摘要: A mold half is provided particularly for laminated parts which are to be ded from fiber components, with the mold half being formed with an inside surface matching the negative contour of the part to be molded therein. The mold half is formed of a shaped plate material which has been plastically deformed along deformation lines at angles determined by the shape of the part to be molded. The mold half is affixed upon a support member which fits the shape of the deformed material.

摘要: A mold component for forming a member consisting of a nondevelopable surface, such a member being an airfoil such as a wing or the like, is provided with an interior cavity in the shape of a developable surface which approximates the nondevelopable surface. In forming the mold cavity, points of equal tangential inclination on the non-developable surface are joined by straight lines and then the areas between the straight lines are formed as flat planar surfaces, thereby to form a developable surface which is an approximation of the nondevelopable surface. A flat planar development is then formed from this developable surface and bends are made therein at the straight lines in order to form thereby the mold cavity. A substantial number of said bends extend non-parallel to each other and none of the bends intersect.

摘要: A disk wheel, especially a railroad wheel, has a composite construction of single piece metal hub and a single piece metal rim connected to each other by a wheel disk of fiber reinforced composite material providing exclusively adhesive bonds. The wheel disk transmits shearing stress between hub and rim. The rim is provided with two radially inwardly extending rim flanges. The hub has two radially outwardly extending hub flanges. The shearing stress transmitting wheel disk (12) has a radially outer rim contacting surface (9) adhesively bonded to the rim (3) and rim flanges (7), and a radially inner hub contacting surface (8) adhesively bonded to the hub (2) and hub flanges (6). The wheel disk (12) is inserted into the space between the concentrically arranged hub and rim as long as the composite material is not yet cured and hence sufficiently deformable. The wheel disk is exposed to compression during curing. After the curing a cover disk is adhesively bonded to the rim, hub, and wheel disk on both sides of the wheel. Preferably, the wheel disk is made of a plurality of box type or shell type truncated sectors.

摘要: A safety steering column made of wound fiber-reinforced synthetic materials manufactured economically and simply, yet simultaneously with due regard to its deformation characteristics in response to axial compressive overloading under various operating conditions. For this purpose the steering column is wound as a rotationally symmetrical tubular body having five component integral sections (3, 4, 5, 6, and 7). The component sections (3 and 7) are relatively thick-walled connecting tubes to provide a torque input section and a torque output section provided with connectors (8) for steering wheel hub and for a steering mechanism. An intermediate section (5) of the steering column is a cylindrical, relatively thin-walled tube with a larger diameter (d.sub.2) compared to the connecting sections. Conical transition sections (4 and 6) preferably extend between the intermediate section and the connecting tubes or sections. The wall thickness of these transition sections diminishes uniformly from the connecting section in the direction toward the intermediate section for improving the buckling ability. A geodetic winding procedure is preferably applied for winding the columns.

摘要: A webbing reinforced by carbon fibers is heated during its resin impregnation by passing an electric current through the carbon fibers whereby the carbon fibers act directly as heating mats in a system of layers of fiber reinforced material. Thus, the use of heated molds has been obviated which is of particular advantage especially for large scale structural components, especially if such components have a complicated configuration.
