Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 5 seconds as well as very low packing volumes (for more efficient use of storage space within a vehicle). All coatings, in particular elastomeric, preferably, though not necessarily, non-silicon coatings, and coated airbags meeting these criteria are intended to reside within the scope of this invention.

The invention discloses a method for modifying wood by filling grafted cell walls with organic monomers and polymerization-filling cell cavities, which relates to a wood modification method. The invention solves the problem of difficulty in simultaneously enhancing mechanical properties and durability of wood in the existing wood modification method. The method comprises the following steps: 1, preparing organic acid anhydride solution; 2, soaking the wood with the organic acid anhydride solution; 3, filling grafted wood cell walls with organic acid anhydride by heating; 4, preparing the organic polymerizable monomer solution; 5, soaking the wood with the organic polymerizable monomer solution; and 6, carrying out polymerization-filling on the wood cell cavities with the monomers by heating. Since organic function micromolecules firstly enter the wood cell walls, the method realizes filling and bonding and eliminates a great deal of hydroxyl groups in the cell walls, thereby enhancing wood durability; and the wood cell cavities are soaked by the organic polymerizable monomers to initiate the polymerization and realize the filling of the cell cavities, so that the wood has higher mechanical properties and durability.

Novel airbag coating compositions comprising at least two separate and distinct layers are provided. The first layer (base coat), being in contact with the airbag surface, comprises a composition of at least one coating material which may comprise up to 30% by parts of the total amount of material in the first layer of a silicone resin which provides excellent adhesion, excellent tensile strength, and overall lower cost than standard silicone airbag coating materials. The second layer, being a coating for the first layer, provides excellent reinforcement and blocking characteristics to permit effective potential long-term storage and optimum use upon the occurrence of a collision. Such a second layer (topcoat) is preferably a silicone material but may also be selected from the group consisting of homopolymer and coplymer resins based on ethylene, propylene, acrylates, methacrylates, vinyl esters, acrylic acid, methacrylic acid, polyurethanes, polyamides, and inorganic materials such as talc, silica, silicate, calcium carbonate, alumina, and the like. This two-layer system permits excellent strength and blocking properties to prevent undesired adhesion between portions of the target airbag when stored as well as to prevent seam combing at relatively low cost due to the materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.
