A series of studies were conducted to investigate the effect of LCP inclusion on the processability of short glass fiber reinforced toughened nylon 6,6. The objective was to identify the role of each component phase and obtain composite synergism arising from a multi-component system. It was found that a hybrid composite offered superior processability over the glass fiber reinforced polymers a...

The objectives of this study were to determine and compare the chemical composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of ten pasture forage species dominant in the west provinces of Iran. Duplicate nylon bags of pasture samples were suspended in the rumen of four wethers for up to 96 h. The chemical com...

Inter-organizational design processes are inefficiently supported by management tools w.r.t. to their dynamic nature and inherent complexity. In this paper, we present an innovative framework for the definition, analysis, improvement, and management of such design processes. Key features are to bridge the gap between modeling and execution of inter-organizational design processes and the seamle...

The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile - digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The method outlined provides a simple experimental setup that can be used to evaluate the ultimate tensile st...
