[ABSTRACT] Chemical compositions and fiber measurement of virgin and recycled fibers from three sources were determined. Results revealed that virgin southern pine fiber had highest slcohol-benzene extractive and lignin contents and lowest holoand alpha-cellulose content among the three fiber types. Fiber length distribution of virgin fiber was less sensitive to disintegration. Effects of recyc...

Composite materials play a vital role in many industrial applications. Researchers are working on fabrication of new composite materials worldwide to enhance the applicability of these materials. In view of this, the objective of the present work is to analyze the effect of nanoclay content on the mechanical and morphological behavior of S-glass fiber, reinforced in Polyester with nanoclay as f...

In the present paper, a study of the effects of fabric weight, fiber cross-sectional shapes (round, hollow and trilobal) and presence of reinforcing material on the compression properties (initial thickness, percentage compression, percentage thickness loss and percentage compression resilience) of polyester needle punched industrial nonwoven fabrics is presented. It was found that for fabrics ...

Recently, the use of recycled tyre polymer fiber derived from waste tires as a concrete reinforcement has received great deal attention. The is promising additive to for building materials which require resistance against cracking. In this work, effect treated and untreated on properties sand was studied. It shown that consists mainly different fractions crumb rubber, fiber, metal fiber. main c...

Total reflection X-ray fluorescence (TXRF) spectrometry was applied to a forensic discrimination of single polyester fibers. In non-destructive direct measurement 5 mm long fibers used for references, trace metallic elements such as Ti, Sb, Ge, Mn, and Co, found in additives catalyst residues, were detected using benchtop TXRF spectrometer. The individual elemental compositions the identified, ...

this work investigates the feasibility of using recycled high density polyethylene (rhdpe), recycled polypropylene (rpp) and old newsprint fiber (onp) to manufacture fiber reinforced composites. the boards were made through air-forming and hot press. the effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...

This paper investigated the moisture absorption, mechanical behavior and the dielectric performance of hybrid and non-hybrid polymeric composites. Hand lay-up technique was used for processing carbon; glass reinforced polyester resin composites (non-hybrid) and carbon-glass/polyester hybrid composites with various fiber configurations. The maximum resistance of water absorption was obtained for...
