Abstract With the application of carbon fiber reinforced plastics (CFRPs), damage behaviors and mechanisms are desirable to understand. In this work, Bismaleimide (BMI) matrix composites were employed study mechanism under transverse loading through quasi-static indentation, where optical microscopy, ultrasonic C-scan, scanning electron microscope subjected examine damaged regions. The results ...
Probabilistic edge-delamination strength of a thermosetting polymer composite was studied experimentally in this work. During the procedure, by means of edge-delamination tensile test, the graphite–fiber/epoxy laminate made of unidirectional Toray P7051S-20Q-1000 prepregs with an optimized lay-up of [122/–122/02]S was used for examining its probabilistic distributions of the edge-delamination o...

Fluid shear stress alters the morphology and function of the endothelium by activating several kinases. Furthermore, shear stress potently inhibits apoptosis of endothelial cells. Since activation of Akt kinase has been shown to prevent cell death, we investigated the effects of shear stress on Akt phosphorylation. To test the hypothesis that shear stress interacts with the Akt kinase pathway, ...
Thermal effects on the pin-bearing behavior of an IM7/PETI5 composite laminate are studied comprehensively. A hypothesis presents factors influencing a change in pin-bearing strength with a change in temperature for a given joint design. The factors include the change in the state of residual cure stress, the material properties, and the fastener fit with a change in temperature. Experiments ar...
BACKGROUND Atherosclerotic lesions are predominantly observed in curved arteries and near side branches, where low or oscillatory shear stress patterns occur, suggesting a causal connection. However, the effect of shear stress on plaque vulnerability is unknown because the lack of an appropriate in vivo model precludes cause-effect studies. METHODS AND RESULTS We developed a perivascular shea...
The interlaminar shear characteristics of a polyurethane (PU) mixture composite structure, quantitatively calculating its energy consumption and carbon emissions were analyzed in this study. Inclined tests carried out on thirteen structures without treatment, high-temperature water bath accelerated loading conducted three structures; further, the strength tire trace position after test was test...
