    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 method of fabricating a composite material part such as a link. The method comprises the successive operations of applying reinforcing fiber layers (14a, 14b, 14c) that are braided around a mandrel over all or part of the length of the mandrel, the layers being superposed one on another. The method includes a step of cutting an intermediate reinforcing fiber layer (14a, 14b, 14c) after it has been applied, a step of withdrawing a cut portion prior to applying the following braided layer (14b, 14c), thereby locally building up an extra thickness of reinforcing layers on each portion of the cut layer that has remained in place, the extra thickness constituting local reinforcement of the part. Resin is subsequently injected into the various braided layers prior to the resin being polymerized in order to prepare a blank. The method applies in particular to the field of aviation.

    摘要： Portable apparatus for curing a part includes a wheeled frame having sliding part supports that move the part from a loading position to a curing position. A part clamping assembly is slidably mounted on the frame to apply clamping pressure to the part when the part is in the curing position in order to compact the part during a cure cycle. The clamping assembly includes a set of electrically heated shoes that heat the part to a cure temperature. A fan is provided to accelerate cool down the part after curing is complete. The heating and cooling operations are automatically performed by a programmed controller.
