Mechanical properties of polypropylene/natural fiber composites: Comparison of wood fiber and cotton fiber

Effective mechanical properties of ‘‘fuzzy fiber’’ composites

In this paperwe investigate themechanical behavior of carbonfiber composites,where the carbonfibers are coated with radially aligned carbon nanotubes. For this purpose we develop a general micromechanics method for fiber composites, where fibers are coated with radially aligned microfibers (‘‘fuzzy fiber’’ composites). The mechanical effective properties are computed with a special extension of...

Effect of Fiber Length on Processing and Properties of Extruded Wood-Fiber/HDPE Composites

Fiber length and distribution play important roles in the processing and mechanical performance of fiber-based products such as paper and fiberboard. In the case of wood–plastic composites (WPC), the production of WPC with long fibers has been neglected, because they are difficult to handle with current production equipment. This study provides a better understanding of the effect of fiber leng...

High-Temperature Hot Air/Silane Coupling Modification of Wood Fiber and Its Effect on Properties of Wood Fiber/HDPE Composites

The surfaces of poplar wood fibers were modified using high-temperature hot air (HTHA) treatment and silane coupling agent. The single factor test was then used to investigate the performances (e.g., the change of functional groups, polarity, cellulose crystallinity, and thermal stability) of modified poplar wood fibers (mPWF) through Fourier transform infrared spectrometry, X-ray diffraction a...

Mechanical Properties of Irregular Fiber (Invited Review Paper)

Irregularities are inherent to virtually all fibers, including the conventional textile fibers, the high-performance brittle fibers and newly developed nano-fibers. These irregularities can fall into two main categories: dimensional or geometrical irregularity (external) and structural irregularity (internal). For natural fibers such as wool, diameter variation along fiber length is atypical ex...
