Automated fiber placement system and associated method
Disclosed herein is an automated fiber placement system that comprises a robot, an end effector, and a creel assembly that is coupled to the robot and movable with the robot. The creel assembly comprises a spool of a tow and a tow tensioner. The tow tensioner comprises an arm assembly that is pivotable toward and away from a tow direction between a forward position and a rearward position, inclusive, and configured to secure the tow from the spool as the tow unwinds from the spool and moves in the tow direction. The tow tensioner also comprises a biasing member that is coupled to the arm assembly and configured to bias the arm assembly into a neutral position between the forward position and the rearward position. The tow tensioner additionally comprises a potentiometer that is coupled to the arm assembly and configured to detect a position of the arm assembly.
Filament winding apparatus and filament winding method
A winding section of a filament winding apparatus winds a fiber bundle around a filament-wound member. A tension acquisition part acquires a detected winding-tension value. A supply-speed acquisition part acquires a detected supply-speed value. A storage part stores correlation information in which an allowable determination range of winding tension is set in relation to the supply speed. A determination part determines whether the winding of the fiber bundle is successful or unsuccessful by comparing detected-value information, including the detected winding-tension value and the detected supply-speed value associated with each other, with the correlation information.

Method for producing a casing made of a composite material for an aircraft turbine engine, the casing having an annular shape and including an annular fibrous preform formed by winding a fibrous cloth soaked in a polymer matrix, the method including the steps of: a) positioning an edge of the cloth on a molding drum, this cloth having a generally elongate shape and the edge being located at a first longitudinal end of the cloth, b) winding the cloth on the drum, over at least one rotation, so as to obtain the preform wound around the drum, c) molding of the preform and hardening of the resin which is injected into the preform or pre-impregnated on the preform, wherein the method includes, before step a), a step i) of mounting a removable stop on the drum, and in that step a) includes abutting the edge against this stop.
Method and device for manufacturing a pipe shell from an insulating material
The invention relates to a method and a device for manufacturing a pipe shell from an insulating material by means of which the cycle times can be further reduced while the quality of the pipe shell is simultaneously improved, by at least one web (29) of the insulating material which is provided with a binding agent being wound around a core (19) by means of at least two opposing belts (12, 13) which wrap around the core (19) partially. The method steps are characterized in that the at least one wound-up web (32) of insulating material is removed in a radial direction of the core (19) which is, however, not opposite to the direction in which the at least one web (29) of insulating material was fed by the one belt (12), especially by the wound-up web (32) being discharged through the same belt (12).
