The development of sub-micro filler enhanced polymer composites
… efficiency in mechanical reinforcement at high filler loadings. The surface area of nano-fillers in high filler loaded composites is too high resulting in insufficient polymer molecules to wet the filler surface and hence increased filler agglomeration occurs. Increasing filler dimension into …

Rheology And Organic Filler Interactions in Phenolic Resin Formulations
… residue. These organic waste products act as fillers that reduce the cost, increase the viscosity, and affect the rheology of the fillers. Wheat flour is added as an extender to reduce cost and affect the tack of the adhesive. These organic fillers are lignocellulosic materials that are made …

Analysis of grounding performance for different bio filler medium effect
… significantly. As a conclusion, pineapple leaves filler shows better medium for enhancing the grounding system performance compared with coir filler due to lower lower grounding resistance. Copper sulfate was able to reduce the ground rod resistance value temporarily although for a short duration.

Polymer Crystallization: Micro- and Nano- Filler Effects on Isotactic Polypropylene
… morphology, studies about the effects of fillers on the crystallization behavior of composites are of great interest. Nucleated crystallization has been the subject of several studies over the last 50 years or so [Cormia et al. 1962, Binsbergen 1970, Mercier 1990]. In the relative simple …

Investigation of Weldability in High-Cr Ni-base Filler Metals
High-Cr Ni-base alloys have been used in the nuclear industry for weld overlay repair of dissimilar metal welds which have been affected by primary water stress corrosion cracking. During welding, defects may result from super-solidus and sub-solidus cracking phenomena. The ability to evaluate and …

Toughening mechanisms in composites of miscible polymer blends with rigid filler particles
Fillers are often added to polymers improve stiffness at the cost of reduced toughness, but this tradeoff is not universal. Well-dispersed microscopic particles have been shown to improve toughness and stiffness simultaneously in some cases. The effect depends on interparticle distance as well as …
