at least in certain regions, without loss of electrical continuity or EMI shielding properties. The present invention also provides a method of making a metal/polymer composite and a sintered mat of randomly-oriented metal fibers.
摘要:
A pressure-sensitive adhesive comprising a blend of at least two components, wherein the first component is at least one pressure-sensitive adhesive and second component is at least one thermoplastic material, wherein the components form a blended composition having more than one domain and, wherein one domain is substantially continuous (generally, the pressure-sensitive adhesive) and the other domain is substantially fibrillous to schistose (generally, the thermoplastic material). The second component can be (a) at least one thermoplastic elastomer, (b) at least one elastomer with a tackifying resin or (c) at least one elastomer.
