Description

一种复合材料天线透波罩及宽频带电厚度控制及制造方法
技术领域
本发明涉及天线领域,尤其是一种天线透波罩的控制及其制造方法,可用于卫星通信、电子测控、雷达探测等领域应用的复合材料天线透波罩制造,特别适合Ku宽频带使用条件下,对电厚度均匀性要求较高的复合材料天线透波罩的设计及制造。
背景技术
雷达天线透波罩是天线系统的主要组成部分,主要作用是保护天线及相关联的电子设备免受来自环境的影响,减小电磁能量的失真,同时保证天线性能和结构稳定。天线透波罩对电磁波的吸收、反射、折射、散射,都会引起电磁波的传输损耗、插入相位差变化,给雷达系统带来不良影响,造成通信距离及雷达探测距离的降低、瞄准误差的增加,对于宽频带雷达天线的性能影响更为明显。天线透波罩在通过电磁波时幅度和相位的一致性越好,即电厚度一致性越好,实际应用中对天线性能的影响就越小。
要求较高的天线透波罩做法通常采用低介电玻璃纤维预浸料或石英纤维预浸料热压罐成型制作,利用预浸料下料机下料、激光投影对位的方法进行预浸料铺层,但在没有下料机、激光投影仪设备的情况下,通过操作人员做到精准下料、精准对位铺层就较为困难。
发明内容
为了克服现有技术的不足,本发明提供一种复合材料天线透波罩及宽频带电厚度控制及制造方法。本发明涉及的天线透波罩用于支撑副反射器,具有透波、防护、增加强度以及减小风阻的功能,锥面成型的均匀性、稳定性决定天线透波罩性能的优良,直接影响天线透波罩的电厚度一致性。在没有下料机、激光投影仪设备的情况下,本发明提供一种利用设计制作的工装、不同阶段最佳固化工艺参数,实现天线透波罩在锥面空间铺层和胶黏剂均匀分布的方法,最终使天线透波罩在宽频带使用条件下电厚度(幅度、相位)均匀性达到设计要求。
本发明解决其技术问题所采用的技术方案是:
一种复合材料天线透波罩,在宽频带下使用,包含A夹层结构、筒形钛合金嵌件、26个嵌件和法兰,A夹层结构为锥形,锥形的下沿带有内翻边法兰,筒形钛合金嵌件位于天线透波罩的顶部,26个嵌件均布在法兰周边,天线透波罩在模具上成型A夹层结构,并用载体胶膜和发泡胶将筒形钛合金嵌件与A夹层结构粘接成一体,用发泡胶填充26个嵌件一周形成的法兰。
所述A夹层结构包括内蒙皮、芳纶纸蜂窝夹芯和外蒙皮,在模具上通过载体胶膜将内蒙皮和外蒙皮粘接在芳纶纸蜂窝夹芯的两侧,通过热压罐固化形成A夹层结构;内蒙皮和外蒙皮采用介电常数低于4.3的玻璃纤维预浸料通过热压罐固化成型制作。
所述内蒙皮和外蒙皮均为四层玻璃纤维预浸料铺层,铺贴的预浸料采用蒙皮0°下料样板和蒙皮90°下料样板分别裁切出需要的预浸料数量,按照0°/90°/0°/90°纤维方向对接铺贴,每块预浸料之间的接缝采用对接,预浸料之间不留接缝缝隙。
本发明还提供一种复合材料天线透波罩的宽频带电厚度控制及制造方法,具体步骤为:
所述内蒙皮和外蒙皮的铺层采用FiberSIM软件进行铺层仿真,得到蒙皮最佳分块数为天线透波罩锥面的1/4,最佳是指在玻璃纤维预浸料幅宽1m限制下,天线透波罩模具锥面上铺贴的预浸料接缝最少,将铺层仿真结果转换成下料样板CAD图,根据下料样板CAD图,将下料样板设计制作成内轮廓样板,分为蒙皮0°下料样板和蒙皮90°下料样板,蒙皮0°下料样板和蒙皮90°下料样板是长度和预浸料幅宽1m一致,使用样板裁切预浸料时,样板四周的方框与预浸料边沿对齐,裁切的0°和90°预浸料角度符合纤维角度要求,可以防止下料过程中预浸料纤维方向角度的误差对天线透波罩力学性能及均匀性的影响。
