Some embodiments are directed to a preform including reinforcing fibres and shape memory alloy (SMA) wires, a composite material including a polymer matrix with a preform embedded therein, articles including a composite material, methods of making preforms, composite materials and articles.

The invention relates to a heat sink (1) having a main body (2) and a plurality of carbon-nanostructure-based fibres (CNB, 3), more particularly carbon nano tubes (CNT, 4) or graphene fibres, of which at least some are attached to the main body (2). According to the invention, the fibres (3, 4), by adhering to or supporting one another, form a volume structure (12), more particularly in the manner of cotton wool, felt or a spun yarn, or the fibres (3, 4) form loops (6) or a three-dimensional woven fabric.

A cartridge for an e-vaping device includes a reservoir configured to hold pre-vapor formulation, a vaporizer assembly configured to draw at least some of the pre-vapor formulation from the reservoir and vaporize the drawn pre-vapor formulation to form a vapor, and a superabsorbent polymer configured to absorb free water from pre-vapor formulation held in the reservoir. The superabsorbent polymer includes a cross-linked polyacrylate copolymer that is substantially inert to the pre-vapor formulation. The superabsorbent polymer may be included in a layer on one or more surfaces in the cartridge. The layer may include the superabsorbent polymer and a binder. The superabsorbent polymer may be included with the pre-vapor formulation in a formulation mixture. The superabsorbent polymer may be included in an interior of at least one element comprising the cartridge. The superabsorbent polymer may be included in a separate compartment in the reservoir.

A piezoelectric thread that includes a core thread; and a piezoelectric film wound around the core thread. The piezoelectric thread is constructed to generate a charge by energy imparted from outside of the piezoelectric thread.

An antibacterial yarn that includes a core yarn including a functional polymer that generates a charge by external energy and a first sheath yarn higher in hygroscopicity than the core yarn, the first sheath yarn covering at least a part of a periphery of the core yarn across an axial direction of the core yarn.

An article of apparel is disclosed that includes zones with a textile having a structure than changes or is otherwise modified by a physical stimulus, such as the presence of water or a temperature change, to modify a property of the textile. The zones may be along a center back area and/or side areas of the apparel, and the textile may increase in air permeability when exposed to water. In some embodiments, slits are formed in the textile.
