蜂窝夹层结构的梁与I型梁相似:其表层承受弯曲应力,相当于I型梁的翼板,其中心部承受剪切应力,相当于I型梁的腹板,同时使表层保持稳定以抵抗纵向弯曲(I型梁由翼板抵抗纵向弯曲)。对I型梁的宽度限制不适用于蜂窝夹层梁。将蜂窝材料用于制造飞机的主要构件,这在50年代中期就已经是确有把握的了。到60年代中期,出现了更成熟的环氧树脂粘结法,此后随着材料的发展,导致酚醛加强的蜂窝芯材与纤维加强的塑料面材相结合的夹 Beams of honeycomb sandwich structure are similar to I-beams: the surface is subjected to bending stress, which corresponds to the flange of the I-beam, the center of which is subjected to shear stress, which corresponds to the web of the I-beam while keeping the surface stable against Bending longitudinally (I-beams are resistant to longitudinal bending by wings). The width limit for I-beams does not apply to honeycomb sandwich beams. The use of honeycomb materials in the manufacture of the main components of the aircraft was already certain in the mid-1950s. By the mid-1960s, more sophisticated epoxy bonding methods emerged, and as the material evolved thereafter, the phenolic-reinforced honeycomb core material combined with the fiber-reinforced plastic facestock
