A protocol to expose bare fibers on the composite surface by eliminating resin rich area is presented. The fibers are exposed during fabrication of the composites, not by the post surface treatment. The exposed carbon composites exhibit high electrical conductivity in the through-thickness direction and high mechanical property.

Dipole Moment of a Molecule Polar covalent bonds connect two atoms with differing electronegativities, leaving one atom with a partial positive charge (δ+) and the other atom with a partial negative charge (δ–), as the electrons are pulled toward the more electronegative atom. This separation of charge gives rise to a bond dipole moment. The magnitude of a bond dipole moment is represented by the Greek letter mu (µ) and is given by the formula shown here, where Q is the magnitude of the...

Classifying Matter by Composition

Matter: Pure Substances and Mixtures According to its composition, the matter can be classified into two broad categories — pure substances and mixtures. A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated. A mixture is composed of two or more types of...

VSEPR Theory and the Basic Shapes

2020
Overview of VSEPR Theory Valence shell electron-pair repulsion theory (VSEPR theory) enables us to predict the molecular structure, including approximate bond angles around a central atom, of a molecule from an examination of the number of bonds and lone electron pairs in its Lewis structure. The VSEPR model assumes that electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between these electron pairs by maximizing the distance between them.
FAQs
Centroid calculation depends on both the size of each component and its geometric location. Engineers first determine the area of every rectangle, triangle, circle, or semicircle, then combine those component values with their positions to locate the overall centroid. This shows how the placement of material shifts the section’s representative geometric center.
The moment of inertia helps engineers evaluate how a composite shape behaves when resisting bending. Its value depends on the arrangement and geometric properties of the component shapes, so the calculation must account for the complete configuration rather than one isolated part. This information supports predictions about the mechanical performance of beams and other components.
Combining components allows an irregular profile to be analyzed through simpler, recognizable shapes. Each rectangle, triangle, circle, or semicircle contributes its own area and location, while the assembled values describe the complete section. This approach makes complicated engineering geometries more manageable without ignoring how their parts are arranged.
Composite shapes become especially useful when a structural section, machine component, or manufactured part has an irregular profile that cannot be represented conveniently by one basic figure. Breaking the profile into simpler parts lets engineers determine overall dimensions, centroids, and moments of inertia needed to assess material placement and mechanical behavior.
Begin by dividing the overall profile into suitable basic geometric components. Calculate the area of each component and identify its geometric location. Then combine those values to determine the required overall property, such as the centroid or moment of inertia. The resulting calculation describes the complete configuration rather than treating its parts independently.
Engineers apply these calculations to beams, structural sections, machine components, and manufactured parts with nonuniform or irregular profiles. The results help estimate material requirements, describe how material is distributed, and evaluate how the component may respond to bending or other mechanical forces during design and analysis.
Depending on the quantities combined, the analysis can provide overall dimensions, the centroid, and the moment of inertia of the complete profile. These results give engineers a clearer basis for evaluating load distribution and resistance to bending, while also supporting decisions about the amount and arrangement of material in a designed part.
