摘要:
A system and method of forming a multi-axis laminate including a production surface, a reinforcement material supply, and a resin supply, wherein the reinforcement material supply supplies a first layer of reinforcement material having a first fiber orientation to the production surface and a second layer of reinforcement material having a second fiber orientation on top of the first layer of reinforcement material, and wherein resin from the resin supply impregnates the first and the second layers of reinforcement material to form a laminate having a multi-axis fiber orientation. The reinforcement material supply may be a fiberglass material having a tri-axis fiber orientation that is layered to form a quatro-axis laminate.

A method of forming a homogenous composite pipe of unspecified length from strips of fiber reinforced thermoplastic material is disclosed. A mandrel is arranged stationary in a process direction to extend freely from a first supported end to a second end. A slip-sheath is applied about the mandrel. The thermoplastic material strips are wound about the slip-sheath. A section of the thermoplastic material strip winding is consolidated. The slip-sheath is formed from tape material which is applied longitudinally onto the mandrel surface. The slip-sheath is connected to a puller arranged downstream of the mandrel in the process direction. Consolidated pipe sections are pulled off from the second end of the mandrel in synchronization with the winding and consolidation. An assembly for carrying out the method.

An apparatus for producing an elastomeric nonwoven laminate including a plurality of elastomeric strands joined to a nonwoven web in a controlled distribution is provided. The apparatus includes an extruder for extruding a plurality of elastomeric strands onto a cooled surface of a rotating drum, which transports the strands in parallel alignment to a nip formed between two rollers rotating about parallel axis. The drum transfers the plurality of strands to the nip in a controlled distribution where it is bonded with the nonwoven. The apparatus also includes elements which automate the apparatus for creating the elastomeric nonwoven laminate.

Method for bonding together up to three layers in a film, which may be made of layers of different materials. The method includes unwinding from pay-off units layers of the film and guiding them into a spreader/applicator units designed to apply an adhesive material to one side of the layers and feeding them to a bonding zone (1), bonding together the layers in the bonding zone, by winding them over a first bonding calender (18), along a contact arc on the surface of said calender. The method is characterized by determining the breadth of said contact arc by rotating a nip onto which the presser roller (19) is mounted, so as to vary the position of the point of contact between a presser roller (19) and the surface of said bonding calender (18). The bonded film is then taken up.
