Description

高强度弹壳的加工方法
技术领域
本发明涉及一种弹壳，特别涉及一种高强度弹壳的加工方法。
背景技术
弹壳是枪弹或炮弹的基础部件，其作用是用来连接弹丸、底火和装发射药，使之成为一个整体，以保证全弹在弹膛内确实定位，防止发射药受外界条件的影响以及射击时阻止火药气体从枪膛尾部泄出和直接烧蚀弹膛。
传统的弹壳主要由三层材料层叠而成，其分别为玻璃纤维内层、中间层及外层。皆采用玻璃纤维作为内、中、外层。其阻燃性及耐高温性差，并且内、中、外层的分布方式分为为垂直或纵向缠绕成型。呈垂直及纵向交错后其表面存在较大的镂空，该镂空处的受力强度较弱，受到外力冲击时，镂空处在实施水压测试时，抗压力较弱，该处在使用过程中容易出现破损，导致整个弹壳无法使用或在使用过程中出现爆裂的情况。
发明内容
针对现有技术存在的不足，本发明提供了一种抗压力大、耐高温、阻燃性好的高强度弹壳的加工方法。
为实现上述目的，本发明提供了如下技术方案：一种高强度弹壳
的加工方法，其特征在于，步骤如下：a、选用玻璃纤维作为内层基体及外层的制作材料，碳纤维作为中间层制作材料；b、将作为制作材料的玻璃纤维及碳纤维表面分别涂设树脂；c、将步骤b中涂设有树脂的玻璃纤维呈垂直或纵向方式缠绕制作内层基体；d、将步骤b中涂设有树脂的碳纤维套设于步骤c的内层基体外，形成中间支撑层，且套设时呈多层网状方式排布，多层网状排布后将其上的网孔缩小或完全覆盖；e、在步骤d的中间支撑层外套设由玻璃纤维呈垂直或纵向方式缠绕制作的外层。f、将步骤e中完成层叠的内层基体、中间支撑层及外层放置于烘箱中实施烘干，烘干后由烘箱中取出，待其冷却后形成成品。
采用上述技术方案，选用碳纤维作为中间支撑层，其本身具有较
好的阻燃性，通过在玻璃纤维及碳纤维表面涂设树脂后，树脂具有耐高温的特性，因此可提高弹壳的耐高温性，同事使内层基体、中间支撑层以及外层的胶联性更好，不会出现脱落的情况。中间支撑层的制作方式为多层网状排布，从而将网孔缩小或完全覆盖，若干层的相互层叠及支撑，促使中间层具有较好的支撑力，同时网孔小或完全没有，使其受力面所能承受的压力更大，从而提高了本发明的抗压强度。
本发明进一步设置为：步骤e中位于烘箱内的烘干温度为120℃
—220℃；烘干时间为6h—8h。
采用上述技术方案，采用该特定的温度及时间可使各基体之间的粘合度更好，不易脱落，同时也更进一步的提高了弹壳的受力强度，延长了其使用寿命
本发明更进一步设置为：步骤d中碳纤维的层数为至少两层。
采用上述技术方案，这样设置支撑力更好。
下面结合附图对本发明作进一步描述。
附图说明
图1为本发明实施例中加工出的弹壳的结构示意图。
具体实施方式
如图1所示的一种高强度弹壳的加工方法，步骤如下：a、选用
玻璃纤维作为内层基体1及外层2的制作材料，碳纤维作为中间层制作材料；b、将作为制作材料的玻璃纤维及碳纤维表面分别涂设树脂；c、将步骤b中涂设有树脂的玻璃纤维呈垂直或纵向方式缠绕制作内层基体1；d、将步骤b中涂设有树脂的碳纤维套设于步骤c的内层基体1外，形成中间支撑层3，且套设时呈多层网状方式排布，多层网状排布后将其上的网孔缩小或完全覆盖；e、在步骤d的中间支撑层3外套设由玻璃纤维呈垂直或纵向方式缠绕制作的外层2。f、将步骤e中完成层叠的内层基体1、中间支撑层3及外层2放置于烘箱中实施烘干，烘干后由烘箱中取出，待其冷却后形成成品。上述方案选用碳纤维作为中间支撑层3，其本身具有较好的阻燃性，通过在玻璃纤维及碳纤维表面涂设树脂后，树脂具有耐高温的特性，因此可提高弹壳的耐高温性，同事使内层基体1、中间支撑层3以及外层2的胶联性更好，不会出现脱落的情况。中间支撑层3的制作方式为多层网状排布，从而将网孔缩小或完全覆盖，若干层的相互层叠及支撑，促使中间层具有较好的支撑力，同时网孔小或完全没有，使其受力面所能承受的压力更大，从而提高了本发明的抗压强度。
在本发明实施例中，步骤e中位于烘箱内的烘干温度为120℃—220℃；烘干时间为6h—8h。步骤d中碳纤维的层数为至少两层。
由本发明制作而成的弹壳在实施水压测试时，其可承受50MaP—70Map的压力，可承受250℃—280℃的高温。
