Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, EarlyView.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Optimal design for epoxy polymer concrete based on mechanical properties and durability aspects

, 2020
Polymer concrete has shown a number of promising applications in building and construction, but its mix design process remains arbitrary due to lack of understanding of how constituent materials influence performance.

Studies on Repairing of Concrete Cracks with Epoxy Resin

Journal of the Society of Materials Science, Japan, 1967
Cracks appearing on concrete or mortar of structures would reduce the life of structure and destroy its functions, because they cause permeation or penetration of air and moisture. For example, water permeation and air penetration through such cracks promote a corrosion of steel frames and bars.As a procedure to avoid such unfavorable consequences ...

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Development of novel flax bio-matrix composites for non-structural and structural vehicle applications [PDF]

, 2015
The use of natural fibres (e.g. flax, hemp etc.) instead of synthetic fibres (carbon and glass etc.) as composite reinforcements not only benefits the environment, but also provides economical lightweight products for transports.

Numerical analysis of debonding behavior of FRP sheets bonded to concrete focusing on mortar skin

Structural Concrete, EarlyView.
Abstract This paper proposes a novel simple method for finite element analysis (FEA) to simulate the debonding behavior of fiber‐reinforced polymer (FRP) sheets bonded to concrete. This study focuses on the mortar skin of the concrete surface layer, which fails during FRP sheet debonding.

Enhancing hydrophobicity and corrosion resistance of epoxy resin coatings using KH570-ZrO2 nanoparticles

Polymer Testing
Epoxy resin has excellent adhesion, mechanical strength, environmental adaptability and corrosion resistance. As a concrete coating, it can effectively seal internal pores, prevent the penetration of water and corrosive ions. However, the epoxy resin has

Evaluations of the effectiveness of the near‐surface mounted steel materials in strengthening short RC wall‐like columns with openings

Structural Concrete, EarlyView.
Abstract In practice, reinforced concrete (RC) wall‐like columns often have openings to facilitate building services, which creates stress concentrations around the opening, resulting in the weakening of their load‐carrying capacity. This study proposes innovative strengthening methods using near‐surface mounted (NSM) incorporating steel materials to ...
