摘要： A method of forming a three dimensional fiber structure is disclosed which comprises the steps of a) providing a starting material which comprises liquid carrier, fibers and binder; b) passing the starting material over a substrate so as to deposit fibers onto the substrate; c) forming a three dimensional fiber matrix; and d) curing the binder. The flow of material onto the substrate may be controlled such that the flow of a starting material over the substrate is chaotic and fibers are laid down in a three dimensional structure containing a high proportion of voids. The preform may be pressurized while moist and is cured under pressure. The fibers may comprise carbon fibers; recycled carbon fiber has been found to be particularly useful. The resulting preform may be stochastic and is suitable for use in ablative and braking applications.

摘要： Calcein-PVA film and Calcein solution dosimeters is made for high dose applications. Systematic evaluation of dosimetric properties for the films is being conducted and was found useful for routine dosimeter in industrial radiation processing. The color bleaching of CA-PVA film and CA solution increases gradually with increasing absorbed dose in the dose range of 5-30 kGy for film, and 0.25-1 kGy for solution. The dose sensitivity increases significantly with increase of concentration of CA dye. The response of the CA-PVA films was slightly affected by relative humidity and temperature. The stability of film dosimeters and solutions after irradiation was very high and were stable for up to 30 days.

摘要： A method for printing a three-dimensional part with an additive manufacturing system, which includes providing a part material that compositionally has one or more semi-crystalline polymers and one or more secondary materials that are configured to retard crystallization of the one or more semi-crystalline polymers, where the one or more secondary materials are substantially miscible with the one or more semi-crystalline polymers. The method also includes melting the part material in the additive manufacturing system, forming at least a portion of a layer of the three-dimensional part from the melted part material in a build environment, and maintaining the build environment at an annealing temperature that is between a glass transition temperature of the part material and a cold crystallization temperature of the part material.

摘要： The technical solution relates to the field of processing polymers and can be used in various branches of the national economy for manufacturing hollow articles of the bodies-of-revolution type (tubes), and in particular for manufacturing semifinished biodegradable polymeric stents which are usable in medicine for replacing hollow organs, for example blood vessels. The apparatus for manufacturing thin-walled bodies of revolution comprises a heatable expander which is mounted rotatably about a longitudinal axis, and a feeder for supplying moldable material, said feeder being mounted above the expander so as to be movable therealong, wherein the lower part of the feeder is heatable, the expander is hollow with a reflective internal surface, and the heater of the expander is in the form of a laser, the radiation of which is transported into the expander. The use of the apparatus will make it possible to reduce the thermal action on a polymer when producing semi-finished articles with defined geometrical dimensions from polymeric materials.

摘要： A method for manufacturing a three-dimensional object layer by layer by applying and selectively solidifying a constituent material in powder form layer by layer by supply of energy has the steps: applying a layer (32+33) of the powdery constituent material (11) having a pre-determined height (h) onto a support (6) or a previously at least selectively solidified layer of the constituent material, and supplying energy (14) from an energy source (13) into the applied layer at positions corresponding to the cross sectional area of the object to be manufactured for selectively solidifying the constituent material. The step of applying the layer having the pre-determined height (h) is subdivided into a step of applying a first partial powder layer (32) having a first height (h1) which is smaller than the pre-determined height (h), and a step of at least applying a second partial powder layer (33) having a second height (h2) which is smaller than the pre-determined height (h), wherein the total height. (h1+112+ etc.) of the applied partial powder layers (32, 33, etc.) corresponds to the pre-determined height (h), and between the step of applying the first partial powder layer and the step of applying the second and possibly further partial powder layers, the powder layer applied last is heated.
