▎ 摘　　要

NOVELTY - Fiber-reinforced biological material (biological matrix) comprises: (a) a cell culture in a solution that can be grown into a single sheet of biological matrix; (b) a tank containing the cell culture capable of holding fiber reinforcement at an exact position so that it is encapsulated into the growing biological matrix; (c) fiber-reinforcement that is inserted in a rack maintaining tension to maximize strength of the sheet; (d) fibers that are compressed into a plane as biological matrix dries and shrinks in vertical dimension; (e) strengthened biological matrix as a result of the addition of particles to cell culture that are incorporated into biological matrix; (f) a strong insulating layer once the biological matrix is dried; (g) a conductive layer with the addition of conductive materials that reduce the resistivity of biological matrix; and (h) a multi-layer composite material composed of layers of biological matrix each enveloping fiber reinforcement, and bonded by adhesive. USE - The fiber-reinforced biological material (biological matrix) is useful for building portions. ADVANTAGE - The advanced composite materials are environmentally benign. Automated culturing of fiber-reinforced materials can create an advanced composite that is extremely strong, tough, with desired physical characteristics tailored by the use of the reinforcing fibers (axial strength, uniform tensile strength, penetration resistance). It is far less expensive than current methods of laying up layers of fiber-reinforced plastics and is more environmentally benign. The growth of the biological film is substantially less detrimental to the environment than gluing layers of cloth together. There are no volatile organic compounds produced, no energy is required to heat the material other than maintaining a stable temperature in the tank for growth. DETAILED DESCRIPTION - Fiber-reinforced biological material (biological matrix) comprises: (a) a cell culture in a solution that can be grown into a single sheet of biological matrix; (b) a tank containing the cell culture capable of holding fiber reinforcement at an exact position so that it is encapsulated into the growing biological matrix; (c) fiber-reinforcement that is inserted in a rack maintaining tension to maximize the strength of the sheet; (d) fibers that are compressed into a plane as the biological matrix dries and shrinks in the vertical dimension; (e) strengthened biological matrix as a result of the addition of particles to the cell culture that are incorporated into the biological matrix; (f) a strong insulating layer once the biological matrix is dried; (g) a conductive layer with the addition of conductive materials that reduce the resistivity of the biological matrix; (h) a controlled growth period, followed by drying, allowing precise control of the thickness of the resulting dried sheet of biological matrix, including extremely thin sheets with a very high ratio of fiber to biological matrix; (i) protection of the sheet from environmental degradation by gluing it in layers and coating with a protective chemical or glue; (j) the creation of a mold of a desired shape, applying a chemical that allows the biological matrix to release easily; and (k) a multi-layer composite material composed of layers of biological matrix each enveloping fiber reinforcement, and bonded by adhesive. An INDEPENDENT CLAIM is included for a unit of growing the fiber-reinforced biological matrix comprising: (a) a tank holding nutrients and cells being grown into a biological matrix; (b) a rack holding reinforcing fibers in tension in the cell culture while the biological matrix grows around them; (c) a mechanism to lift the rack in and out of the tank; (d) a roll-to-roll mechanism to grow infinite-length sheets of biological matrix by slowly drawing them through a long tank while maintaining tension; (e) a washing mechanism to remove the remaining live cells and slime from the surface of the biological matrix; (f) a drying mechanism for controlled rate of drying under tension so the biological matrix has a precise, predictable dimension; (g) a boiler to create a sterile solution to feed the growing biological matrix; (h) rollers that can compress and join multiple layers of biological matrix into a thicker sheet; (i) a hydroponic system to deliver nutrients such as caffeine, sugar, or any other chemical or organic compound to increase the rate of growth or quality of the biological matrix; (j) a sprayer to evenly distribute solutions containing additives on the surface or from beneath to be incorporated into the biological matrix; and (k) a sterilization system so that no unwanted bacteria form around the biological matrix.
