    • A core structure (50), apparatus (170), and method which utilize laser bonding to fabricate the core structure. The core structure (50) is characterized by laser bonds (14) in patterns between adjacent sheets (20, 22, 24, 26, 28) of aluminum, stainless steel, and titanium foil which create honeycomb core structures (50) when the bonded stack of sheets is expanded by the application of tensional forces thereto. A variable density core structure (50) incorporates honeycomb cells (34) of conventional size and a higher density honeycomb core structure (60) is formed integrally with the original core structure (40). The higher density core (60) has cells (62) which are much smaller than the cells (34) of the original core structure (40). The apparatus (70) achieves the fabrication of the core structure and the steps of the method are practised by either hand or utilization of the apparatus.
    • 一种芯结构(50),装置(170)和利用激光焊接来制造核心结构的方法。 芯结构(50)的特征在于,当相互接合的铝,不锈钢和钛箔的相邻片材(20,22,24,26,28)之间的图案中,激光键合(14)形成蜂窝状核心结构(50) 通过向其施加张力而使一叠片材膨胀。 可变密度芯结构(50)包括常规尺寸的蜂窝单元(34),并且与原始芯结构(40)一体形成更高密度的蜂窝芯结构(60)。 较高密度的核心(60)具有小于原始核心结构(40)的单元(34)的单元(62)。 设备(70)实现了芯结构的制造,并且该方法的步骤通过手或利用该装置来实现。
