Self-healing, hydrophobic composites and related methods are provided. A method of repelling water may comprise forming a layer of a self-healing, hydrophobic composite comprising a porous network of entangled polymer fibers and a hydrophobic phase change material infused throughout the network, on a surface of a substrate to form a treated surface; and exposing the treated surface to water, wherein the treated surface exhibits a native water droplet contact angle which is greater than that of an untreated surface without the layer of the composite.

A fiber-reinforced thermoplastic resin includes a continuous fiber base material made from continuous reinforcing fibers, and a thermoplastic resin applied to the surface thereof. The thermoplastic resin coats the entire surface of the continuous fiber base material in a solidified state, and impregnates the continuous fiber base material while leaving voids therein, with these voids being formed intermittently in the direction in which the fibers are arranged. A laminate uses the fiber-reinforced thermoplastic resin base material.

A ventilation system with an inlet and outlet, the ventilation system being mounted to a wall, the ventilation system including: an acoustic member absorbing sound from the outlet; the acoustic member includes a film-like body portion opposed to the outlet, and a periphery portion disposed to connect the body portion to the wall, the periphery portion disposed to surround the body portion, the body portion defines a first air chamber communicating with the outlet and a second air chamber into which air flows from the inlet, a portion of an outer edge of the body portion is fixed to the periphery portion, and a remainder of the outer edge of the body portion is open and is a communicating portion allowing the first air chamber to communicate with the second air chamber.

An absorption sound insulation for motor vehicle interiors and luggage compartments with absorption/stiffening nonwovens or 3D absorbers is formed of partially or completely cellulose wool, and includes a wear layer, and an absorbent/stiffening nonwoven fabric laminated thereunder formed of rayon of solid individual phases having a multi-leg cross-sectional shape with at least three legs, in which the legs of the cross-sectional profile each have a length/width ratio of at least 2:1 and the individual titre is 0.5 to 5 dtex.

A heating pad includes a heat pad with an anterior and posterior side. The heat pad includes a first layer, a second layer, and a third layer. The second layer is located in between the first layer and the third layer. The first layer is located on the posterior side, while the third layer is located on the anterior side. The second layer has a wire selectively heated to increase the temperature of the heat pad. The third layer is a reflective material positioned to reflect heat from the second layer towards the first layer, decreasing heat emitted on the anterior side of the heat pad. The heating pad also includes a battery storage section for securing a battery. The battery is in electronical communication with the wire of the heat pad. The heating pad further includes an engagement mechanism to secure the heating pad to a user.

A method for improving the translation efficiency of fiber strength into composite strength is provided. A single unidirectional tape, single unidirectional fiber web or a stack of unidirectional web/unidirectional tape plies formed from partially oriented fibers/tapes is primed under mild conditions followed by subjecting the primed plies to an axial extension stress in the axial fiber direction of each fiber ply by passage through a compression apparatus. The axial extension stress extends the fibers, strengthening them, while also compacting the plies together and thereby forming a composite having improved strength. Production yield is improved by avoiding maximal fiber stretching and thereby avoiding typical manufacturing loss, and low weight composite armor having increased strength is achieved.
