Mechanical characterization of cellulose nanofiber and bio-based epoxy composite

Cellulose nanofibers are one class of natural fibers that have resulted in structures with remarkable mechanical properties. In this study, the cellulose nanofibers are used as reinforcements in the forms of layered films in a bio-derived resin. Assessment of swelling behavior is performed together with an assessment of the tension and fracture behavior. Crack resistance behavior is compared to...

Characterization of Regenerated Cellulose for Bio-based Epoxy Fibrous Composites

Bio-Based Aromatic Epoxy Monomers for Thermoset Materials.

The synthesis of polymers from renewable resources is a burning issue that is actively investigated. Polyepoxide networks constitute a major class of thermosetting polymers and are extensively used as coatings, electronic materials, adhesives. Owing to their outstanding mechanical and electrical properties, chemical resistance, adhesion, and minimal shrinkage after curing, they are used in stru...

Epoxy Resins in Electron Microscopy

A method of embedding biological specimens in araldite 502 (Ciba) has been developed for materials available in the United States. Araldite-embedded tissues are suitable for electron microscopy, but the cutting qualities of the resin necessitates more than routine attention during microtomy. The rather high viscosity of araldite 502 also seems to be an unnecessary handicap. The less viscous epo...
