Abstract: Disclosed is a method for producing an antimicrobial heat-retaining fiber. The method includes spinning a spinning solution onto a fiber-forming resin. The spinning solution includes 1.0 to 6.0% by weight of carbon particles and 0.2 to 2.0% by weight of a metal alkoxide coupling agent. The spinning solution further includes 0.5 to 3.0% by weight of inorganic particles composed of a metal powder, a ceramic powder, or a mixture thereof By using the metal alkoxide coupling agent, the carbon particles and the inorganic particles are dispersed in a resin. Also disclosed is a fiber produced by the method. The fiber is prevented from breakage during spinning and is imparted with heat-retaining and antimicrobial functions due to the presence of the carbon particles and the inorganic particles. Further disclosed is a fabric manufactured using the fiber. The fabric can be prevented from deterioration of wash fastness.

Abstract: A fibre reinforced polymer (FRP) composite structure incorporates a woven preform containing tows of carbon or other advanced fibres and wires of shape memory alloy (SMA). The SMA wires are capable of absorbing much larger amounts of strain energy than the conventional components of FRP composites and hence enhance the impact resistance of the structure. The woven form incorporates the SMA into the structure in an optimum manner in terms of handling and performance.
