Provided is a hydrophobic silica aerogel blanket comprising holes, so that the diffusion of a surface modifier is facilitated in a blanket during a surface modification process to improve the efficiency of surface modification. Accordingly, the hydrophobic silica aerogel has not only excellent physical properties such as specific surface area and thermal conductivity, but also a controlled degree of hydrophobicity, and thus, can have high hydrophobicity.

A self-lubricating composite material is disclosed. The self-lubricating composite material can include discontinuous polymer fiber segments dispersed within a woven matrix of semi-continuous thermoplastic fiber. The woven matrix can be embedded within a thermosetting resin. Also disclosed are methods of manufacturing the self-lubricating composite material.

A glass filler of the present invention includes: a glass substrate; and a coating film including a surface treatment agent, the coating film covering at least a portion of a surface of the glass substrate. The glass substrate is a glass fiber having a flat cross-sectional shape. For the glass substrate, when a length corresponding to a minor axis of the flat cross-section of the glass fiber is represented by L1, a length corresponding to a major axis of the flat cross-section of the glass fiber is represented by L2, and a length corresponding to a fiber length of the glass fiber is represented by L3, a ratio of an average of L2 to an average of L1, (average of L2)/(average of L1), is 1.5 or more and 8 or less, the average of L1 is 1.0 μm or more and 10 μm or less, and an average of L3 is 80 μm or more and 160 μm or less. The surface treatment agent includes a silane coupling agent. A proportion of the coating film in the glass filler is 0.05 mass % or more and 2.5 mass % or less.

The invention is a flame-retardant fabric which includes a network of interconnected yarns. At least some of the yarns comprise fiberglass fibers. At least 30 weight percent, and preferably substantially all of the fiberglass fibers in the fabric are coated with a polymer composition comprising a fiberglass binding agent. The fabric of the present invention is used as a covering in furniture, such as a flame-retardant sock to surround the core of a mattress. The invention is also a method of producing a flame-retardant fabric. A fabric of interconnected yarns is provided. At least some of the yarns comprise fiberglass fiber. Those fiberglass fibers are coated with a coating composition comprising a polymer and a fiberglass bonding agent.

A fibrous insulation product having a plurality of randomly oriented glass fibers and a binder composition that holds the glass fibers together is disclosed. The fibrous insulation product has an R-value in the range of 10 to 54 and, after curing, has a density, when uncompressed, in the range of 0.30 pcf to 2.7 pcf. Furthermore, the fibrous insulation product includes glass fibers that, prior to the application of the binder composition, have an average fiber diameter in the range of 8 HT to 12 HT and a quantity of binder that is in the range of 2% to 10% by weight of the fibrous insulation product. The fibrous insulation product also has an average fiber diameter to density ratio (Fd/D) of less than or equal to 40 and a comfort factor less than or equal to 3.417(Fd/D)+60.