所述铺层按照4层蒙皮铺贴,每层蒙皮由4块预浸料在模具上拼接铺贴,为保证16块预浸料接缝在锥面上均匀分布,每层预浸料拼接缝错开22.5°进行铺层(360°÷4层÷4块=22.5°),第一层的4块预浸料铺层时每块预浸料边沿对准中心角度对位工装和法兰外围角度对位工装上的4个刻线1,第二层的4块预浸料铺层时每块预浸料边沿对准中心角度对位工装和法兰外围角度对位工装上的4个刻线2,第三层对准中心角度对位工装和法兰外围角度对位工装上的4个刻线3,第四层对准中心角度对位工装和法兰外围角度对位工装上的4个刻线4,即可精确控制蒙皮错缝角度,保证每块预浸料接缝在锥面上均匀22.5°分布,从铺层上减小铺层误差的随机性,从而控制天线透波罩电厚度的均匀性。
所述中心角度对位工装和法兰外围角度对位工装均为圆形,在圆周边沿环绕一周均匀设有16个刻线,每两个刻线之间的中心角度为22.5°。
所述天线透波罩需进行四次热压罐固化成型,四次成型采用不同的固化参数,固化内蒙皮、外蒙皮时采取1℃/min的升温/降温速率和300kpa的成型压力,保证蒙皮厚度均匀性;连接蒙皮与芳纶蜂窝芯材的载体胶膜固化时,考虑芳纶纸蜂窝的抗压强度,采取150kpa的成型压力;发泡胶和嵌件粘接固化采取150kpa的成型压力和2.5℃/min的升降/温速率。不同阶段采用不同的固化工艺参数,从胶黏剂均匀分布上控制天线透波罩电厚度的均匀性。
通过嵌件定位工装确定嵌件位置,用SY-P14胶固定26个嵌件,嵌件周围的芳纶纸蜂窝采用J-47D发泡胶填充,成为天线透波罩环状补强结构的法兰。
本发明的有益效果在于在缺少下料机、激光投影仪设备的情况下,本发明通过设计制作下料工装,角度对位工装,精准下料、精准在锥面上对位铺贴预浸料,减小制造缺陷和铺层误差的随机性,保证预浸料在锥面空间上铺层的均匀性;预浸料、载体胶膜、发泡胶等固化采用不同的固化工艺参数和升降温速率,保证胶黏剂在锥面上均匀分布,最终使天线透波罩在宽频带使用条件下电厚度(幅度、相位)均匀性达到设计要求。
对于在宽频带使用状态下,天线透波罩的电厚度均匀性要求较高的情况下,天线透波罩通常采用低介电玻璃纤维预浸料或石英纤维预浸料热压罐成型,在预浸料下料时,利用预浸料下料机精确下料,在模具上铺层时采用激光投影对位的方法进行预浸料角度精确对位铺层的方法,来保证预浸料在锥面空间上铺层的均匀性。但在没有下料机、激光投影仪设备的情况下,通过操作人员手工下料做到精准下料、精准对位铺层就较为困难,本发明通过FiberSIM软件仿真得到最佳分片图形,转换成CAD图形,制作内轮廓下料工装,角度对位工装减小制造缺陷和铺层误差的随机性,保证预浸料在锥面空间上铺层的均匀性。
本发明制作的角度对位工装包含中心角度对位工装和法兰外围角度对位工装,通过两个工装的组合搭配使用,解决铺贴内、外蒙皮的预浸料在锥面上接缝的均匀性分布问题。
本发明制作的两种内轮廓下料样板避免了操作人员下料时对预浸料纤维角度的误差,预浸料幅宽为1m,下料样板宽度1m,只要样板四周与预浸料的边沿对齐,裁切的预浸料角度就符合纤维角度要求,避免预浸料角度误差带来的固化后的天线透波罩扭曲形变问题。
本发明根据预浸料、胶膜、发泡胶固化的不同特点,采用不同的固化工艺参数、不同的升降温速率,保证胶黏剂在锥面上分布的均匀性,避免胶黏剂分布不匀带来的电厚度不均匀,最终影响雷达天线的性能。
本发明采用FiberSIM复合材料软件仿真得到接缝最少的最佳铺层方法,并利用软件仿真结果制作蒙皮的内轮廓下料样板;采用角度对位工装精确控制内、外蒙皮铺层接缝,保证内、外蒙皮空间分布上的均匀性;采用适合的固化成型参数分别成型内蒙皮、蜂窝粘接、嵌块及发泡胶、外蒙皮成型,保证胶黏剂在锥面天线透波罩上分布的均匀性。采用上述方法制作的天线透波罩,电厚度均匀性好,幅度一致性可以控制在±0.1dB以内,相位一致性可以控制在±3°以内,优于设计要求。

