Design with Ultra Strong Polyethylene Fibers

A study on impact and tensile strength of acrylic resin filled with short ultra-high molecular weight polyethylene fibers.

In dentistry, acrylates have been used for preparing denture bases for 50 years. Although polymethylmethacrylates (PMMA) are known to be an ideal base material, they possess some undesirable mechanical properties, especially their impact strength and tensile strength, which appear to be unsatisfactory for some applications. Additives and fibers have therefore been used to enhance and improve th...

High-density Polyethylene-based Composites with Pressure-treated Wood Fibers

High-Density Polyethylene (HDPE)-based composites with alkaline copper quaternary (ACQ)and micronized copper quaternary (MCQ)treated wood fibers were manufactured through injection molding. The mechanical properties, water absorption, and biological resistance properties of the fabricated composites with different coupling treatments were investigated. Composites with ACQand MCQ-treated wood ha...

Wear of Ultra High Molecular Weight Polyethylene

Ultra-low-loss tapered optical fibers with minimal lengths.

We design and fabricate ultra-low-loss tapered optical fibers (TOFs) with minimal lengths. We first optimize variations of the torch scan length using the flame-brush method for fabricating TOFs with taper angles that satisfy the adiabaticity criteria. We accordingly fabricate TOFs with optimal shapes and compare their transmission to TOFs with a constant taper angle and TOFs with an exponentia...

Strong, light, multifunctional fibers of carbon nanotubes with ultrahigh conductivity.

Broader applications of carbon nanotubes to real-world problems have largely gone unfulfilled because of difficult material synthesis and laborious processing. We report high-performance multifunctional carbon nanotube (CNT) fibers that combine the specific strength, stiffness, and thermal conductivity of carbon fibers with the specific electrical conductivity of metals. These fibers consist of...
