The impregnation process was improved if necessary by incorporation with tools such as pressure rollers. After complete impregnation of the fibers, the pre-cure was completed at 80 ° C within 20min. After cooling, the materials were dimensionally stable, but could be converted at elevated temperature above 100 ° C after. The final curing took place at 180 ° C within 30 minutes. 4.2 incorporation into fiber material of defined shape:
- the fiber material used was 4 layers of fiberglass unidirectional covers having a basis weight of 800 g / m 2 each, which were provided in a release treated double-ended steel mold having gate and overflow stubs.
- the cavity of the mold had the dimension 100x100x2mm.
- the components A and B of the Example Formulation III were mixed in the mixing ratio shown in Table 1 as described above and tempered so that the viscosity of the resin was below 200mPas.
- the resin was pressed by means of a peristaltic pump within a few minutes in the closed at the overflow, but there pre-evacuated form, so that the fiber material was completely soaked.