所述A夹层结构包括内蒙皮、芳纶纸蜂窝夹芯和外蒙皮,在模具上通过载体胶膜将内蒙皮和外蒙皮粘接在芳纶纸蜂窝夹芯的两侧,通过热压罐固化形成A夹层结构;内蒙皮和外蒙皮采用介电常数低于4.3的玻璃纤维预浸料通过热压罐固化成型制作。
所述内蒙皮和外蒙皮均为四层玻璃纤维预浸料铺层,铺贴的预浸料采用蒙皮0°下料样板和蒙皮90°下料样板分别裁切出需要的预浸料数量,按照0°/90°/0°/90°纤维方向对接铺贴,每块预浸料之间的接缝采用对接,预浸料之间不留接缝缝隙。
本发明还提供一种复合材料天线透波罩的宽频带电厚度均匀控制及其制造方法,具体步骤为:
所述内蒙皮和外蒙皮的铺层采用FiberSIM软件进行铺层仿真,得到蒙皮最佳分块数为天线透波罩锥面的1/4,最佳是指在玻璃纤维预浸料幅宽1m限制下,天线透波罩模具锥面上铺贴的预浸料接缝最少,将铺层仿真结果转换成下料样板CAD图,根据下料样板CAD图,将下料样板设计制作成内轮廓样板,分为蒙皮0°下料样板和蒙皮90°下料样板,蒙皮0°下料样板和蒙皮90°下料样板是长度和预浸料幅宽1m一致,使用样板裁切预浸料时,样板四周的方框与预浸料边沿对齐,裁切的0°和90°预浸料角度符合纤维角度要求,可以防止下料过程中预浸料纤维方向角度的误差对天线透波罩力学性能及均匀性的影响。
所述铺层按照4层蒙皮铺贴,每层蒙皮由4块预浸料在模具上拼接铺贴,为保证16块预浸料接缝在锥面上均匀分布,每层预浸料拼接缝错开22.5°进行铺层(360°÷4层÷4块=22.5°),第一层的4块预浸料铺层时每块预浸料边沿对准中心角度对位工装和法兰外围角度对位工装上的4个刻线1,第二层的4块预浸料铺层时每块预浸料边沿对准中心角度对位工装和法兰外围角度对位工装上的4个刻线2,第三层对准中心角度对位工装和法兰外围角度对位工装上的4个刻线3,第四层对准中心角度对位工装和法兰外围角度对位工装上的4个刻线4,即可精确控制蒙皮错缝角度,保证每块预浸料接缝在锥面上均匀22.5°分布,从铺层上减小铺层误差的随机性,从而控制天线透波罩电厚度的均匀性。
所述中心角度对位工装和法兰外围角度对位工装均为圆形,在圆周边沿环绕一周均匀设有16个刻线,每两个刻线之间的中心角度为22.5°。
所述天线透波罩需进行四次热压罐固化成型,四次成型采用不同的固化参数,固化内蒙皮、外蒙皮时采取1℃/min的升温/降温速率和300kpa的成型压力,保证蒙皮厚度均匀性;连接蒙皮与芳纶蜂窝芯材的载体胶膜固化时,考虑芳纶纸蜂窝的抗压强度,采取150kpa的成型压力;发泡胶和嵌件粘接固化采取150kpa的成型压力和2.5℃/min的升降/温速率。不同阶段采用不同的固化工艺参数,从胶黏剂均匀分布上控制天线透波罩电厚度的均匀性。
通过嵌件定位工装确定嵌件位置,用SY-P14胶固定26个嵌件,嵌件周围的芳纶纸蜂窝采用J-47D发泡胶填充,成为天线透波罩环状补强结构的法兰。

(4)用蜂窝下料样板裁切4块芳纶纸蜂窝,用蒙皮下料样板裁切4块J-95载体胶膜,先在蒙皮上对接平整铺贴胶膜,再对接铺贴蜂窝/辅料,蜂窝对接缝隙处铺贴一层J-95载体胶膜,按照胶膜工艺参数热压罐固化粘接蜂窝,固化时间为7~8小时;
(5)通过嵌件定位工装确定26个嵌件位置,用SY-P14胶固定26个嵌件,嵌件周围的芳纶纸蜂窝采用J-47D发泡胶填充,按照发泡胶工艺参数热压罐固化发泡胶,固化时间为7~8小时;
