摘要： A rapid method for forming carbon structures from flexible polyurethane resin strands, which faithfully reproduces the geometry of the uncarbonized polyurethane resin strands, the first step of which comprises infusing the polyurethane resin strands with a curable furan resin or resin precursor. The furan resin as a curable liquid resin or resin precursor swells the polyurethane strands during infusion and forms a gel-like alloy structure with the polyurethane resin as the solid phase. An important step in the method which assists in preventing cracking during carbonization and which is essential to faithful strand geometry reproduction is the substantial removal of the liquid resin or resin precursor coating from the polyurethane strand surfaces after the infusion or swelling step. The method allows rapid carbonization with less than about five hours heating of the infused structures without cracking. The resulting carbon strands remain crack-free and strong even when exposed to rapid temperature variations. The carbonized strands are preferably in the form of vitreous or glassy carbon and are particularly useful for high temperature applications in the presence of neutral or reducing gas conditions or in a vacuum.
摘要翻译：一种用于从柔性聚氨酯树脂线形成碳结构的快速方法，其忠实地再现了未碳化的聚氨酯树脂线的几何形状，其第一步包括用可固化的呋喃树脂或树脂前体浸渍聚氨酯树脂线。作为可固化液体树脂或树脂前体的呋喃树脂在输注期间使聚氨酯线膨胀，并以聚氨酯树脂为固相形成凝胶状合金结构。有助于防止碳化过程中的裂纹，并且对于忠实的股线几何形状重现是必要的方法中的重要步骤是在输注或膨胀步骤之后从聚氨酯线股表面上显着除去液体树脂或树脂前体涂层。该方法允许快速碳化，少于约5小时加热输注结构而不开裂。即使暴露于快速的温度变化，所得的碳链也保持无裂纹和强烈的强度。碳化的链优选为玻璃状或玻璃状碳的形式，并且对于在中性或还原性气体条件或真空中存在的高温应用是特别有用的。

摘要： Treatment of the inner surfaces of an open-cell porous mass which may be damaged by pressure waves generated by exothermic reaction of a gaseous material present in the cavities of the porous mass and in a confined space. Treatment comprises (a) a gaseous material that produces short-term heat-energy is introduced into the cavities of the porous mass and the confined space, the volume of the space being greater than that of the porous mass to be treated, so that an empty space exists between porous mass and the walls of the confined space; (b) a non-flammable and non-decomposible gaseous material is introduced into the space in amount such that the pressure wave is largely reduced but the gaseous material is not essentially removed from the cavities of the porous mass, and (c) a reaction is triggered off in the gaseous material in the cavities of the porous mass before a diffusion between the gaseous material and the non-flammable material occurs to an appreciable extent. The non-flammable material is nitrogen, and the gaseous material a mixture of natural gas (or hydrogen) and oxygen.

摘要： A METHOD FOR THE BONDING OF FIBERS BY PROVIDING A BONDING AGENT AT THE POINT OF CONTACT OF THE FIBERS IS DESCRIBED. AN ESSENTIAL FEATURE OF THE METHOD IS EXPOSING CONTACTING FIBERS, WHICH MAY BE MONOFILAMENTARY OR MULTIFILAMENTARY, AND WHICH HAVE BEEN COATED WITH A FILM OF A POLYMER WHICH IS SOLIDIFIED SUFFICIENTLY TO RESIST FLUID FLOW OF THE POLYMER ON THE FIBERS, TO A SOLVENT FOR THE POLYMER FILM, PREFERABLY IN VAPOR FORM FOR EASE OF CONTROL OF THE PROCESS, WHICH THEN RETRACTS TO THE POINTS OF CONTACT BETWEEN THE FIBERS BECAUSE OF THE ACTION OF THE SOLVENT. PARTICULARLY PREFERRED IN THE METHOD IS THE USE OF ELASTOMERIC POLYMERS FOR BONDING AND THE PRODUCTS OBTAINED THEREBY. THE FIBERS CAN BE IN THE FORM OF KNITTED, WOVEN AND NON-WOVEN OR NEEDLE PUNCHED BATT OR MAT FABRICS. THE BONDED PRODUCTS ARE USEFUL IN THE SAME GENERAL AREAS WHERE UNBONDED PRODUCTS ARE USED. PARTICULARLY USEFUL ARE THE DESCRIBED BONDED KNITTED NYLON STOCKINGS.
