An Investigation Of Mechanical Properties Of Composites Containing Recycled Rubber Particles, Ryan C. Archey

Masters Theses

In order to promote applications of recycled automobile tires, composite materials of recycled rubber tire particles with ethylene co-vinyl acetate (EVA), polybutadiene (PB), and Primacor were studied in the thesis. The composites were processed using a single screw extruder and a pelletizer. Compression molding was used to form specimens for hardness and impact tests. Mechanical properties of the composites were investigated in terms of tensile strength, percent elongation, Durometer hardness, and impact energy.

In this study, the content of recycled rubber was between 0 and 40 percent. Various matrices were processed using a combination of EVA, PB, or Primacor to …

Nonlinear Finite Element Micromechanic Analysis Of Thermoplastic Composite Of Recycled High Density Polyethylene Reinforced With Short Glass Fibers, Qiming Lou

Masters Theses

This thesis studied the nonlinear micromechanic behavior of thermoplastic composite of recycled high density polyethylene (HDPE) reinforced with short glass fibers using finite element method. The composite material was modeled using a micromechanic unit cell to simulate the stress distribution between the plastic matrix and the fiber in the composite. Nonlinear behavior of recycled HDPE and imperfect bonding between the fiber and matrix were investigated. Load-bearing capability of the fiber was evaluated using stress partition ratio (SPR) in the composite models. The effect of fiber aspect ratio on the stress distribution of the composite was studied to optimize the material …
