Improving Compressive Strength Of High Modulus Carbon-Fiber Reinforced Polymeric Composite With Varying Modulus Fibers, Sarvenaz Ghaffari

Mechanical and Aerospace Engineering Dissertations - Archive

There has been a strong demand in using high-modulus (HM) carbon-fiber composites potentially enabling lightweight aircraft structures with significant weight savings. However, extremely low fiber-direction compressive strength has been a well-recognized weakness of the HM composites, preventing their implementation in aircraft platforms. Fiber-direction compressive strength of HM and intermediate-modulus (IM) carbon fiber-reinforced polymers (CFRP’s) is presumably governed by microstructural stability. However, strong decrease in fiber-direction compressive strength of HM carbon-fiber composites, compared to their intermediate modulus (IM) counterparts, contradicts predictions from available microstructural buckling theories. A recent work demonstrated that significant improvement in the fiber-direction compressive strength of HM carbon-fiber …

Earth & Environmental Sciences Theses - Archive

The prolific levels of oil and gas production from the shale revolution have been plagued by steep initial production decline and inefficiencies in recovering the total hydrocarbons in place. Even the widespread practice of using multi-well sites with closely spaced wellbores has failed to yield a moderate fraction of the potential resources. It is hypothesized that the constraints of shale production arise from its nano-pore structure. Slow, diffuse hydrocarbon transport from the shale matrix to the stimulated fracture network is a likely production bottleneck. Understanding transport phenomena from this tight, porous matrix to the fracture via nanometer-scale pathways is essential …
