    摘要： A process for producing fiber preforms for composite material components makes it possible to directly produce complex geometries in a flexible and low-cost manner by applying a plurality of dry fiber rovings independently of one another even in spatially uneven contours. It is no longer necessary to use cut fabric strips since fiber preforms are produced straight from the dry fiber rovings. This obviates the need to carry out production, transport and order picking processes. It is not necessary to cut fiber strips to size, and therefore a saving may be made on material. In addition, it is possible to increase the mechanical characteristic values in the composite material because it is not necessary to sew fiber webs. The described process can also readily be scaled since the number of dry fiber rovings arranged next to one another make it possible to vary the area which can be covered.

    摘要翻译： 用于生产复合材料部件的纤维预制件的方法使得可以以柔性和低成本的方式直接制造复杂的几何形状，即使在空间不均匀的轮廓中彼此独立地施加多个干纤维粗纱。 不需要使用切割织物条，因为纤维预制件直接从干纤维粗纱生产。 这样就不需要进行生产，运输和订单拣选过程。 不需要将纤维条切割成尺寸，因此可以节省材料。 此外，由于不需要缝合纤维网，因此可以增加复合材料中的机械特性值。 所描述的方法也可以容易地缩放，因为彼此相邻布置的干纤维粗纱的数量使得可以改变可被覆盖的面积。

    摘要： A fiber preform for producing fiber composite structures, a wall thereof including a first zone made from reinforcing fiber bundles having a first resin composition and a second zone made from at least one fiber tape comprising at least one unidirectionally directed reinforcing yarn strand having a second resin composition. The reinforcing fiber bundles in the first zone are oriented in different spatial directions to each other when viewed in a direction parallel to the extension of the thickness. Each reinforcing fiber has a length of from 3 to 50 mm, and contains the first resin composition in a concentration of from 1 to 10 wt % of the fiber weight. The wall of the fiber preform has a proportion of reinforcing fibers of more than 35 vol %, and the second zone forms a discrete region when viewed in a direction perpendicular to the thickness extension of the wall.

    摘要： A pre-impregnated yarn having a bundle made of reinforcing fiber filaments impregnated with a first resin composition infiltrated into the pre-impregnated yarn and at least partially connected via the first resin composition. The first resin composition contains at least two bisphenol A epichlorohydrin resins H1 and H2 in a weight ratio H1:H2 of 1.1 to 1.4, and an aromatic polyhydroxy ether P1. The pre-impregnated yarn has a second resin composition on the bundle outer side in the form of adhesive particles or drops. The second resin composition is solid at ambient temperatures and has a melting temperature in the range from 80 to 150° C. The bundle interior and at least 50% of the surface of the bundle outer side are free of the second resin composition.

    摘要： A process for continuous production of carbon fibres whereby stabilised precursor fibres are carbonised and graphitised with the help of high-frequency electromagnetic waves, characterised in that the stabilised precursor fibres are continuously conveyed, as the inner conductor of a coaxial conductor consisting of an outer and an inner conductor, through the coaxial conductor and a treatment zone; that the stabilised precursor fibres are irradiated in the treatment zone with high-frequency electromagnetic waves that are absorbed by the precursor fibres, which are thereby heated and converted into carbon fibres; and that the stabilised precursor fibres or carbon fibres are conveyed under an inert gas atmosphere through the coaxial conductor and the treatment zone.
