In the present paper, we suggest a hybrid system for the determination of a possible kinematics chain of multi-brooches gearboxes which are used in drilling and threading operations of a big series of workpieces (driving blocks, gearboxes cases, etc). The system is based firstly on the representation of the multi-brooches gearbox components and assembly according to an object oriented language.

The essential role of the interface fiber/matrix in a composite material is to transmit loadings from the matrix towards the reinforcement, and then to ensure non debonding fiber/matrix during loading. Therefore one often seeks to improve this interface to have a good adherence fiber/matrix. The aim of this work is to control the parameters which can improve, for the same couple fiber/matrix, adherence at the interface and this while exploiting the surface quality of fiber. With this intention, we realized tests of indentation on composite material samples with matrix unsaturated polyester UP and carbon fibers of various roughnesses. From these tests, we noted that the rougher the carbon fibers are, the more they adhere with the matrix. The experimental results obtained were validated by finite elements method which takes as essential parameter the coefficient of friction at the interface.
