用于制备复合组件的方法
Abstract:
用于制备复合元件的方法，包括下面的步骤：提供型芯；使所述型芯的至少一部分与聚氨酯/聚异氰脲酸酯反应混合物接触，其中在接触过程中向至少所述型芯外部施加负压p1至少一段时间。在型芯开始与聚氨酯/聚异氰脲酸酯反应混合物接触之后时间t1期满和/或在与型芯接触的聚氨酯/聚异氰脲酸酯反应混合物中达到温度T1时，向至少所述型芯外部施加正压p2。
Abstract(English):

A superatmospheric pressure p2 is applied to at least the exterior of the moulding core when a time t1 has expired after beginning of the contact of the moulding core with the polyurethane/polyisocyanurate reaction mixture and/or a temperature T1 is reached in the polyurethane/polyisocyanurate reaction mixture which makes contact with the moulding core.
