A method, and an apparatus associated therewith, for detecting plastic tube ends clamped in a butt welding machine, the plastic tube ends being planed by means of a plane, which can be introduced between the plastic tube ends, and subsequently being heated by means of a heating mirror, which can be introduced between the plastic tube ends, and the plastic tube ends are welded together after removal of the heating mirror, the plane and/or the heating mirror being tilted in between the plastic tube ends by means of a controlled movement, wherein detection or sensing of the plastic tube ends during the controlled movement of tilting in the plane and/or the heating mirror is carried out by means of at least one sensor arranged on the plane and/or on the heating mirror.

A method of joining first and second layers of polymeric composite material includes disposing a portion of a molded insert having a bottom end into a top surface of a first layer of material and then applying a layer of adhesive between the top surface of the first layer and a bottom surface of a second layer of material to create a bond-line thickness. Next, a top surface of the second layer is pierced with a headless end of a fastener and interlocked into the molded insert. A layer of protective coating is then applied to the top surface of the second layer of material to cover the interlocked fastener.

A process for welding of at least two separate vehicle panels (12, 14) to form an integral part (16) for a vehicle. There is provided at least one first panel (12) including a first weld line area (18) and at least one second panel (14) including a corresponding second weld line area (19), the second weld line area (19) abutting in a weldable relationship to the first weld line area (18). The first and second weld line areas (18, 19) have at least one first weldable portion (22) and at least one second portion (24) at which welding is substantially hindered during welding attachment of the first and second panels (12, 14). The process includes applying a curable adhesive at each second portion (24), placing in a welding fixture and welding the panels (12, 14) at each first weldable portion (22) such that the panels (12, 14) are held together during curing of the adhesive.

The invention relates to a method for welding a polyolefin plastic and a plastic using a primer, said primer containing at least one maleic anhydride containing polymer and at least one polyester. The invention also relates to correspondingly bonded products.

The present invention relates to a method for producing a squeeze tube with maximal surface area labeling and a tube produced thereby.

A coated composite component includes, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric. A method for producing a coated composite component including, in this order, a composite component, a fluorine-containing film and/or a fluorine-containing woven fabric, knitted fabric or crocheted fabric, and a tear-off fabric.

A fiber composite component assembly (100) includes a fiber composite component (3) including a base material and a fiber material, and a tolerance compensation layer (5) for joining the fiber composite component (3) to a further component (1), the tolerance compensation layer (5) including a fiber composite portion (17) and/or a further layer portion (7). A fiber composite component system (200) including a fiber composite component assembly (100) and a further component (1) joined to the fiber composite component assembly (100), as well as a method for producing a fiber composite component system (200), is also provided.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.

A method of forming a composite article. One step involves applying adhesive on surfaces of a plurality of sublaminate units, each ply of each sublaminate unit comprising fibers impregnated with resin which has been initially cured to 30% to 50% of full cure. The initially cured sublaminate units are then arranged in a stack, which stack is pressed against a surface of a forming tool. While pressure is being applied, the stack is heated to an intermediate temperature above a glass transition temperature of the resin for a time interval sufficient to intermediately cure the resin to 50% to 70% of full cure to form a composite laminate having a contour defined by the surface of the forming tool. Then the resin is finally cured at a final temperature higher than the intermediate temperature.

Wind Turbine Blade (12) Leading Edge (24, 30, 88) Protection Method In a first aspect of the invention there is provided a method of applying an erosion shield (22) to a leading edge region (30) of a wind turbine blade (12). The method comprises providing a wind turbine blade (12) comprising a blade shell (26) having an aerodynamic profile and defining a leading edge region (30); providing an erosion shield (22) made of a polymer material, the erosion shield (22) having an inner surface (36) to be bonded to the leading edge region (30) of the blade shell (26), and an outer surface (38, 84, 98) to be exposed in use; activating (44) the inner surface (36) of the erosion shield (22), and cleaning (42) the inner surface (36) of the erosion shield (22) using a solvent. The method further comprises applying a layer of wet adhesive (66, 68, 72A) to the inner surface (36) of the erosion shield (22); applying a layer of wet adhesive (66, 68, 72A) to the leading edge region (30) of the blade shell (26); arranging the erosion shield (22) against the leading edge region (30) of the blade shell (26) such that wet-to-wet adhesive (66, 68, 72A, 72, 96) contact is established between the inner surface (36) of the erosion shield (22) and the blade shell (26), and curing the adhesive (66, 68, 72A, 72, 96) to bond the erosion shield (22) to the leading edge region (30) of the blade shell (26).
