Description

一种轻质耐高温防雷击复合板材及成型方法
技术领域
本发明属于材料技术领域，尤其涉及一种轻质耐高温防雷击复合板材及成型方法。
背景技术
轻质耐高温防雷击板材对实现材料的多重功能和减轻结构重量具有明显的效果。目前，国内建筑行业广泛使用了金属防护网、火焰喷涂铝组成的防雷击板材，其重量和厚度不适用其对减重、结构尺寸的需求。国内航空领域广泛使用了碳纤维复合材料与金属网、胶膜复合成的板材或在制件表面采用火焰喷涂铝等雷电防护方式，其缺点是：一、重量大，成本高。金属铝网和胶膜的密度较大，火焰喷涂铝防护层厚度较大，导致结构重量增加较多；加之混炼工艺复杂；加温硫化需专用设备等问题，导致成本高。二、工艺复杂，易变形。需手工分别覆铺金属网和胶膜，铺设绝缘玻璃布层、火焰喷涂铝、涂封孔剂、涂地漆面漆，工序复杂，生产周期长，而且无自粘性、施工困难，且存在金属网容易起皱、变形、甚至断开等问题。三、耐蚀性与防雷击性差。因需表面处理，结合力不好，还要涂胶，易腐蚀，雷击防护效果较差。
发明内容
本发明的目的：提出一种重量轻、雷击防护性好、耐腐性与工艺性优良的轻质耐高温防雷击复合板材及成型方法，以满足航空产品的需求。
本发明的技术方案：
一种轻质耐高温防雷击复合板材，包括两层上面板和两层下面板按照[(+45,-45)/(0,90)]S的铺层比例进行均衡对称顺序铺设，所述的最外层的上面板及最外层的下面板上均设置有一层防雷击铜网胶膜，所述的防雷击铜网胶膜由铜网与胶膜复合而成。
所述的上面板和下面板均为苯并噁嗪碳纤维复合材料板。
所述单层上面板和单层下面板厚度均为0.300±0.01mm。
所述的防雷击铜网胶膜厚度为0.152±0.01mm。
所述苯并噁嗪碳纤维复合材料板的密度为1.52g/cm3。
所述的防雷击铜网胶膜密度为0.97g/cm3，
所述的防雷击铜网胶膜电阻率为1.75×10－8Ω·m。
轻质耐高温防雷击复合板材的成型方法：在最外层的上面板及最外层的下面板上铺置一层厚度为0.152mm±0.01mm的防雷击铜网胶膜，放入模具中，在 0.62MPa±0.05MPa压力作用下，升温至185℃±5℃，并保温180min～240min，最后在60℃下卸压，制成所述的轻质耐高温防雷击复合板材。
本发明的有益效果：本发明提出的一种轻质耐高温防雷击复合板材及成型方法，成型会后的复合板材重量轻，雷击防护性好,耐蚀性与工艺性优良，满足了航空产品的需求。

具体实施方式
下面结合附图对本发明作进一步的介绍，本发明所述的一种轻质耐高温防雷击复合板材，包括两层上面板1和两层下面板2按照[(+45,-45)/(0,90)]S的铺层比例进行均衡对称顺序铺设，所述的最外层的上面板1及最外层的下面板2上均设置有一层防雷击铜网胶膜3，所述的防雷击铜网胶膜3由铜网与胶膜复合而成。
所述的上面板1和下面板2均为苯并噁嗪碳纤维复合材料板，苯并噁嗪碳纤维复合材料在力学性能优异的基础上，兼具良好的防火性能，成为新型结构功能一体化材料。
作为一种新型的热固性树脂基复合材料，相比传统的热固性环氧树脂类复合材料，更低的固化收缩和放热性(固化收缩<1％)，可进一步提高试板的尺寸稳定性；同时具有更高的耐湿热性能，优良的FST(烟、火、毒)性能，可用于飞机耐高温、防火部位，如短舱、发动机整流罩等，并可室温储存(>6个月) 和输运(盒装或袋装)，有利于进一步降低成本。
所述单层的上面板1和单层下面板2厚度均为0.300±0.01mm。
所述的防雷击铜网胶膜3厚度为0.152±0.01mm，密度为0.97g/cm3，电阻率为1.75×10－8Ω·m。
所述苯并噁嗪碳纤维复合材料板的密度为1.52g/cm3。
轻质耐高温防雷击复合板材的成型方法：在最外层的上面板1及最外层的下面板2上铺置一层厚度为0.152mm±0.01mm的防雷击铜网胶膜3，放入模具中，在0.62MPa±0.05MPa压力作用下，升温至185℃±5℃，并保温180min～240min，最后在60℃下卸压，制成所述的轻质耐高温防雷击复合板材。
本发明材料结构将各向异性材料(上面板1及下面板2)和各向同性材料(防雷击铜网胶膜3)相结合，复合成一种多层材料结构，充分发挥两种材料各自的优势并弥补各自材料的缺点，实现具备轻量化、力学性能优异、耐腐蚀性好的一种多层材料结构。具体是将这种多层材料结构划分为两大部分，第一部分是由各向异性的LOCTITE BZ9704 5HS285-40AERO树脂基复合材料，具体是苯并噁嗪碳纤维复合材料板，密度为1.52g/cm3，按照[(+45,-45)/(0,90)]S均衡对称顺序铺4层构成，以最大限度的保留LOCTITE BZ9704 5HS285-40AERO材料结构的强度和刚度特性，获得最佳的力学性能，第二部分是由一种具有防雷击功能、密度为0.97g/cm3，电阻率为1.75×10－8Ω·m的LOCTITE EA 9837.1 030-040 AERO各向同性、铜网表面膜构成。第一部分LOCTITE BZ9704 5HS285-40 AERO 层板与第二部分LOCTITE EA 9837.1 030-040 AERO通过热压共固化成5层的整体结构板材。
按照图4的模拟雷击试验装置的布置形式，验证成型后的复合板材的防雷击性能，
a)轻质耐高温防雷击复合板材(试验件)四周上下两面，用金属压条夹紧固定，金属压条连接发生器回线；
b)试验电极放置于试验件中心上方。
通过对轻质耐高温防雷击复合板材(试验件)进行模拟雷击试验，大电流直接效应试验，对试验件形成雷击损伤进行测试，由冲击电流发生器(设备型号： LCG200S设备参数200kA)产生电流A和电流D,电流分量A为首次回击电流，其幅值200kA 10％，上升时间不超过50,作用积分2×106A2s±20％，试验时选用阻尼振荡波形。电流分量D为后续回击电流，其幅值为100kA±10％，上升时间不超过25μs，作用积分0.25×106A2s±20％，试验时选用阻尼振荡波形。
试验电极：
试验电极喷射型电极，如图5所示，电极距离放电位置不小于50mm，在试验电极与放电位置之间搭接一根直径不超过0.1mm的细铜丝。
进过模拟雷击试验后，苯并噁嗪碳纤维复合材料板的性能如下表所示。
Figure RE-GDA0002403878600000051
实施例1与同样厚度的金属网相比，雷击防护效果提高了约20％。
