  • bolt bearing strength of commingled Boron glass Fiber reinforced aluminum laminates
    ASME 2012 International Mechanical Engineering Congress and Exposition, 2012
    Co-Authors: Poching Yeh, Poyu Chang, J M Yang, Ming C Liu
    Abstract:

    The bearing properties of recently developed hybrid Fiber/metal laminates, or COmmingled Boron/glass Fiber Reinforced Aluminum laminates (COBRA), are investigated in this study. The bolt-type bearing tests on GLass REinforced aluminum laminates (GLARE), non-commingled hybrid Boron/glass/aluminum Fiber/metal laminates (HFML) and COBRA were carried out as a function of e/D ratio, metal volume fraction, Fiber volume fraction, and Fiber orientation.Experimental results show that with the same joint geometry and metal volume fraction, the commingling of Boron Fibers improves the bearing strength of Fiber/metal laminates. The bearing strength of COBRA with longitudinal Fibers is lower than that with transverse Fibers due to the fact that shearout failure takes place before maximum bearing strength is reached. The experimental results show that, with only either transverse Fiber orientation or longitudinal Fiber orientation, COBRA with 18% Boron Fiber volume fraction possesses a higher bearing strength when compared to HFML with 6% Boron Fiber volume fraction. In addition to the properties in COBRA with parallel-plies commingled prepreg, the bearing properties of various COBRA with [0°/90°] and [0°/90°/90°/0°] cross-ply commingled prepregs are also discussed.© 2012 ASME

    Abstract The bearing properties of recently developed hybrid Fiber/metal laminates, or COmmingled Boron/glass Fiber Reinforced Aluminum laminates (COBRA), are investigated in this study. The bolt-type bearing tests on GLass REinforced aluminum laminates (GLARE), non-commingled hybrid Boron/glass/aluminum Fiber/metal laminates (HFML) and COBRA were carried out as a function of e / D ratio, metal volume fraction, Fiber volume fraction, and Fiber orientation. Experimental results show that with the same joint geometry and metal volume fraction, the commingling of Boron Fibers improves the bearing strength of Fiber/metal laminates. Observations show the Boron/glass Fiber prepreg, transverse to the loading direction, results in a bearing mechanism that effectively increases the bearing strength. The bearing strength of COBRA with longitudinal Fibers is lower than that with transverse Fibers due to the fact that shearout failure takes place before maximum bearing strength is reached. The experimental results show that, with only either transverse Fiber orientation or longitudinal Fiber orientation, COBRA with 18% Boron Fiber volume fraction possesses a higher bearing strength when compared to HFML with 6% Boron Fiber volume fraction.

  • fatigue crack initiation in hybrid Boron glass aluminum Fiber metal laminates
    Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 2008
    Co-Authors: Poyu Chang, Poching Yeh, Jennming Yang
    Abstract:

    Abstract The fatigue crack initiation behavior of a high modulus and hybrid Boron/glass/aluminum Fiber/metal laminate (FML) was investigated experimentally and analytically. Two types of hybrid Boron/glass/aluminum FMLs were fabricated and studied, which consisted of aluminum alloy sheets as the metal layers and a mixture of Boron Fibers and glass Fibers as the composite layers. For the first type, the Boron Fiber/prepreg and the glass Fiber/prepreg were used separately in the composite layers, and for the second type, the Boron Fibers and the glass Fibers were mingled together to form a hybrid Boron/glass/prepreg composite layer. These hybrid FMLs were consolidated using an autoclave curing process. The incorporation of the Boron Fibers improved the Young's modulus of the composite layer in FMLs, which in turn, would improve the fatigue crack initiation life of the Al sheet. The experimental results clearly showed that the fatigue crack initiation lives for both types of hybrid Boron/glass/aluminum FMLs were superior to the monolithic aluminum alloy under the same loading condition. An analytical approach was proposed to calculate the fatigue crack initiation lives of hybrid Boron/glass/aluminum FMLs based on the classical laminate theory and the small-crack theory. A good correlation was obtained between the predictions and the experimental results.
