Lobed tubular piece made of a composite with unidirectional fibers

A method for manufacturing a fibrous tubular structure including lobes, in which fibers are draped/deposited on a mandrel having a shape corresponding to that of the fibrous structure, includes draping/deposition carried out such that at least one group of fibers has a same orientation with respect to the axis (A) of said fibrous structure, then, the fibers having been draped over an angular sector less than the total periphery of the mandrel, one of the ends of the fibrous structure is separated from the mandrel in order to allow the continuation of the draping on the same mandrel.

Production of curved preforms

The invention relates to a device (1) for producing a curved preform (9) from flat semi-finished fiber material (8), comprising a shearing unit (2), which has at least two rotating rolling elements (3a, 4a), arranged spaced apart in a conveying direction (11), and a control unit (6) connected to the rolling elements, wherein at least one of the rolling elements is formed in a pivotal or tilting manner and a semi-finished fiber material sensing device (7) is provided, which is formed for sensing position information of the semi-finished fiber material conveyed through the shearing unit, wherein the control unit is further arranged for pivoting or tilting the at least one rolling element during the conveyance of the semi-finished fiber material, depending on the sensed position information from the semi-finished fiber material sensing device.

UNITARY SHAPED SOFT GOODS ARTICLE HAVING VARIABLE PHYSICAL CHARACTERISTICS BETWEEN DIFFERENT REGIONS

The present invention is directed to a shaped soft goods article that is unitary non-woven material having at least one three-dimensional shape. The article includes a first region substantially formed of a first formula and a second region substantially formed of a second formula. Between the first and second regions, there is an intermingling region that includes at least some of the first formula and the second formula. The first and second formulas are both comprised of at least one type of natural or synthetic fibers and at least one of crosslinkers, natural and/or synthetic adhesives, biobased and/or synthetic thermoplastics, including nanocellulose, and/or latex; however, the first and second formulas differ in at least one characteristic. An intermingling region exists where the first region (and first formula) intermingle with the second region (and second formula) meet.
