Fiber Reinforced Concrete01:22

Fiber Reinforced Concrete

67
Fiber-reinforced concrete significantly enhances the structural and nonstructural properties of traditional concrete by incorporating fibers like steel, glass, and polymers. These fibers, varying from natural ones such as sisal and cellulose to manufactured ones like polypropylene and Kevlar, are mixed into hydraulic cement with aggregates. Steel fibers, often preferred for their robustness, contribute to improved ductility, toughness, and post-cracking performance. The concrete is classified...

Thermal Insulation in Masonry Walls

103
In hot, dry climates, the thermal mass of masonry walls can be beneficial, absorbing heat during the day and releasing it at night, thereby stabilizing indoor temperatures. However, in most other climates, additional insulation is necessary to enhance thermal resistance.
External insulation can be applied using an Exterior Insulation and Finish System (EIFS), which involves affixing panels of plastic foam to the wall and covering them with a polymeric stucco reinforced with glass fiber mesh....

Area of Science:

  • Materials Science
  • Polymer Science
  • Thermal Engineering

Background:

  • Reflective thermal insulation is key for energy efficiency, preventing heat gain by reflecting solar radiation.
  • Previous work created porous polypropylene (PP) with high solar reflectivity, but lacked mechanical strength for practical applications.
  • Mechanical limitations of neat porous PP hinder its use in thermal insulation due to installation and environmental stresses.

Purpose of the Study:

  • To enhance the mechanical properties and reflective thermal insulation performance of porous polypropylene.
  • To explore the application of solvent-based surface modification technology on glass fiber (GF)-reinforced PP composite sheets.
  • To investigate the combined effects of GF reinforcement, nucleating agents, and surface modification on material properties and thermal performance.

Main Methods:

  • Solvent-based surface modification applied to glass fiber (GF)-reinforced polypropylene composite sheets.
  • Incorporation of 30 wt% GF, nucleating agents, and surface modification.
  • Characterization of micro- and nano-structured porous outer layers and spherulite sizes (0.5-2.0 μm).

Main Results:

  • Achieved enhanced modulus (~4 GPa) and tensile strength (60 MPa) in the composite sheets.
  • Reached an average solar reflectance of up to 94%.
  • Demonstrated a significant reduction in inner temperature by 24.1 °C compared to neat PP sheets.

Conclusions:

  • The solvent-based surface modification effectively improved mechanical properties and reflective thermal insulation of PP composites.
  • The combination of GF reinforcement, nucleating agents, and surface modification is crucial for high performance.
  • This technology offers a pathway to cost-effective, efficient porous PP composite sheets for reflective thermal insulation applications.
