相关申请的交叉引用
本申请要求2016年4月28日在韩国知识产权局提交的韩国专利申请第10-2016-0052105号的优先权和权益,该申请的全部内容并入本文以供参考。
技术领域
本发明涉及一种具有插入成型接合钢的复合材料,更具体地,涉及一种增强复合材料与接合钢之间的剪切强度的插入成型接合钢。
背景技术
通常,车辆的发展要求车辆在轻质的同时具有高强度。因此,相比于钢材料,由重量较轻的材料比如铝或复合材料形成的车身具有优异的刚性,且设计自由度高。由于如上所述将新材料比如铝或复合材料用于车身,因此需要组合不同材料,且基于不同材料的组合进行了研究开发。特别是,涉及到焊接性能或腐蚀性,将不同材料进行组合存在缺点。因此,很大程度上使用机械的接合方法,但是,这没有产生所需的刚性。
例如,通过在复合材料中形成开孔,实现用于连接复合材料和钢材料的结构。通过穿过开孔的螺栓连接,将复合材料紧固至钢材料,因此该结构不适合大规模生产,因为装配过程缓慢。为了增强如上所述的复合材料与钢材料之间连接的刚性,将连接部件插入到复合材料和钢材料之间。然而,由于连接部件没有适当地或牢固地接合到复合材料,连接部件的插入导致开裂的出现。
上述在该背景技术部分公开的信息仅用于增强对本发明背景的理解,因此其可能含有不构成在该国本领域普通技术人员已经知晓的现有技术的信息。
发明内容
本发明提供一种具有插入成型接合钢的复合材料,通过形成接合钢而改进复合材料与接合钢之间的剪切强度。包括凸缘的接合钢可通过插入成型而设置在纤维之间,并引入树脂。
本发明的示例性实施方式提供一种具有插入成型接合钢的复合材料,其可以包括在形成并插入在多个纤维之间的接合钢上各自沿一个方向具有凸缘的多个去毛边开孔,树脂可以被引入到纤维之间去毛边开孔内和凸缘外部。可以形成剪切强度增强部分,其增强复合材料与接合钢之间的剪切强度。
此外,在一些示例性实施方式中,剪切强度增强部分的至少一部分的厚度可以大于复合材料的厚度和凸缘的高度。凸缘可以沿着去毛边开孔外周在一个方向上形成,并且可以在与接合钢横截面垂直的方向上形成。接合钢可以具有焊接端,所述的焊接端沿着未插入成型于复合材料中的外部尖端形成。在其他的示例性实施方式中,去毛边开孔可以形成为圆形开孔。
根据本发明的示例性实施方式,剪切强度增强部分可以通过在纤维之间引入树脂而形成。沿一个方向具有凸缘的接合钢可以通过在纤维之间插入成型而形成,因此,可以增加纤维的厚度,结果复合材料与接合钢之间的剪切强度可以得到改进。此外,通过本发明示例性实施方式获得的或预期的其他效果,将直接地或隐含的公开于本发明示例性实施方式的详细描述中。换言之,根据本发明示例性实施方式预期的各种效果将公开在下述的详细描述中。

具体实施方式
在后文中,参照附图描述本发明的示例性实施方式。然而,下面示出的附图和后面的描述涉及各个示例性实施方式中的一个示例性实施方式,以便有效地解释本发明的特征。尽管本发明将结合示例性实施方式进行描述,但应当理解,本说明书无意于将本发明局限于这些示例性实施方式。相反,本发明不仅要涵盖这些示例性实施方式,还要涵盖各种替换方式、变化方式、等同方式和其它实施方式,其均可以包括在所附权利要求限定的本发明的精神和范围之内。
本文中使用的术语仅出于描述具体实施方式的目的,而不意在限制本发明。如本文所使用的,单数形式“一个、一种”和“该”也意在包括复数形式,除非上下文中清楚指明。还应进一步理解的是,在说明书中使用的术语“包括”和/或“包含”是指存在所述特征、整体、步骤、操作、元件和/或组件,但是不排除存在或添加一个或多个其它特征、整体、步骤、操作、元件、组件和/或它们的组。如本文所使用的,术语“和/或”包括一个或多个相关所列项目的任一组合和所有组合。例如,为了使本发明的描述清楚,无关的部件没有显示,且为了清晰,层和区域的厚度被放大。进一步地,如果说一层在另一层或基底“上”,该层可以直接在另一层或基底上,或可以在其间设置第三层。
