摘要:
A method of fastening a second object to a first object includes: providing the first object with an attachment surface; providing the second object; placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition has a resin having a first viscosity and being in a flowable state; pressing the first and second objects against each other and causing mechanical vibration to act on at least one of the objects until the resin composition experiences a vibration induced activation, which includes at least one of reduction of the viscosity of the resin compared to the first viscosity and activation of particles dispersed in the resin. The pressing and mechanical vibration are continued or repeated until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity.

The present invention provides a method for firmly and inexpensively bonding at low temperature a polymer film to another polymer film or to a glass substrate without the use of an organic adhesive. A method for bonding a polymer film includes a step (S1) for forming a first inorganic material layer on part or all of a first polymer film; a step (S3) for forming a second inorganic material layer on part or all of a second polymer film; a step (S2) for surface-activating the surface of the first inorganic material layer by bombarding with particles having a predetermined kinetic energy; a step (S4) for surface-activating the surface of the second inorganic material layer by bombarding with particles having a predetermined kinetic energy; and a step (S5) for abutting the surface-activated surface of the first inorganic material layer against the surface-activated surface of the second inorganic material layer and bonding the first polymer film and second polymer film together.
摘要:
Composite components are joined together by an amorphous thermoplastic film forming a fused thermoplastic joint between the components. Fusion of the film may be achieved at relatively low temperatures that are sufficient to cure thermoset composite components, but are below the melting point of semi-crystalline thermoplastic components.

An anchoring method of anchoring an anchoring element in a construction object is provided, where a surface of which object has at least one of pores in a surface, structures in a surface (such as an arrangement of ridges with undercut), a inhomogeneous characteristic with makes the penetration of a surface by a liquid under pressure possible, thereby creating pores filed by the liquid underneath the surface, and of a cavity. The method includes the steps of: providing a first element and a second element, the first element comprising a thermoplastic material; positioning the first element in a vicinity of said surface and/or of said cavity, respectively, and positioning the second element in contact with the first element; and causing a third element to vibrate while loading the first element with a force, thereby applying mechanical vibrations to the first element, and simultaneously loading the first element with a counter-force by the second element.
摘要:
A method for connecting a plastic workpiece to a further workpiece. The method includes inserting a pin on the plastic workpiece through a through-opening in the further workpiece and abutting the first and second workpieces against one another. A friction tool, which has a clamping ring and a friction pin, is engaged to the pin and the friction pin is rotated so that frictional heat produced by friction between the friction pin and the pin brings the pin into a plastic state. The rotating friction pin is moved parallel to the axis of rotation toward the working surface so that the pin is plastically deformed.

A method for joining pipes in which a first pipe in which at least one portion to be engaged is sunk inward to an inner circumferential surface side provided in an outer circumferential surface of an end portion of the first pipe, and a second pipe made of thermoplastic resin are joined together. The method includes: inserting an end portion of the first pipe into an end portion of the second pipe; and as a result of a component that transmits ultrasonic waves against an outer circumferential surface of the second pipe that corresponds to the portion to be engaged of the inserted first pipe, softening the second pipe by the ultrasonic waves so that an engaging portion is formed which is made to protrude into the portion to be engaged and is positioned on the inner circumferential surface of the first pipe.
摘要:
A blade, in which at least the composite base structure of the blade is manufactured in a pultrusion process by pulling fibers through at least an impregnation stage and a curing stage, the base structure is equipped with at least one wear area and the said blade is detached from a blade blank formed of a base structure and a wear area. The wear area of the blade is formed of an edge-structure part protruding outside the edge of the base structure.

The present application thus provides a composite composition comprising PTFE and zeolite. According to another aspect, the present application provides a method for making a composite article comprising bonding zeolite to PTFE. According to still yet another aspect of the present application, a method for separating components of the mixture comprising contacting the mixture with a composite composition comprising PTFE and zeolite is disclosed.
摘要:
A method is provided for joining a metallic member to a structure made of a composite matrix material. One or more surfaces of a portion of the metallic member that is to be joined to the composite matrix structure is provided with a plurality of outwardly projecting studs. The surface including the studs is brought into engagement with a portion of an uncured composite matrix material so that fibers of the composite matrix material intertwine with the studs, and the metallic member and composite structure form an assembly. The assembly is then companion cured so as to join the metallic member to the composite matrix material structure.
