This work aims to facilitate the development of standardized techniques for impregnating or grafting aminated compounds onto silica substrates, which are often broadly described in the literature. Specific amounts of solvent, substrate, amines, and the values of other important experimental parameters will be discussed in detail.

In this work, we prepared an adsorbent composed of the cationic N,N-dimethylamino propylacrylamide methyl chloride quaternary (DMAPAAQ) polymer gel and iron hydroxide for adsorbing arsenic from groundwater. The gel was prepared via a novel method designed to ensure the maximum content of iron particles in its structure.

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.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Fiber-reinforced polymeric materials (FRP) are composite materials that are formed by longitudinal fibers embedded in a polymeric resin, thereby creating a polymer matrix with aligned fibers along one or more directions. In its simplest form, the fibers in FRP materials are aligned in an orderly, parallel fashion, thus imparting orthotropic material characteristics, meaning that the material...

Quasistatic Mechanical Testing for Computer-Aided Design and Manufacturing Occlusal Veneers Cemented to Milled Dentin Analog Material

2024
A quasistatic load-to-fracture test with a non-fixed stainless steel ball was developed to determine the fracture strength of minimally invasive posterior computer-aided design and manufacturing restorations cemented to dentin analog materials. This test models the typical loading regime responsible for the fracture of dental restorations.
FAQs
Vacuum, pressure, or their combination drives liquid resin into internal pores, cracks, and voids rather than leaving defects untreated at the surface. This choice is important because the treatment must reach discontinuities throughout the material. Effective penetration restores continuity within the part, supporting improved integrity and reducing pathways that could permit leakage or corrosion.
Curing transforms the penetrated liquid resin through a chemical reaction into a rigid, bonded polymer. This conversion locks the resin inside the treated structure and helps stabilize previously weak or discontinuous regions. The resulting bond contributes to structural continuity, allowing the process to address internal damage rather than merely covering it with a surface layer.
Filling pores, cracks, and voids removes open discontinuities that can weaken a part or connect its interior with the surrounding environment. After curing, the resin helps restore continuity and seal the structure. These changes can reduce leakage and corrosion pathways while improving the component’s integrity, making defect treatment relevant to manufactured engineering products.
A typical treatment places a porous or damaged component in contact with liquid epoxy resin, then uses vacuum, pressure, or both to promote penetration into its defects. The resin remains within the internal spaces while a chemical curing reaction converts it into a rigid polymer. The treated part can then be evaluated for restored continuity and integrity.
The process is applicable to castings, electrical components, composites, and other manufactured parts that contain pores, cracks, or voids. Its value depends on the engineering need: it can stabilize castings, support insulation in electrical components, reinforce composite structures, or extend the service life of products requiring sealed and continuous internal structure.
In quality control, impregnation helps address defects that may compromise a manufactured part, while also revealing the presence of discontinuities that require attention. In repair, the cured resin restores continuity and seals damaged regions. These outcomes support inspection, insulation, leakage reduction, corrosion-pathway control, and service-life extension across several engineering applications.
