Mechanical and Microscopic Characteristics of Polyurethane-Based Pervious Pavement Composites

چکیده
Conventional pervious pavement materials (PPM) that consist of cement and aggregate are known for poor durability due to their brittle behavior. Thus, enhance the durability, we fabricated polymeric PPMs from durable abundant polyurethane (PU) undertook mechanical microscopic characterizations. PU-based PPM samples with varying sizes were produced examined test compressive strength water permeability. Furthermore, X-ray micro-computed tomography (micro-CT) was implemented analyze samples’ pore tortuosity characteristics. Through micro-CT analysis, morphological characteristics PPM’s internal structures identified quantitively analyzed correlations between size distribution, connectivity, within samples. Finally, microstructures derived generated as a finite element model also numerically determined stress distribution inside.

Mechanical Properties of Nonwoven Reinforced Thermoplastic Polyurethane Composites
Reinforcement of flexible fibre reinforced plastic (FRP) composites with standard textile fibres is a potential low cost solution to less critical loading applications. The mechanical behaviour of FRPs based on mechanically bonded nonwoven preforms composed of either low or high modulus fibres in a thermoplastic polyurethane (TPU) matrix were compared following compression moulding. Nonwoven pr...
