Correct modeling of flow and solidification of metal melt in the pressure infiltration process (PIP) is important for accurate simulation and process optimization of the mold-filling process during the making of metal matrix composites. The fiber reinforcements used in this process often consist of fiber tows or bundles that are …
The process of making the composite includes some main steps, during which waste plastic bags are first melted at 200°C-250°C and then mixed with sand aggregates. These coated aggregates are then mixed with cement and water into mortar. Moulded specimens of derived composites are then submitted to hydrothermal ripening …
High-strength engineered cementitious composites (HS-ECC) has gained significant attention due to its superior mechanical properties. Despite its advantageous properties, HS-ECC faces challenges such as high shrinkage and resource shortage due to a lack of coarse aggregate and excessive consumption of silica sand, resulting in challenges for …
