摘要:
According to the inventive method for producing a connection between a component (2) which has at least one holding element (21), and a structural element (1) (patent application 196 49 617.9), an intermediate holder (3) is formed on a surface of the structural element (1) in the connection area using an adhesive hardening casting compound (3). The intermediate holder can be joined to at least one holding element (21) of the component (2) with which it forms an active, holding connection. This is an inexpensive method for producing a connection which can be easily detached.
摘要:
The present invention relates to a method for improving both adhesion between substrate and polymer layers and the durability of such composite structure; while maintaining the malleability and preferred characteristics of the original substrate. Quite unexpectedly, the application of a layer or film upon an uncured, encapsulated base substrate which has been encapsulated by the shear thinning methods of the present invention, results in superior adhesion of multiple layers when compared to conventional layering, coating or composite manufacturing methods. The methods described herein produce multiple layer composite articles that are lighter, stronger, more flexible and utilize less material, than composite articles produced by conventional techniques. The method comprises applying an uncured, substantially solvent free, polymer composition exhibiting thixotropic or pseudoplastic characteristics, onto a base substrate having structural elements and interstices therebetween; shear thinning the polymer composition to place it into the base substrate, thereby encapsulating most of the structural elements while leaving a plurality of interstices space open; overlaying a layer or film of polymer or thermoplastic material to at least one surface of the uncured encapsulated base substrate; pressuring the layer or film into the interstices of the uncured encapsulated base substrate to form a chemical and mechanical interlocking bond between the polymer composition of the base substrate and the overlay material; optionally shaping the multi layer composite and curing the complete composite.

Die Verbindung miteinander nicht verkleb- oder verschweißbarer Kunststoffrohre (6, 7) bereitet im allgemeinen Schwierigkeiten. Um diese zu vermeiden, ist ein rohrförmiges, stabiles, aus Metall oder hochfestem Kunststoff bestehendes Zwischenstück (3) vorgesehen, das von den beiden Seiten her Abschnitte (1, 2) einer Kunststoffhülle aufnimmt, in die die Rohrleitungsenden (6, 7) passen, wobei das Zwischenstück (3) Querprofilierungen (4), vorzugsweise Ringe, aufweist, die jeweils der Werkstoff der beiden Kunststoffrohrabschnitte (1, 2) füllt.

Verfahren zum Herstellen einer Verbindungsschicht im Bereich einer Kontaktfläche zwischen einem ersten Material und einem zweiten Material, insbesondere zur Anwendung als Kaschierverfahren, dadurch gekennzeichnet, daß ein Material im Bereich der Kontaktfläche mit Schnittfasern oder Garnabschnitten beflockt wird und mit dem anderen Material, das zumindest im Bereich der Kontaktfläche plastisch oder flüssig ist, in Kontakt gebracht wird, wobei die Materialverbindung durch Erstarren mit der Einbindung der Fasern in diese Schicht erfolgt.
摘要:
A reinforcing panel and process for making the same for use in reinforcing wood structural members including laminated beams, wood I-beams, and trusses. The reinforcing panel is comprised of a plurality of synthetic fibers that are arranged parallel to one another and aligned with the longitudinal direction of the panel, and accordingly the wood structure. The panel has substantially no transverse fibers. The fibers are maintained in position by a resin encasement that completely encloses the fibers with the exception of some fibers that are closest to the surface. The surface of the reinforcing panel is treated so that those fibers closest to the surface of the panel are caused to "hair up" so that the reinforcing panel may be used with non-epoxy adhesives which are commonly used in the laminated beam industry, such as resorcinol. The reinforcing panel of the present invention is fabricated by an improved protrusion process which uses no mandrels, or woven mats and which provides for a selectable back pressure so that the fibers of the reinforcement panel are maintained in a state of tension during the resin cure, thereby: maintaining the parallel arrangement of the fibers, maintaining the longitudinal alignment of the fibers, and setting the initial strain of the fibers to decrease the initial deflection of a wood structure that is reinforced with the reinforcing panel of the present invention.

L'invention propose une pièce hybride à haute résistance comportant une première partie (1) ou partie tendre en composite à matrice organique renforcée par des fibres (6a), une seconde partie (2) ou partie dure en métal, alliage métallique ou céramique, ainsi qu'une couche de transition (3) en composite composée d'une matrice en matériau soudable à la partie (2) alors que les fibres (6b) sont le prolongement des fibres (6a) de la partie (1). La partie dure (2) est rapportée par dépôt de matière en fusion à la flamme, à l'arc électrique ou par plasma, ou bien usinée séparément et soudée sur la couche de transition (3).
摘要:
When resin pipes are connected through induction heating, the resin pipes of this invention do not form inside bulges due to air and resin expansion during the heating process. Cylindrical heater 2 made of stainless steel is placed around the joint between two resin pipes 1a, 1b made of polyvinylidene fluoride. Heater 2 is then heated by induction heating to weld the joint of resin pipes 1a, 1b. Heater 2 has a plurality of holes 2a on the cylindrical surface so that air and molten resin located between heater 2 and resin pipes 1a, 1b are released through holes 2a.
