Carbon-fiber-reinforced plastics are composite materials with record-high specific strength, which depends on the efficiency of stress redistribution between reinforcing fibers by polymer matrix. The problem is accurate assessment adhesion in carbon fiber–polymer matrix system since it affects overall strength composite. This paper provides a novel electrochemical method for determining estimat...

forms of radioactivity is apparent when the corticosteroid binder is purified to homogeneity by a series of column Chromatographie fractionation procedures. The binder for 3-methylcholanthrene also has a molecular weight identical to that of the corticosteroid binder as determined by calibration on Sephadex G-75 columns and by sedimentation velocity experiments in the analytical ultracentrifuge...

Strain hardening cementitious composite (SHCC) is a special class of ultra-ductile material which has autogenous self-healing capability due to its intrinsic tight crack widths. To further improve healing ability, agent (HA) can be incorporated in SHCC, enabling it also the autonomous mechanism. In this study, effects adding bacteria-embedded polylactic acid (PLA) capsules on mechanical propert...

A new material system that can produce very high green strength and green density has been developed for conventional compaction processing. The system, which uses a zincless lubricant, is based on the optimization of the bonding mechanism and binder chemistry. This approach permits the bonding of copper particles in a FC-0208 mix. Examples of the binder-treatment of FN-0208, Ancorstee145P, and...

This study investigated the effect of high asphalt binder replacement for a low N-design asphalt mixture including RAP and RAS on performance indicators such as permanent deformation, fracture, fatigue potentials, and stiffness, was studied. An experimental program included complex modulus, fracture, overlay reflective cracking resistance, wheel track permanent deformations, and push-pull fatig...

This paper focuses on the effect of polypropylene (PP) fibers mechanical properties and thermal conductivity fly ash-based geopolymer foams. Class C Fly ash (FA) was used as a binder material. A mixture sodium silicate (SS) hydroxide (SH) an alkaline activator binder. The foams were prepared mechanically by mixing foaming agent with distilled water at high pressure. added to admixture volumes 4...

The paper presents a comparative analysis of methods and results calculating the physical mechanical characteristics single-layered multi-layered polymer composite materials (PCM). object study is which consists epoxy binder carbon fiber reinforcements. principle multiscale modelling applied to determine composite. Within framework this study, representative volume element (RVE), structure corr...
