摘要： An automatic lay-up machine is disclosed for composite material article having anisotropic resistance in tension. A layer of fiber material, either unidirectional or fabric weave, is dispensed between a supply roll and a take-up roll. This material is advanced over a cutting table having at least one and preferably a plurality of cutting molds, each mold cutting a profile of a portion of an article being fabricated and leaving a continuous scrap webbing for gathering at the take-up roll. The material is placed under tension across the cutting table, compressed, and cut at the molds to extract the individual layers having the desired sections utilized in fabricating the article. This process is repeated with the molds indexing in rotation with respect to the material so that successive layers filling the molds align their respective fibers in varying directions. Sufficient scrap material is left between the cutting table and the take up roll that tension can be drawn through the un-severed fiber sections as material is sequentially advanced across the cutting table. Where pre-impregnated composite tape or fabric are used, refrigeration of the supplied tape with following adhering to form a unitary article or article part occurs. Alternately, built up layers of composite layers without resin can be impregnated with resin. This article or article part is then cured as a unitary mass.

摘要： A hybrid centrifuge rotor having a rotor core surrounded by a prestressed anisotropic reinforcement ring is disclosed. The rotor core may be made from aluminum and an anisotropic reinforcement ring may be a cylindrical filament wound ring, made from graphite fiber and epoxy resin. The rotor core is manufactured to have a nominally greater diameter than the inner diameter of the reinforcement ring. This rotor core, during the manufacturing process, is subjected to a cryogenic environment where the diameter is shrunk down so that the rotor body may fit and telescope within the reinforcement ring. The rotor body core and reinforcement ring assembly, upon attainment of ambient temperatures, have an interface fit wherein substantial outward force from the rotor body core prestresses the reinforcement ring so that a light weight and strong centrifuge rotor is disclosed.

摘要： A composite material centrifuge rotor and process of construction of the rotor is disclosed. A rotor having high stiffness of fibers, preferably carbon, bound together with resin is disclosed. The rotor includes a top disk, a bottom disk and a spacer belt spacing the two disks apart to form a rotor assembly. The top and bottom disks are fabricated by overlying multiple layers of tape, the tape being made from longitudinally extending and parallel fibers held together with resin. Successive layers of tape are oriented so as to vary the longitudinal direction of the fiber with respect to a preselected radius vector from the spin axis of the rotor. When the tape is compiled in multiple layers to a thickness of the top and bottom disk, the tape is compressed between two metal plates and cured at a temperature well above the expected autoclave temperature of sterilization of the rotor. Thereafter, the entire assembly is wound by a peripheral belt with resin impregnated high stiffness fiber. This fiber is cured and shrinks during curing to exert hoop tension around the periphery of the rotor assembly. This hoop tension in turn radially prestresses the rotor equal and opposite to the radial tension forces of centrifugal force when the rotor is in use.

摘要： In the production of fiber reinforced axially symmetrical wound bodies each of predetermined length, by winding fibers or strands of fibers saturated with a hardenable plastic onto a mandrel, alternating layers of circumferential windings and layers with criss-cross windings being placed on top of one another, and, after hardening of the plastic, removing the mandrel, the winding is carried out to simultaneously produce a plurality of identical wound bodies axially juxtaposed on the mandrel by the steps of: winding at least one circumferential layer by attaching a plurality of fibers or strands corresponding to the number of bodies to be wound at axially spaced locations along the mandrel and winding all of the fibers or strands simultaneously on the mandrel with mutual axial spacings approximately corresponding to, or somewhat greater than, the length of each wound body; winding at least one criss-cross winding layer by attaching at least one fiber or strand to the mandrel and winding the fiber or strand over the combined length of the juxtaposed layers of circumferential windings along the mandrel; and dividing the completed wound layers into individual sections forming the respective wound bodies which are then removed from the mandrel.

摘要： A carbon filament wound hollow cylinder comprising at least two carbon filament layers, an inner axial direction-wound layer and an outer circumferential direction-wound layer, characterized in that the modulus of longitudinal elasticity in the circumferential direction of the inner layer is lower than that of the outer layer. Such a cylinder is capable of preventing possible crack formation after shaping owing to its much reduced residual stress exerted due to thermal expansion of a mandrel during shaping and capable of being stably employable as a rotary drum for, ultracentrifugation because compressive stress is exerted effectively to cancel tensile stress caused by thermal stress for causing interlaminer delamination during high speed rotation.
