Abstract

本发明在最广义上可被定义为由片材尤其是由“NOMEX”聚合纸构成的三维轻芯，该发明能被用于在飞机制造、建筑和其他行业中所用的夹板的生产。为了改善芯的机械性能和单位重量性能，纸基底被穿孔，从而增大基底-粘合剂的接合强度，其中，粘合剂被涂敷至基底的两侧，由于在孔的位置，结合在其间的粘合剂层的连接的缘故，从而增大了基底的刚度。以一个公式来确定孔的数量及其直径。

Description

夹板芯
技术领域
我们的发明在最广义上可被定义为由片材尤其是由“NOMEX”聚合纸构成的三维轻芯，该发明能被用于在飞机制造、建筑和其他行业所用的夹板的生产。
技术背景
已知有一种折叠芯，它由合成纤维(玻璃纤维、碳纤维等)制成，合成纤维被应用到形成芯侧突脊和热压粘合剂上(RF专利no.2,057,647C1。由复合材料制造芯的方法-国际分类号为B29D9/00。-96年4月10日的公告第10条)
所描述的这种芯的主要缺点是在生产过程中需要大量的人力以及需要精密复杂的仪器来不连续地注入纤维。
已知有一种夹板芯，它(利用粘合剂)由从其两侧放入的聚合片材制成，例如由“Phenylon”聚酰胺纸制成(V.I.Khaliulin，用于生产夹层结构的技术方案，KSTU，Kazan，1999.-第168页.第40-44页.-ISBN5-7579-0295-7)。
所描述的这种芯的主要缺点是由于板结构的重量增加，这是由于使用了密度相当高的粘合剂，所使用的粘合剂的量与纸基底的量相当，以便提供芯所需的机械性能。
发明内容
我们的发明由于加强了基底-粘合剂的连接强度以及减少了所用的粘合剂的量，从而提高了由片材制成的轻芯的机械性能，这就是本发明的发明目的。
实施所要求保护的发明所获得的技术效果是提高了飞行器的功效，这是由于在飞行器中所使用的夹板单位重量(unit weight)性能被改善了的缘故。
所述的技术效果是通过以下事实来获得的，即，夹板芯呈三维结构，尤其是它由两侧涂有粘合剂的聚合纸制成，该夹板芯包括纸基底，例如利用多束式激光对这种纸基底进行穿孔，其中，孔的数量和直径满足以下条件；
n h · π · d h 2 4 > 2 · Δ b · F δ p ( 1 - ρ p ρ b )
其中：
nh是孔的数量，
dh是孔的直径，
Δb是与原型相比粘合剂层的厚度减小量，
F是芯表面积，
δp是基底层的厚度，
ρp是纸基底材料密度，
ρb是粘合剂密度。
申请人通过对现有技术的分析，表明现有技术中没有与本发明中的特征组合相类似的特征组合。因此，所要求保护的技术方案满足专利性中的“新颖性”条件。
通过在给定领域检索与所要求保护的技术方案的特征部分相同的技术特征，检索结果表明所要求保护的技术方案的特征部分的技术特征并不是来自于现有技术。从申请人尽力揭露的现有技术来看，所确定的必要技术特征对所声称的技术效果没有影响。因此，本发明所要求保护的技术方案满足专利性中的“创造性”条件。
附图说明
图1-4表示出了本发明的要素。
图1是夹板折叠芯的总体示意图；
图2表示芯坯件平面板；
图3是带有穿孔的一部分坯件；
图4是图3的A-A剖面图。
图1-4表示出了下列位置：
1是已制造好的芯，2是穿孔的坯件，3是坯料中的通孔，4是芯基底材料(聚合的“NOMEX”纸)，5是粘合剂层。
具体实施方式
夹板芯呈三维结构1，它由坯件2例如由聚合的“NOMEX，，纸制成，并沿着标志线弯折，以特定的折叠方式折叠而成。为了提高结构强度，坯件2的两侧具有涂层，该涂层是通过把例如以酚醛树脂为基础的液态的粘合剂层5涂敷至纸表面上然后经热硬化而形成。由于聚合纸对酚醛粘合剂具有相当低的粘性，芯1的坯件2在涂敷粘合剂和成形之前被穿孔，以其粘合剂层在孔3的位置粘合在其间，从而形成三维结构，该三维结构在芯结构中作为单一整体。这就可以提高芯结构的强度和刚度，或在给定强度下减小粘合剂层的总厚度，从而也就减小了粘合剂的量；最终可以改善机身中所用的具有给定芯的夹板的单位重量性能。
工业实用性
所要求保护的技术方案所获得的经济效果有：减小了粘合剂层的总厚度3，从而减小了层数，减小了用于使所涂敷的粘合剂逐层硬化所用的功率输入，从而提高了芯的生产效率。

Claims (1)
