树脂基复合材料模具用预浸料及优势分析

Study on The Advantage of Prepreg Used in the Resin Matrix Composite Mold

模具是复合材料成型的基础要素,对复合材料制品的尺寸、内外质量及力学性能都起着极为重要的作用。在众多复合材料模具类型中由于复合材料模具热膨胀系数与复材制品相当而得到轨道交通、航空航天、船舶、汽车、体育器材等领域的广泛关注和普遍应用。在制备先进复合材料模具的过程中,使用的是各种高性能预浸料,本文对模具用预浸料进行了分类和说明,可供从业人员参考。

The mold is the basic element of composite material molding,and plays an extremely important role in the size,internal and external quality and mechanical properties of composite material products.Among all the molds,the composite molds has been widely concerned and used in rail transportation,aerospace,ships,automobiles,sports equipment and other fields,for the thermal expansion coefficient of composite molds is comparable to that of composite materials.In the process of preparing advanced composite material molds,various high-performance prepregs are used.In this paper,the prepregs for molds are classified and explained for the reference of practitioners.
