Atmospheric chemistry and aerosol associated with the coastal urban environment
… two OA factors - less-oxidized oxygenated OA (LO-OOA), and more-oxidized oxygenated OA (MO-OOA) - represent SOA, a mass balance model was used to estimate the SOA formation rate. For MO-OOA, the largest formation rates aligned with intense photo-oxidation processes. For LO-OOA, the most …

Nanomaterial-enabled manufacturing for next-generation multifunctional advanced composite prepreg laminate architectures
… of alternatives, for example, out-of-autoclave (OoA) specially-formulated prepregs that only require heat and vacuum (i.e., pressure is not required). OoA prepreg processing also has drawbacks due to their specialized morphological and chemical formulation for vacuum-only conditions, as well as …

A Comparison of Crushing Parameters of Graphite Composite Thin-Walled Cylinders Cured in Low and High Pressures
<p>Out-of-Autoclave (OoA) processes for manufacturing aerospace-grade parts needs to be better understood to further the development and success of industries that are manufacturing reusable launch vehicles, military and commercial aircraft, and spacecraft. Overcoming the performance limitations …

Advanced composites using non-autoclave processes: manufacturing and characterization
… vacuum-bag-only cure out-of-autoclave (OOA) manufacturing process was studied. Physical and mechanical performance of the composites was evaluated. The influence of size, lay-up configuration, thickness and their interactions on the impact behavior of the composites was studied using …

Micro-computed tomography for interlaminar analysis, void quantification, and feature localization in carbon fiber composites
… autoclave-cured AS4/8552 and out-of-autoclave (OoA) IM7/M56. Laminates of each material were manufactured with and without vertically aligned carbon nanotubes (CNTs) reinforcing the interlaminar region; this hierarchical nanoengineered architecture, termed nanostitching, is of interest in other …

Out of autoclave manufacturing of cfrps having multiscale reinforcement for improved interlaminar fracture toughness and multifunctional characteristics
… introduction of CNTs during Out-of-Autoclave (OoA) processes such as liquid resin infusion (LRI) or resin transfer molding (RTM). The present Dissertation aims to the development of Out-of-Autoclave Carbon Fibre Reinforced Polymers (CFRPs) with improved interlaminar fracture toughness and …

CPU/GPU Code Acceleration on Heterogeneous Systems and Code Verification for CFD Applications
Computational Fluid Dynamics (CFD) applications usually involve intensive computations, which can be accelerated through using open accelerators, especially GPUs due to their common use in the scientific computing community. In addition to code acceleration, it is important to ensure that the code …
