摘要/Abstract

摘要： 针对连续纤维增强树脂基复合材料,设计了宏观尺度上的高通量制备技术平台和典型工艺的实现方案。高通量制备技术平台的设计结合了复合材料真空热压工艺和先进预浸料拉挤工艺连续制备复合材料的特点,调整平台的压力和温度即可连续制备大批量的不同工艺流程的复合材料样品。与传统热压罐工艺相比,平台制备不同工艺的样品周期能显著缩短。与传统的连续升温相比,平台的台阶式升温过程使得厚度方向的温度梯度略有减小,升温方式对复合材料固化度的演变过程影响很小。

Abstract: High-throughput preparation technology platform on a macro scale for continuous fiber reinforced composites was designed. Realization program of a typical process with this platform was also planned. The design feature of the high-throughput preparation technology platform was the combination of vacuum assisted hot pressing process and advanced prepreg pultrusion process. Composite samples in large quantities can be formed with different process parameters by adjusting pressure and temperature of the platform. The period of preparing composites with different process parameters using the platform is much shorter than using traditional autoclave molding. Heating step by step in the platform makes the temperature gradient along the thickness slightly less than the traditional continuous heating mode. Heating method has little influence on the curing degree evolution of the composite material.

Key words: high-throughput preparation, composites, continuous fiber reinforced resin
