技术领域
本发明涉及一种用于车辆的保险杠横梁。
背景技术
通常而言，车辆保险杠横梁是置于车辆前部或后部的冲击吸收部件，其通过在低速车辆碰撞中的弹性变形来将对车辆的物理损坏降至最低，并通过在与另一车辆或固定物体的碰撞中吸收冲击来保护乘客并将车辆的变形降至最低。当保险杠横梁的强度增加时，重量和成本增加，相反地，当重量和成本降低时，强度降低，因此无法充分达成该功能。因此，已经开发出作为更轻和更强材料的玻璃纤维毡增强热塑性材料(下文称为“GMT”)。
GMT是一种高级材料，其是由作为常见树脂的聚丙烯树脂与玻璃纤维毡增强材料构成的片状复合材料。具体而言，将通过T模挤出的熔融聚丙烯与玻璃纤维无纺毡进行直接浸渍，从而向树脂提供改善的结合力。此外，玻璃本身的强度在毡型中被增强，且该强度高于其他材料。通常而言，GMT具有轻的重量且设计自由度是塑料的特征，并且热塑性树脂还提供高的生产率和可重用性。
前保险杠横梁针对高速碰撞进行保护，然而，当其由具有改善的抗冲击性的GMT制成时，保险杠横梁在高速碰撞中断裂，因此不能以其自身进行使用。然而最近，已经开发出通过在GMT中插入钢而制造的横梁；这在降低重量方面受到限制。此外，同时使不同的材料成型会增加加工难度。
在本部分公开的上述信息仅用于增强对本发明背景的理解，因此其可能包含不构成该国本领域普通技术人员已知的现有技术的信息。
发明内容

根据本发明示例性实施方式的用于车辆的保险杠横梁100可以包含玻璃纤维毡增强塑料复合材料10以及布置在玻璃纤维毡增强塑料复合材料10内的碳纤维增强塑料复合材料20。
图1示出汽车保险杠的示例性实施方式。该示例性实施方式涉及用于车辆的保险杠横梁100。用于车辆的保险杠横梁100可以划分成内部部分和外部部分。当从上方看车辆时，车辆的内侧与客舱相邻且面向客舱，且车辆的外侧背向客舱朝向周围环境。例如，对于前保险杠，车辆的前侧是外部且车辆的后侧是内部。
图2A示出根据示例性实施方式的保险杠横梁100的横截面图。如图2A所示，当碳纤维增强塑料复合材料20被布置在玻璃纤维毡增强塑料复合材料10内时，根据示例性实施方式的保险杠横梁100可以具有基本上U型的横截面。在外部的具有玻璃纤维毡增强塑料复合材料10的结构保护在内部的碳纤维增强塑料复合材料20。此外，具有高抗拉强度的碳纤维增强塑料复合材料20可以增强保险杠横梁100的施加有最大张力的部分，由此改善机械特性。
不像保险杠横梁100的示例性横截面结构，当选择图2B或图2C所示的结构时，机械特性可能变得有问题。具体而言，如图2B所示，当碳纤维增强塑料复合材料20被布置在玻璃纤维毡增强塑料复合材料10之间时，当应力在理论上为0时，碳纤维增强塑料复合材料20会位于保险杠横梁100的在碰撞时弯曲的部分，从而效能会降低。此外，如图2C所示，当碳纤维增强塑料复合材料20被布置在外部时，在碰撞过程中冲击负荷会施加至碳纤维增强塑料复合材料20，效能会降低。
在高速碰撞中，在根据示例性实施方式的保险杠横梁100的横截面结构中，玻璃纤维毡增强塑料复合材料10可以主要抵抗大量前部的冲击负荷，且具有高性能的碳纤维增强塑料复合材料20可以抵抗大量后部的冲击负荷。玻璃纤维毡增强塑料复合材料10可以包含约45～60wt％的聚丙烯、约35～45wt％的玻璃纤维、约0.1～10wt％的交联剂、约0.1～4wt％的过氧化物、以及约0.1～4wt％的抗氧化剂。
当玻璃纤维增强材料与聚丙烯结合时，玻璃纤维毡增强塑料复合材料10有助于改善特性。在本发明中，聚丙烯与玻璃纤维的结合力可以通过加入交联剂而增加。交联剂可以不限于特定物质，但是可以采用马来酸酐。例如，可以加入过氧化物来控制聚丙烯的熔融指数MI，且可以加入抗氧化剂来防止聚丙烯的氧化。抗氧化剂可以不限于特定物质，但是可以采用IRGANOX。
此外，玻璃纤维可以包含单向玻璃纤维和随机方向玻璃纤维，因此不仅可以在轴向上，而且还可以在横向上改善特性。具体而言，整体玻璃纤维可以包含约40～60wt％的单向玻璃纤维和约40～60wt％的随机方向玻璃纤维。采用经胶粘剂处理的玻璃纤维可以进一步增加聚丙烯与玻璃纤维之间的结合力。氨基硅烷可以被用作胶粘剂。
