液态复合材料模塑中的一个关键工艺步骤是通过冲压成型将二维纺织材料预成型为近净形状和可承载的纤维结构。本文介绍了在考虑粘结剂用量和成形温度的情况下，对复合材料的剪切性能、弯曲性能和摩擦性能进行的基本材料实验。此外，还考察了工艺时间对预制棒稳定性的影响。结果表明，粘结剂用量、成型温度和成型时间对预制件质量有较大影响。
A critical process step within the liquid composite moulding constitutes in the preforming of two-dimensional textile material into a near-net-shape and load-capable fibre structure by stamp forming. This paper presents fundamental material experiments on the shearing behaviour, bending properties and friction behaviour considering the binder quantity and forming temperature. In addition, the influence of the process time on the resulting stability of the preform is examined. The findings indicate that the quantity of the binder as well as the forming temperature and the process time have a great influence on the preform quality.
