UNI-DIRECTIONAL FIBRE PREFORM HAVING SLIVERS AND CONSISTING OF REINFORCING FIBRE BUNDLES, AND A COMPOSITE MATERIAL COMPONENT |
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. |
