Abstract
The present invention relates to a process for making a connecting rod for controlling or transmitting efforts, comprising a rod provided at at least one of its ends with a connecting member, wherein a tubular element is firstly made of high strength fibers impregnated with polymerizable resin, said end is then flattened so that it is obturated, after which the resin impregnating said element is polymerized, then said connecting member is arranged in the hardened, flattened part of said element. The invention is more particularly applicable to the manufacture of connecting rods for controlling and transmitting efforts, particularly for aircraft, helicopters, etc. . . .
Claims8
A process for making a connecting rod provided with a connecting member on at least one of its ends, comprising the steps of:
- forming a tubular element by winding high strength fibers impregnated with polymerizable resin on a light, rigid, deformable, cylindrical solid mandrel having a length not greater than the length of said connecting rod, said mandrel having, adjacent at least one of its ends, a section of smaller diameter than the remainder thereof, said winding extending over said section;
- flattening said tube at said one end of said mandrel so that is is obturated,
- polymerizing said resin impregnating said fibers in the presence of said mandrel to form a hardened tubular element having a flattened end;
- and
- arranging said connecting member in said hardened, flattened end of said tubular element.
