Sisal fiber-reinforced composites have huge potential applications in many industries. Different defects during the production process of composite may decrease performance these composites. In present work, one important such as waviness sisal fiber has been studied under compressive loading. Two types materials are considered for study. One is polymer matrix and another hybrid i.e carbon nano...

Wet Fiber Placement (WFP) is a novel process for manufacturing complex shaped parts from continuous fiber-reinforced polymers without semi-finished products. Here, dry fiber bundles (rovings) are in-line impregnated with thermoset resin, followed by almost tension-free deposition. The freshly and limp rovings allow placement in radii. Due to the lack of compression deposition, subsequent consol...

Abstract Part II describes the experimental assessment and application of ideas in I concerning mechanisms that determine role blade surface waviness on laminar-turbulent transition their consequent effect civil aircraft fan performance. A natural wind tunnel was designed constructed to characterize impact transition, using both hotwire anemometry infrared thermography. The results support new ...
