Abstract: A device for fabricating a composite material part by injecting resin into a fiber structure. The device includes: a first die presenting two adjacent support surfaces defining a reentrant angle between them; at least one chock with a wedge-shaped portion configured to press the fiber structure into the angle; and a second die movable relative to the first die, the first and second dies being configured to clamp on the fiber structure and the chock. The chock is connected to the second die by at least one link, the link being hinged relative to the second die and relative to the chock to guide the wedge-shaped portion towards the angle to press the fiber structure into the angle when the second die approaches the first die.

Abstract: A machine for weaving or winding a fiber preform on a mandrel having an axis of rotation that is substantially horizontal and that serves to receive the preform, the machine having a plurality of cameras pointing towards the underside of the fiber preform in order to scan the hidden face of the fiber preform and acquire images of the hidden face; an image analysis module for processing these images of the hidden face of the fiber preform in a plurality of adjacent scan windows, and for extracting weaving patterns therefrom and comparing them with reference weaving patterns previously stored in the module; a motor for driving the mandrel in rotation about its axis of rotation; and a control unit for stopping rotation of the mandrel if the result of the comparison reveals a difference of appearance between the two weaving patterns.
