The disclosure relates to a method of manufacturing a fibre reinforced composite, wherein the surface of the fibre reinforced composite modified by using a laser radiation. In particular, the pre-treatment is performed before a bonding process. Time-consuming and dust generating grinding of the surface can be avoided.

The invention relates to a process (100) for manufacturing an object (1) made of thermoplastic polymer composite from at least two parts (10) made of thermoplastic polymer composite, said thermoplastic polymer composite comprising a fibrous reinforcement and a thermoplastic polymer matrix, said process comprising the steps of: arranging (120) the two parts (10) made of thermoplastic polymer composite adjacently or overlapping at an assembly interface zone (11), and heating (130) to melt the thermoplastic polymer matrix at said assembly interface zone (11), so as to form an object (1) made of thermoplastic polymer composite comprising a welded interface (12).

A method for producing a centrifugal pump impeller having a base plate, which is a single piece with pump blades and a cover plate, which consists of a thermoplastic material, wherein contact areas are available, which are heated and melted by means of ultrasonic excitation and form a close bonded connection after cool-down. The objective of the invention is to ensure inherent stability with the individual parts and a simple and reliable pre-assembly as well as a fixed mechanical connection, wherein only a small amount of excitation energy is required, with a centrifugal pump impeller comprising a base plate and cover plate.

The present invention relates to a motor vehicle luminous device including at least one first portion that is transparent to at least one laser beam, the portion having at least one first polymer material, and at least one second portion that absorbs the laser beam and is transparent to at least some of the visible spectrum, including at least one second polymer material, the second portion being laser welded to the first portion.

A method for forming a pipe elbow comprises cutting a first precursor from a pipe. The pipe has an inner diameter surface and an outer diameter surface and a central longitudinal axis. The first precursor has a first end and a second end off parallel to the first end. Machining forms an interior surface having an arcuate centerline. Machining forms welding interfaces at the first end and the second end.

To provide a balloon catheter and an apparatus and method for manufacturing the balloon catheter, whereby the degree of welding can be appropriately adjusted and the balloon catheter can be formed so as to have a desired surface profile suitable for various uses including medical use. With a shaft 14 inserted through a catheter tube 30a inserted into an end portion 28b of a balloon and also with a pressure tube 32a fitted around a welding section where the end portion 28b of the balloon 28 is lapped over the catheter tube 30a, the shaft 14 is heated by emitting laser light from a laser radiation unit 8 to the welding section while the shaft 14 is rotated by a chuck, to weld the welding section.

There is provided a resin molded product including a first member and a second member which are laser welded. A laser welded portion includes a first welding portion which is welded by laser welding of galvano method and a second welding portion which is welded by laser welding of flash method or laser welding of scanning method.

The invention relates to a method for producing flexible tube bodies (18) for packaging tubes from a film substrate (1) which has a print, preferably on an outer side (2), and which has or consists of at least one weldable plastic layer and which comprises a first longitudinal edge side (8), which extends in a longitudinal direction, and a second longitudinal edge side (8′) parallel thereto and spaced apart therefrom, wherein the film substrate (1) is shaped by shaping means (23) to form a tube, and the two longitudinal edge sides (8, 8′) are in particular welded to one another with the formation of a longitudinal weld seam, wherein a strip (12) is arranged, in the region of the abutment point and/or of the longitudinal weld seam, in the interior (17) of the film substrate (1) shaped to form the tube and is connected, in particular welded, to the longitudinal edge sides (8, 8′) at least in certain regions or portions. According to the invention, prior to the formation of the longitudinal weld seam, at least one longitudinal edge side (8′) is shaped, in particular cut, in such a way that, in the film substrate (1) shaped to form the tube, the longitudinal edge sides (8, 8′) bear against one another, in particular in abutting fashion, radially only in the region of the outer side (2) with at least one tip (9) formed by the shaping operation.

A composite panel manufacturing process with interlocking connections. The method includes laying out the first sheet of pre-preg epoxy carbon fiber, upon a polished and released aluminum tool. A second sheet of epoxy fiberglass is laid out over the top side of the first sheet. Rigid structural foam is laid on top of the second sheet of epoxy fiberglass. A third sheet of pre-preg epoxy fiberglass is laid on top of the rigid structural foam. A fourth sheet of pre-preg epoxy carbon is laid on top of the third sheet of pre-preg epoxy fiberglass with heavy resin/top side out to form a plurality of panels. The plurality of panels are cured to form a multilayer panel. Core material is removed along one edge of a first multilayer panel to make a U-shaped channel having a base and parallel flanges. A grooved slot is cut along one edge of the next multilayer panel. The panels are joined at the corner using an adhesive.

Composite fabrication system and associated methods. In one embodiment, a composite fabrication system comprises a molding tool that includes a forming surface at least partially disposed within a constrained space, and a foamable material that expands inside of the constrained space to form an expanded material that presses a layup of one or more composite layers against the molding tool. The composite fabrication system further comprises a curing device configured to cure the layup to form a composite part, and a cutting wire embedded in the constrained space that is heated and configured to cut the expanded material into pieces that are removable from the constrained space.
