Preliminary Study on GF/Carbon/Epoxy Composite Permeability in Designing Close Compartment Processing

Material Characterization for Reliable Resin Transfer Molding Process Simulation

“…Thus, measurements of only three distinct scalar coefficients is required, which can be done according to existing procedures reported in the literature [13][14][15][16][17][18][19][20][21]. A further simplification is possible: as the thickness of the reinforcement is small compared to its length and width, the problem can be assumed to be 2D.…”

“…Most of them evaluate the in-plane permeability [13,14], concluding that radial flow (liquid injected from transverse direction at well-defined locations to evaluate 2D permeability) and linear flow (liquid injected from one end of the composite preform to evaluate 1D permeability) experiments give consistent results. The through-the-thickness permeability is more complex to determine [15][16][17][18][19][20][21] and is usually neglected because of the small thicknesses of the preforms.…”

Practicality of Ad Hoc Online Assessments for Teaching ESP in Online Flipped Classrooms during COVID-19

“…More experimental action research [15] is needed to further evaluate the practicality issues of online assessments for other courses and domains, which include (but are not limited to) aviation [16][17][18], engineering [19][20][21], health [22][23][24] and management [25]. The multitude of educational programs offered by various levels of learning institutions have been mostly affected by the pandemic.…”
