METHOD AND ASSEMBLY FOR MANUFACTURING A LEAF SPRING |
摘要 |
The present invention relates to a method and an assembly for manufacturing a leaf spring from a fiber-composite material. To this end, tape material from a fiber material, which has been pre-impregnated with a matrix resin, for manufacturing a semi-finished leaf spring is wound under tension onto a winding core, wherein at least two cavities for shaping are configured on the winding core. The tape material here is pressed on by way of a contact pressure means, such that adjacent layers of the fiber material are adhesively interconnected and air pockets are removed. The semi-finished leaf spring under impingement by pressure and heat and under curing of the matrix resin is finally processed to form a leaf spring. |

1. A method for manufacturing a leaf spring from a fiber-composite material, comprising the following method steps:
providing tape material from a fibrous material, which has been pre-impregnated with a matrix resin; manufacturing a semi-finished leaf spring by winding the tape material under tension onto a winding, core, wherein at least two cavities for shaping the semi-finished leaf spring are configured on the winding core in the winding direction on the circumferential side; pressing on the tape material by way of a contact pressure means, so as to adhesively connect adjacent layers of the tape material on the winding, core, and for removing air pockets between adjacent layers of the tape material; removing the semi-finished leaf springs from the cavities of the winding core; manufacturing a leaf spring by compressing the semi-finished leaf spring while curing the matrix resin. |
