Verfahren zur Herstellung einer aus monolithischem Verbundwerkstoff hergestellten Pleuelstange durch Auflegen von vorimprägnierten Fasern auf einer entfernbaren Form und dadurch erhaltene Pleuelstange |
摘要 |
- The subject of the invention is a method for manufacturing a connecting rod from monolithic composite material by placing pre-impregnated fibres on an extractable mandrel, characterised in that it comprises the following successive steps: producing a meltable mandrel (7), of shape corresponding to that of the connecting rod, on a central rigid shaft (6); winding and/or laying down in contact with each other the said pre-impregnated fibres, according to a predetermined number of layers and a predetermined inclination of the fibres with respect to the longitudinal axis of the mandrel (7); polymerising, with application of a homogeneous compacting pressure over the entire external surface of the assembly thus obtained; and then the final operations of removing the said mandrel (7) and of machining the connecting rod to the required dimensions. - Application to the manufacture of connecting rods, especially made from monolithic composite material. <IMAGE> |
