Injection Molding of Plastics from Agricultural Materials

OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...

Formal Methods Tool Qualification

Qualification of Formal Methods Tools

Formal methods tools have been shown to be effective at finding defects in and verifying the correctness of safety-critical systems, many of which require some form of certification. However, there are still many issues that must be addressed before formal verification tools can be used as part of the certification of safety-critical systems. For example, most developers of avionics systems are...

Quality Control of Raw Materials

Food influences the health of a population to a great degree, therefore, the control of food quality is an important government activity, and is legislatively regulated. Raw food materials quality is a complex term that includes nutritional, sensory, hygienictoxicological, and technological points of view. Food has to fulfill all quality requirements, but above all, it has to be safe. High qual...

Normal and Parallel Permeability of Preform Composite Materials used in Liquid Molding Processes: Analytical Solution

The permeability of the preform composite materials used in liquid molding processes such as resin transfer molding and structural reaction injection molding is a complex function of weave pattern and packing characteristics. The development of tools for predicting permeability as a function of these parameters is of great industrial importance. Such capability would speed process design and op...
