An interior part having high mechanical strength while having a stitch pattern penetrating a base-material layer is provided. Furthermore, a method for manufacturing an interior part that improves strength of the base-material layer and enhances sewing compatibility is provided.

The interior part includes a skin layer joined to one surface of a base-material layer. The base-material layer contains reinforcing fibers and a thermoplastic resin binding the reinforcing fibers. A thread sewn between an opposite surface of the base-material layer with respect to the one surface and a design surface of the skin layer forms a stitch pattern provided on the design surface. A sewn area of the base-material layer is thicker than the periphery. The method includes a shaping step of shaping a fiber-reinforced board in which the thermoplastic resin is softened and forming an area to be sewn thicker than the periphery by releasing compression.

An interior part having high mechanical strength while having a stitch pattern penetrating a base-material layer is provided. A manufacturing method that improves strength of the base-material layer and enhances sewing compatability is also provided.

The interior part includes a skin layer joined to a base-material layer. The base-material layer includes reinforcing fibers and a thermoplastic resin. A thread sewn between the base-material layer and a design surface of the skin layer forms a stitch pattern provided on the design surface. A needle hole of the base-material layer is blocked at least at one of an opening on the base-material layer and a hole inside. The method includes shaping a fiber-reinforced board in which the thermoplastic resin is softened, and blocking at least one of the opening of the needle hole and the hole inside.

In order to produce a part (16) from a composite material, which is conductive at least on one of the surfaces thereof, the method consists of: the conductive overstitching (30) of a preform (20) of the part using electrically or thermally conductive threads (31, 32) with substantially parallel stitch lines (34) oriented in at least two intersecting directions. The parts obtained are adapted for the production of aircraft structures that may be subjected to lightning strikes and allow return currents from the electrical or electronic aircraft equipment and/or the discharge of heat by conduction.

Method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).

A stitched multi-layer fabric including an interior layer, a batting layer disposed over the interior layer, the batting layer configured to provide insulation, a barrier layer disposed over the batting layer, the barrier layer configured to inhibit fluid flow, a yarn stitched through and securing together the interior layer, the batting layer, and the barrier layer, the yarn forming stitch holes in the barrier layer, and a face layer disposed over the barrier layer, a melted portion of the barrier layer bonding the face layer and the barrier layer together and filling a portion of the stitch holes in the barrier layer.

A stitched multi-layer fabric including a face layer, a barrier layer disposed over the face layer, where the barrier layer is configured to inhibit fluid flow, a batting layer disposed over the barrier layer, a first yarn disposed over the batting layer, and a second yarn securing the first yarn to the batting layer, securing the face layer, the barrier layer, and the batting layer together, and forming stitch holes in the barrier layer. A melted portion of the barrier layer fills a portion of the stitch holes in the barrier layer.

A laminated structure includes a surface sheet material, and a backing material joined to a back surface of the surface sheet material. The surface sheet material has seams where the surface sheet material is sewn to another piece. The seams are provided in two positions that are adjacent to each other in an in-plane direction of the surface sheet material. The surface sheet material includes a backside uneven portion with a protrusion. The backside uneven portion is provided on a portion of the back surface within a region between the seams. The backing material is joined to the back surface of the surface sheet material such that the backing material is in surface contact with the back surface of the surface sheet material and the backing material conforms to the backside uneven portion.

A stitched multi-layer fabric including a face layer, a barrier layer disposed over the face layer, where the barrier layer is configured to inhibit fluid flow, a batting layer disposed over the barrier layer, a first yarn disposed over the batting layer, and a second yarn securing the first yarn to the batting layer, securing the face layer, the barrier layer, and the batting layer together, and forming stitch holes in the barrier layer. A melted portion of the barrier layer fills a portion of the stitch holes in the barrier layer.

A method for producing a fiber composite component assembly having at least first and second plate-shaped composite structures made from synthetic resin embedded fibers, the at least first and second fiber composite components having a plurality of partial regions not containing synthetic resin is described. The method includes positioning the at least first and second fiber composite components, the partial regions having been brought to flush conformity with each other, bonding the at least first and second positioned fiber composite components by the adhesive layer arranged in between, placing mechanical reinforcement means through the partial regions, infusing the dry partial regions with synthetic resin, and curing the synthetic resin placed in the partial regions.

A stuffer for clothing articles such as bags and purses is disclosed. One embodiment the purse stuffer is a sheet of an elegant, double quilted fabric that is stitched together to form a foldable stuffer. In one embodiment, the stuffer may be folded along one or more perpendicular folding stitch lines. In another embodiment, the stuffer may be folded along one or more, preferably four, parallel folding stitch lines. The stitch lines and the folding along increases the effect of the padding so as to form stuffers of varying sizes and shapes with a single construction. The various embodiments may be manufactured in different sizes to accommodate different size purses or bags.
