“…However, the problem of fiber dispersion in the matrix often arises due to inertness of the fiber surface and the agglomeration of fibers due to hydrogen bonding. In order to overcome this problem, chemical or physical bonding between the fiber and the matrix is usually introduced through the addition of a suitable coupling agent [1][2] or chemical modification of the fiber surface. [3][4][5][6] Plasma treatment has also been used to create a functional group on Kevlar and hence to provide bonding with the matrix.…”

A composite of short-fiber, poly(m-phenylene isophthalamide), and thermoplastic elastomer styrene (ethylene-butylene) styrene (SEBS), was investigated. The fiber surface was modified by N-alkylation (heptylation and dodecylation) to improve their compatibility with a less polar SEBS matrix. Observation of fiber-surface morphology by SEM revealed surface roughness after N-alkylation. Nearly complete coating of the polymer matrix on the fiber was observed on a fractured surface of the composite, which is evidence for the improvement of fiber-matrix adhesion. It was found that the modulus of the composites grew with increasing fiber loading to approximately the same extent for both unmodified and modified fiber composites. Tensile strength of the modified fiber composites was found to improve significantly over that of the unmodified fiber composite. This suggests that the presence of the alkyl group on the fiber surface is responsible for an improvement of interfacial adhesion.

Long glass fiber reinforced poly(butylene terephthalate) composites (LGF/PBT) were prepared by a new process. PBT oligomers with low melt viscosity were impregnated into the reinforcing glass fiber and then grafted to the reinforcing glass fiber surface treated with a silane coupling agent during solid-state polymerization. The reinforcing glass fiber, after removing ungrafted PBT from LGF/PBT, was investigated with the result showing the presence of a grafted PBT layer on the surface of treated glass fiber. The mechanical properties of the composites were significantly improved owing to the grafting of the PBT macromolecules. The fiber length distribution and fiber arrangement in the injection molded composites were also studied and the results showed that a small amount long glass fiber could be connected at junction points in the composites, which were of benefit to the mechanical properties of the composites.

ABSTRACTNomex fabric is irradiated by an Xe 2 * excimer UV lamp (172 nm). The influence of different irradiating times and atmospheres (nitrogen and air) on the properties of Nomex fabric has been studied. The results show that the wettability of Nomex fabrics greatly improves when irradiated for 2 minutes. The scanning electron microscope (SEM) photos denote that the surface of the irradiated Nomex fiber is etched and the degree of etching in nitrogen is more severe than that in air. The XPS measurement proves that the surface of the Nomex fibers, which is irradiated in nitrogen and in air, generates carboxyl and hydroxyl groups. The results also show that the adhesive strength of the Nomex/polyethylene composite is reinforced by the irradiation.
