A patient interface device and cushion for the device are respectively disclosed, for preferred CPAP and BiPAP breathing masks. The cushion has a composite structure with an open rounded polygonal profile defining a mask side layer and a slip-resistant fibrous patient side layer, with an intermediate barrier layer positioned between the first and second layers. The layers are integrally bonded together into a three-dimensional conformation defining a J-shaped cross section and an inboard patient side curl opening into an air chamber juxtaposed with one or more of the patient's airways. The body exhibits flexibility between about 4 and about 10 Taber Stiffness Units. Method and apparatus for making the cushion are further described.

Impregnated veil and compression molding process of reinforcing fiber pre-impregnated continuous and discontinuous thermoset and thermoplastic materials. Veils are incorporated within the process, filming or laminating stages of the pre-pregging, either hotmelt or solvent based processes, in a variety of chosen resins. The veils help to improve visual part quality, reduce fiber splitting, and provide an isolating material in applications where incompatible materials must exist.

A method for trim preparation of car interior parts includes the steps of cutting out templates of natural jute or linen fabric primer and a second natural cotton fabric or fiber paper, and impregnation of the fabrics with a water-based adhesive resin in each of the fabrics and drying thereof. The method also includes the steps of fabric pressing, forming a structure by adding an adhesive layer and a decorative sheet, applying primer on the decorative layer and drying it, and applying at least one layer of varnish onto the primer layer and drying it.

A method of manufacturing a composite fan blade with an outer part and a core includes laying up a plurality of continuous plies to achieve a stack, placing the core on a central portion of the stack of continuous plies to achieve an unfolded preform; folding the contin-uous plies about the core, such that the central portion of the stack folds about the core and the first portion is superimposed to the second portion, to achieve a folded preform; apply-ing pressure to the folded preform to achieve a consolidated curved folded preform; curing the consolidated curved folded preform to achieve the composite fan blade.

The present invention generally relates to processes for compression molding a composite article comprising at least one prepreg and at least one transformer film.

A method includes laminating a plurality of fiber reinforced sheets to create a charge; and shaping, by pressing, the charge created in the lamination step into a shaping mold. The charge has a predetermined angle layer including the plurality of fiber reinforced sheets, the fiber direction of which is aligned in a single direction. The predetermined angle layer has n-number of constitutional layers (n≥2) ranging from a first constitutional layer to an n-th constitutional layer each including the plurality of fiber reinforced sheets, wherein the n-th constitutional layer is laminated on an (n-1)-th constitutional layer, the plurality of fiber reinforced sheets in each of the constitutional layers have dividing portions which are along the fiber direction and which are disposed one by one at respective positions within a predetermined range along the fiber direction in the predetermined angle layer.

A method is provided for producing an SMC component provided with a unidirectional fiber reinforced. The method includes: a) a blank of a unidirectional fiber reinforced is laid on the tool surface of a lower part of a preform tool, b) the preform tool is closed by moving a preform upper part and the preform lower part of the preform tool towards each other, thus forming the unidirectional fiber reinforced; c) the unidirectional fiber reinforced is pre-cured in the preform tool by heating; d) the removed unidirectional fiber reinforced together with at least one nondirectional SMC semi-finished product are laid in a press tool, onto the tool surface of a press tool lower part; e) the press tool is closed, wherein a press tool upper part and the press tool lower part of the press tool are moved towards each other to mold together the unidirectional fiber reinforced and the at least one non-directional SMC semi-finished product; and f) the produced SMC component is fully cured by heating.

Methods and apparatus for additive manufactures of complex parts using co-aligned continuous fibers are disclosed. Filament subunits having complex shapes are fabricated and inserted into a mold cavity. The layup is compression molded to form a complex part having high tensile strength.

Tool arrangement for compacting a composite preform assembly comprising a support structure preform and an array of component preforms each extending from the support structure preform and spaced apart along the support structure preform. The tool arrangement comprises a support tool defining a lay-up surface for laying up the support structure preform; a plurality of component moulds, each component mould comprising a pair of blocks configured to cooperate with one another to receive and compact a respective component preform extending from the support structure therebetween, each block having a compaction surface for engaging the component preform and a driving surface.

A composite blade formed by laying up composite layers containing reinforcing fiber and resin, the composite blade comprising: a blade root mounted in a blade groove; an airfoil extending from the blade root to a front end side; and a metal patch mounted between the blade groove and the blade root, and bonded to the blade root.
