Fiber-reinforced composite material and method for manufacturing same
An object of the present invention is to develop and provide a fiber-reinforced composite material having an “elongation” feature in addition to a high strength and a high elastic modulus. Further, an object of the present invention is to address problems of brittleness and peeling in the conventional fiber-reinforced composite materials. A fiber-reinforced composite material containing the bagworm silk thread as reinforcing fibers is provided.
1. A fiber-reinforced composite material, containing a polymer matrix(es) and reinforcing fibers,
wherein the reinforcing fibers comprise bagworm silk threads, and
wherein the reinforcing fibers are placed in three or more directions onto a non-woven fabric sheet comprising the composite material.
2. The fiber-reinforced composite material according to claim 1 , further containing organic fibers other than the bagworm silk threads, inorganic fibers, or a combination thereof.
3. The fiber-reinforced composite material according to claim 1 , further comprising a fabric or knit composed of all, or part of, the bagworm silk threads.
4. The fiber-reinforced composite material according to claim 1 , wherein the polymer matrix is selected from the group consisting of a resin, a glue, a starch, an agar, or a combination thereof.
5. The fiber-reinforced composite material according to claim 1 , wherein the bagworm silk threads in the fiber-reinforced composite material has a mass percentage ranging from 0.5 mass % to 50 mass %.
