The Woodruff School

SUMMARY

This study focuses on the addition of surface treated kaolin fillers to nylon based composites. The composites are produced using a twin-screw compounder and injection molding techniques and this study aim to identify:
1. The synergies between glass fibers and kaolin in a Nylon 6 matrix.
2. The effects on the mechanical properties of the composite due to changing the matrix from Nylon 6 to Nylon 66.

Glass fibers are inherently abrasive in nature and can cause excessive damage to machines used in their production. By adding kaolins to composites, this study analyzes the potential of reducing or eliminating the use of glass fibers in polymer composites. Not only will this help to reduce production costs but will also help yield a better surface finish for components.
