A process for the simultaneous production of a plurality of leaf springs from a fiber composite material

2012 
A process for the production of leaf springs (5a ', 5b', 5c ', 5d') consists of a fiber composite material, in which firstly to build a not yet hardened crude leaf spring (5a, 5b, 5c, 5d) impregnated plurality of layers of synthetic resin or impregnated fibers are laid over each other, in which then a plurality of these raw leaf springs (5a, 5b, 5c, 5d) with different axial lengths (L) are placed vertically one above the other, wherein in each case a release film (4a, 4b, 4c, 4d, 4e) between is placed the raw leaf springs (5c, 5d 5a, 5b), wherein the longest crude leaf spring (5a) is first deposited, that then the next shorter crude leaf spring (5b) follows, and finally the shortest crude leaf spring (5d) at the same time as the last on the stack top (10) is arranged the raw leaf springs (5b, 5c, 5a), and in which these raw leaf springs (5a, 5b, 5c, 5d) in a molding press (1) (under the action of a predetermined time and temperature profile Pressdruck- to manufacture leaf springs 5a ', 5b ', 5c' are cured 5d ').
