An object of the present invention is to obtain a fiber-reinforced composite material achieving both lightweight properties and mechanical properties at a high level. The present invention provides a fiber-reinforced composite material including a resin (A) and a reinforcing fiber (B), and having: a porous structure portion having micropores with an average pore diameter of 500 μm or less as measured by a mercury intrusion method; and a coarse cavity portion defined by the porous structure portion and having a maximum length of more than 500 μm as a cross-sectional opening portion.

A method for manufacturing a synthetic non-perforated drainable material is disclosed herein. Generally, the method includes injecting a coating material with air, applying the air-injected coating material to the first side of the material, and curing the air-injected material such that it adheres. Once cured, the material has a highly efficient drainage rate that remains consistent throughout the life of the material.

According to an aspect of the present disclosure, A method of manufacturing a composite member including an aluminum member and a resin member that are bonded to each other, the method including: blasting on a surface of the aluminum member to form asperities on the surface of the aluminum member; performing hydrothermal treatment on the surface of the aluminum member having the asperities to modify a surface of the asperities into aluminum hydroxide and form a surface nano structure on the surface of the asperities; applying a binder containing a triazine thiol derivative to the surface of the asperities of the aluminum member modified into aluminum hydroxide and having the surface nano structure to form a coating to be bonded to the aluminum member; and bonding the coating and the resin member.

A method for manufacturing a container seal having an integral pull tab comprises providing a surface layer, an elastic layer, a top layer, an aluminum foil intermediate layer, and laminating a sealing adhesive layer of an adhesive thermoplastic resin or viscous agent to the intermediate layer. An adhesive surface and a non-adhesive portion are added to the thermoplastic resin layer, and placed on the aluminum foil to form a container seal laminate. The container seal laminate is cut to conform with an opening of the container to be sealed. The seal has an integral pull tab.

In accordance with at least selected embodiments, the application, disclosure or invention relates to improved membranes, separator membranes, separators, battery separators, secondary lithium battery separators, multilayer membranes, multilayer separator membranes, multilayer separators, multilayer battery separators, multilayer secondary lithium battery separators, multilayer battery separators, electrochemical cells, batteries, capacitors, super capacitors, double layer super capacitors, fuel cells, lithium batteries, lithium ion batteries, secondary lithium batteries, and/or secondary lithium ion batteries, and/or methods for making and/or using such membranes, separator membranes, separators, battery separators, secondary lithium battery separators, electrochemical cells, batteries, capacitors, fuel cells, lithium batteries, lithium ion batteries, secondary lithium batteries, and/or secondary lithium ion batteries, and/or devices, vehicles or products including the same, and/or the like.

Some embodiments comprise membranes comprising a first layer comprising a porous graphene-based material; a second layer comprising a porous graphene-based material; a channel positioned between the first layer and the second layer, wherein the channel has a tunable channel diameter; and at least one spacer substance positioned in the channel, wherein the spacer substance is responsive to the environmental stimulus. In some cases, the membranes have more than two layers of porous graphene-based material. Permeability of a membrane can be altered by exposing the membrane to an environmental stimulus. Membranes can be used in methods of water filtration, immune-isolation, timed drug release (e.g., sustained or delayed release), hemodialysis, or hemofiltration.

An ion exchange membrane having a structure that an ion exchange resin is filled in spaces of a porous base film, the porous base film has a structure that at least two porous olefin resin layers are laminated with a bonding strength of 100 gf/cm or more to less than 700 gf/cm and a Gurley air permeance of 500 sec/100 ml or less in terms of a 100 μm thick film. In this ion exchange membrane, base film has high air permeability though it has a multi-layer structure that a plurality of porous resin films are bonded together, and therefore a rise in electric resistance caused by the lamination of the base sheets is effectively suppressed.

An attachment tag that includes a tag portion having a first surface and a second surface, and an adhesive layer disposed on the second surface of the tag portion and configured to adhere to a product. The attachment tag also includes an elastomer portion having an expandable portion configured to further secure the attachment tag to the product and/or to secure the attachment tag to a second product, and a layer portion that is co-extensive with the expandable portion, and includes a bond zone that is bonded to the tag portion.

According to one embodiment, a polyisocyanurate foam board is described. The foam board includes a polyisocyanurate core that is produced from: an isocyanate, a polyol, and a phosphorous containing non-halogenated fire retardant. The foam board also includes a facer material that is applied to at least one surface of the polyisocyanurate core. The polyisocyanurate core has an isocyanate index greater than about 200 and is able to forms a sufficiently stable char when exposed to flame conditions to enable the polyisocyanurate core to pass the ASTM E-84 test. The foam board has an initial R-value of at least 6.40 and exhibits an ASTM E1354-11b test performance that is equivalent with or better than a similar foam board having a halogenated fire retardant, such as tris(2-chloroisopropyl)phosphate (TCPP).