应理解,本文使用的术语“车辆”或“车辆的”或其它类似术语包括通常的机动车辆,比如,包括多功能运动车(SUV)、公共汽车、卡车、各种商务车的客车,包括各种船只和船舶的水运工具,飞行器等等,并且包括混合动力车、电动车、燃油插入式混合电动车、氢动力车和其它代用燃料车(例如,来源于石油以外的资源的燃料)。
图1是根据本发明的示例性实施方式的具有插入成型接合钢的复合材料的示例性剖面图。图2是根据本发明的示例性实施方式的具有插入成型接合钢的复合材料的示例性剖面图。参照图1和图2,根据本发明的示例性实施方式的具有插入成型接合钢的复合材料(在后文中,被称为复合材料)可以被应用来通过插入成型接合钢10而牢固地与车身构件1接合。
复合材料可以在接合钢10上包括多个去毛边开孔13,其沿一个方向具有凸缘11。特别是,凸缘11可以沿着去毛边开孔13外周在一个方向上形成,并且可以在与接合钢10横截面垂直的方向上形成。在本发明的示例性实施方式中,凸缘11可以在与接合钢10横截面垂直的方向上形成,但是本发明并不必然限定于此,而是可以调整凸缘11的方向和角度。进一步地,去毛边开孔13可以形成为圆形开孔。
另外,当接合钢10通过插入成型而形成于纤维20之间时,可以将树脂30引入到纤维20中。特别是,为了方便,示出了根据本发明的示例性实施方式的两层纤维20作为例子,但是本发明并不必然限定于此,而是可以形成多个层彼此重叠。当将树脂30引入到去毛边开孔13内和凸缘11外部时,可以在纤维20之间形成剪切强度增强部分40。
剪切强度增强部分40可以改进纤维20与接合钢10之间的剪切强度。剪切强度增强部分40的至少一部分的厚度可以大于复合材料的厚度和凸缘11的高度。换言之,复合材料的厚度t可以基于剪切强度增强部分40的厚度而变化。剪切强度增强部分40的厚度可以基于去毛边开孔13的高度而变化。
如上述配置的复合材料可以由纤维增强塑料(FRP)形成。纤维增强塑料可指可以通过使用玻璃纤维作为增强材料并注入树脂而增强的复合材料。此外,纤维增强塑料可以是轻质的,并且可以具有优异的成形性。特别是,通过使用可以包括碳纤维、芳族聚酰胺纤维和增强纤维等的新材料作为增强材料,纤维增强塑料可以作为具有增加的强度和改进的弹性的轻质材料加以应用。进一步地,焊接端15可以沿着未插入成型于接合钢10与纤维20之间的外部尖端形成。焊接端15可以将车身构件1与复合材料接合,并且焊接端15的一侧尖端部可以弯曲。
图1示出,两个接合钢10可以通过插入成型形成,以将复合材料与车身构件1接合并形成两个焊接端15。换言之,第一焊接端15可以在接合钢10朝向车身构件1延伸的部分形成,并且第二焊接端15可以在接合钢10延伸并弯曲的部分形成。接合钢10的数量和焊接端15的数量可以取决于将要与复合材料接合的车身构件1的形状。特别是,接合钢10可以在外部尖端处沿着焊接端15通过焊接W与车身构件1接合,并且可以改进接合强度。
因此,根据本发明的示例性实施方式的具有插入成型接合钢10的复合材料可以改进接合钢10与复合材料之间的剪切强度。特别是,当形成有沿一个方向具有凸缘11的多个去毛边开孔13的接合钢10可以通过在纤维20之间插入成型而形成时,可以引入树脂30。而且,具有插入成型接合钢10的复合材料可以改进接合强度,即使接合钢10的厚度未因去毛边开孔13所形成的剪切强度增强部分40而增加。接合钢10可以在外部尖端处经由焊接端15通过焊接W与车身构件1接合,并且可以改进接合强度。
尽管本发明结合目前认为的示例性实施方式进行描述,但应当理解,本发明不限于公开的示例性实施方式,而是相反,本发明意于涵盖各种变化方式和等同布置,其均包括在所附权利要求的精神和范围之内。
