Panel, particularly a panel used for making furnishings such as doors, boards, tables, furniture or the like, which panel on at least one face thereof has at least a three-dimensional structure and which panel is composed of a mechanically rigid base or supporting sheet and a coating sheet for giving the aesthetic appearance to said panel, said coating sheet being superposed on at least one face of the base sheet, wherein the compound of said coating sheet is composed of thermoplastic polymers mixed with a vegetable and/or mineral filler, which compound gives such flexibility properties to the coating sheet that said coating sheet can be wound on itself.

A composite laminate has a primary axis of loading and comprises a plurality resin plies each reinforced with unidirectional fibers. The laminate includes cross-plies with fiber orientations optimized to resist bending and torsional loads along the primary axis of loading.

Woven fabrics are formed from high tenacity fibers or tapes that are loosely interwoven with adhesive coated filaments, to composite articles formed therefrom, and to a continuous process for forming the composite articles.

Apparatuses for forming a composite structure are configured to provide a tension at least partially along at least one ply of material as the at least one ply of material is supplied from a material feed assembly to a tool.

Provided is a rotor blade that may include a first layer having a first plurality of non-woven fibers oriented at first angle of about 10 to 30 degrees relative to a long axis of the rotor blade, a second plurality of non-woven fibers oriented at a second angle of about 60 to 75 degrees relative to the first plurality of fibers, and a third plurality of non-woven fibers oriented at a third angle of about 60 to about 75 degrees relative to the second plurality of fibers.

Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. An absorbent article can include an absorbent body and an outer cover. The absorbent article can also include a fluid-entangled nonwoven material. The absorbent body can be disposed between the fluid-entangled nonwoven material and the outer cover. The fluid-entangled nonwoven can include a first surface and a second surface. The nonwoven material can also include a plurality of nodes extending away from abase plane on the first surface towards the absorbent body. The nonwoven material can further include a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material. Individual openings of the plurality of openings can be disposed between adjacent nodes of the plurality of nodes.

A composite radius filler include a base portion and a tip portion. The base portion is formed of composite plies varying in overall width along an overall lengthwise direction and defining a variable cross-sectional shape of the base portion along the lengthwise direction. The base portion includes at least one transition zone having a transition start and a transition end along the lengthwise direction. The composite plies of the base portion are arranged in one or more stacks each stack having a predetermined fiber orientation angle sequence and a stack width that changes within the transition zone. The tip portion includes a plurality of composite plies formed into a generally triangular cross-sectional shape and stacked on top of the base portion.

A stringer made of composite material for reinforcing aircraft skin panels. Plies are introduced at 90? in a segment close to the stringer run-out, and progressively reducing the number of plies at 0?, such that the majority of the number of plies is at 90? in an segment adjacent to the run-out, so the stiffness of the run-out is reduced, and the load it supports is also therefore reduced. This is an alternative solution to the solutions already existing for getting the stringer run-outs to support a smaller load, thereby reducing both the risk of the plies of the stringer peeling off and the risk of separation between stringer and skin panel. A method of manufacturing said stringer is also provided.

A process for making a material adapted for the production of composite parts by a process in which a thermoplastic or thermosetting matrix is diffused within said material. The material includes at least one sheet of unidirectional carbon fibers associated on at least one of its faces with at least one conductive component associated or integrated with a permeable layer in a thermoplastic material or in a mixture of thermoplastic or thermosetting materials.

A unidirectionally stretchable substrate which has good shape retaining characteristics and whose weight can be easily reduced is provided. Unidirectionally 1 stretchable substrate has meshed material 2 that has a plurality of elastomeric linear members 3 arranged orthogonal to each other, the linear members having stretchability and thermoplasticity; and non-woven fabric 4 that is formed of a plurality of filaments 5, the filaments being made of a thermoplastic resin. Filaments 5 of non-woven fabric 4 have been drafted in one direction and are linearly arranged only in that direction. Non-woven fabric 4 is bonded to meshed material 2 such that direction y in which filaments 5 of the non-woven fabric 4 are arranged is parallel with one of directions y in which linear members 3 of meshed material 2 extend.
