Description
技术领域
本发明涉及蜂窝复合板材技术,特别涉及一种轻质高强、隔热、隔音、耐腐蚀、耐冲击蜂窝夹层结构复合材料的制备方法。
背景技术
交通工具在给人们的出行带来方便的同时,也产生了油耗、安全和环保三大问题。不管是汽车、轨道交通,还是轮船、飞机,在国家节能减排的大背景下,结构、材料轻量化是最有效的手段和方法。
PP蜂窝板具有轻质高强、耐水、隔热、隔音、热塑再变型和耐冲击等特点,特别适合制作各种复合夹芯。目前,市面上的PP蜂窝夹芯板材多为PP蜂窝与玻璃纤维毡增强热塑性PP复合板蒙皮的复合,虽然韧性很好,但是强度不足,且易发生翘曲和变形。还有一部分夹芯板是PP蜂窝板与玻璃钢蒙皮复合,但是加工工艺较繁琐,无法一体成型。而且以上两种夹层结构均以纯PP蜂窝为夹芯层,存在耐温性差,层间剪切强度不足。
由于PP材质化学结构惰性,高结晶度,决定了此类塑料蜂窝板的低表面能、非极性和弱界面层特性,很难按常规的方法实现与碳纤维复合材料蒙皮的粘接。即使经过特殊的表面处理,不仅增加成本,而且由于PP材料的热变形温度在90℃左右,低于碳纤维增强环氧树脂基预浸料常规的成型温度120~150℃,无法满足碳纤维增强/环氧泡沫填充PP蜂窝夹芯板材一体成型的工艺要求,使得这种结构的应用受到限制。
环氧树脂泡沫同时具备泡沫材料的优点和环氧树脂固化物的特性,因而具有粘接性好、低密度、强度和损伤容限高、耐温好、收缩率小等优点。环氧树脂泡沫也可以直接作为碳纤维增强复合材料蒙皮的夹芯,但是环氧树脂泡沫属于开孔结构,容易吸水,不仅密度变大,而且耐温、耐蠕变等性能下降明显。
因此,在PP蜂窝板内填充大发泡倍率环氧树脂泡沫,然后与碳纤维增强环氧树脂预浸料叠层固化的碳纤维增强/环氧泡沫填充PP蜂窝夹芯复合板材不但是最佳的组合结构,而且是性能最佳的组合材料。
发明内容
本发明的一个目的是解决至少上述问题和/或缺陷,并提供至少后面将说明的优点。
本发明还有一个目的是解决PP蜂窝板与碳纤维复合材料蒙皮的粘接困难的技术问题,同时解决PP蜂窝板在较高温度下容易软化变形的技术问题。

为了实现本发明这些目的和其它优点,本发明提供了一种pp蜂窝夹芯复合板材,其包括:pp蜂窝板、填充在pp蜂窝板孔内的环氧树脂泡沫以及分别铺设于pp蜂窝板上、下表面的碳纤维增强环氧树脂复合材料蒙皮;所述碳纤维增强环氧树脂复合材料蒙皮与pp蜂窝板之间通过环氧树脂胶膜粘接固定。

S4、取出环氧树脂泡沫填充的PP蜂窝板,进行切边修整;
S5、上蒙皮预浸料叠层,然后依次设置环氧树脂胶膜和环氧树脂泡沫填充PP蜂窝板,再依次设置环氧树脂胶膜和下蒙皮预浸料叠层,层叠完后,放入涂有脱模剂的模具内;
S6、液压机闭合模具,加压,将模具先升温,然后保温,再降温,得到初产品;
