Polymer Liquid Crystal (PLC) and Polypropylene Interlayers in Polypropylene and Glass Fiber Composites: Mechanical Properties

Polymer Liquid Crystal (PLC) and Polypropylene Interlayers in Polypropylene and Glass Fiber Composites: Mechanical Properties

Description: In recent developments of composite materials, scientists and engineers have come up with fibers as well as matrices for composites and techniques of blending high cost components with low cost materials. Thus, one creates cost effective composite materials that are as efficient as space age components. One of the major breakthroughs in this area is the innovation of molecular composites, specifically polymeric liquid crystals (PLCs). These materials have excellent mechanical properties such as tensile impact and bending strength. They have excellent chemical resistance, low thermal expansivity, and low flammability. Their low viscosity leads to good processability One major setback in using space age composite technology in commercial applications is the price. Due to the complexity of processing, the cost of space composite materials is skyrocketing. To take the same concept of space age composite materials to create a more economical substitute has become a serious concern among scientists and engineers around the world. The two issues that will be resolved in this thesis are: (1) the potential impact of using PLCs (molecular reinforcement) can have on macro reinforced (heterogeneous composite, HC) long fiber systems; and (2) how strategic placement of the reinforcing layers can affect the macromechanical properties of the ...