碳纤维增强塑料复合材料20可以包含约40～60wt％的热塑性树脂和约40～60wt％的在预定方向上排布的碳增强纤维。具体而言，碳纤维增强塑料复合材料20还可以包括添加作为热塑性树脂的聚丙烯。可以以约40～60wt％的量包含碳增强纤维。当包含不足量的碳增强纤维时，可能无法达到充分的抗拉强度。此外，当包含过量的碳增强纤维时，与聚丙烯的结合力可能会降低。因此，碳增强纤维的含量可以在上述范围内调整。
当将碳纤维增强塑料复合材料20布置在玻璃纤维毡增强塑料复合材料内时，碳纤维增强塑料复合材料20可以具有约1.0～1.4GPa的抗拉强度和约65～80GPa的拉伸模量。结果是，与玻璃纤维毡增强塑料复合材料相结合的用于车辆的保险杠横梁的特性可以得以增强。
具体而言，根据示例性实施方式的用于车辆的保险杠横梁可以抵抗大量的冲击负荷，由此为汽车前保险杠横梁100提供支持。碳纤维增强塑料复合材料20可以包含由在轴向上排布的碳增强纤维构成的层以及由在横向上排布的碳增强纤维构成的层。例如，通过包含由在轴向上排布的碳增强纤维构成的层22和由在横向上排布的碳增强纤维构成的层21，可以改善轴向和横向上的弹性模量和抗拉强度。
如图3所示，在用于车辆的保险杠横梁100中，在碰撞中在轴向和横向上可能产生张力。例如，当碳纤维增强塑料复合材料20包含由在轴向上排布的碳增强纤维构成的层22，而不含由在横向上排布的碳增强纤维构成的层21时，无论在轴向上的弹性模量和抗拉强度是否较高，在横向上的弹性模量和抗拉强度会较低，因而保险杠在碰撞中可能会损坏。然而，当碳纤维增强塑料复合材料20同时包含由在轴向上排布的碳增强纤维构成的层22以及由在横向上排布的碳增强纤维构成的层21时，在轴向和横向上的弹性模量和抗拉强度均可以得以改善，由此降低保险杠在碰撞中破裂的可能性。
在碳增强纤维中，碳纤维增强塑料复合材料20可以包含约40～60wt％的在轴向上排布的碳增强纤维和约40～60wt％的在横向上排布的碳增强纤维。在上述范围内，在轴向和横向上的弹性模量和抗拉强度可以得以改善。此外，碳纤维增强塑料复合材料20可以具有的结构为，由在轴向上排布的碳增强纤维构成的层22和由在横向上排布的碳增强纤维构成的层21交替堆叠成两个或更多个层。在这样的结构中，在轴向和横向上的弹性模量和抗拉强度可以得以改善。
以下实施例更详细地阐述本发明。然而，以下示例性实施方式仅是本发明的实施例，且本发明不限于此。
示例性实施方式1
通过将包含56wt％的均聚级聚丙烯、2wt％的马来酸酐、1wt％的过氧苯甲酰和2wt％作为抗氧化物的IRGANOX的基质浸渍到玻璃纤维毡中，来制备厚度为4.7mm的玻璃纤维毡增强塑料复合材料(下文中称为“GMT”)。通过将50wt％的聚丙烯浸渍到碳增强纤维(ToreyT700)中，来制备厚度为0.25mm的碳纤维增强塑料复合材料(下文称为“CFRP”)。在全部碳增强纤维中，采用50wt％在轴向上排布的碳增强纤维和50wt％在横向上排布的碳增强纤维。CFRP片的示意性结构示于图4A中。前保险杠横梁通过将GMT片堆叠在所制备的CFRP片上、使其预热、将其与CFRP放在模具中并然后对其进行压制，经由模压成型而形成。

在与示例性实施方式1相同的条件下实施示例性实施方式5，除碳增强纤维有90wt％在轴向上排布且10wt％在横向上排布外。CFRP片的示意性结构示于图4B中。测定所制备的前保险杠横梁的轴向和横向上的弹性模量和抗拉强度，并示于以下表1中。此外，在碰撞测试车法中测定前保险杠横梁的性能，并确定存在开裂以及由后部断裂引起的碳纤维散落。
示例性实施方式6
在与示例性实施方式1相同的条件下实施示例性实施方式6，除使用在轴向上排布的碳增强纤维外。测定所制备的前保险杠横梁的轴向和横向上的弹性模量和抗拉强度，并示于以下表1中。
表1
如表1所示，与其他示例性实施方式相比较，在示例性实施方式1和示例性实施方式2中，在轴向上排布的碳增强纤维与在横向上排布的碳增强纤维的重量比被适当控制，从而轴向和横向上的弹性模量和抗拉强度可以得以提高，因此其适用于车辆用前保险杠横梁。
尽管本发明已经结合当前被认为是示例性实施方式的内容进行了描述，应当理解的是，本发明不限于所公开的示例性实施方式，相反，本发明意在涵盖在所附权利要求的主旨和范围内包含的多种修改和等同配置。因此，上述的示例性实施方式仅是实施例，且不应被解读为在任何方面受到限制。
