“…Among a variety of fillers, glass fibers are extensively preferred owing to their ability of increasing the stiffness and heat resistance of the composite as well as their relatively low processing costs [10]. Addition of glass fibers into PA 66 matrix up to a certain ratio leads to a large amount of improvement in the mechanical properties [11][12][13][14][15][16][17][18].…”

In this study, the effect of hexagonal boron nitride (hBN) and modified (carboxylic acid functionalized) multi-walled carbon nanotubes (MWCNTs-COOH) on tensile and flexural behaviour of 30% short glass fiber reinforced Polyamide 66 (PA 66/30SGF) is investigated. Initially, MWCNTs-COOH, hBN and MWCNTs-COOH/hBN are mechanically mixed with PA 66/30SGF granules in ethanol and stirred via a magnetic stirrer for one hour. After ethanol evaporates, MWCNTs-COOH, hBN and MWCNTs-COOH/hBN integrated granules are conditioned in an oven and the obtained granules are transferred to the plastic injection moulding machine for the fabrication process of specimens. Thus five types of specimens are produced; and their mechanical behaviors are examined by Instron 5982 test machine. The test results show that elastic modulus and flexural properties of PA 66/30SGF are improved with the addition of MWCNTs-COOH, hBN and MWCNTs-COOH+hBN.

SYNOPSISThe recent high demand of thermoplastic composites has induced an extensive experimentation and utilization of polyamides as thermoplastic sheet composites. The hand layup technique was used for the preparation of the glass fiber polyamide composites studied here. The percentage crystallinity of the composites was determined with a variety of techniques such as differential thermal analysis (DTA) , wide-angle X-ray diffraction (WAXD) patterns, and density measurements. Glass transitions ( T8) and melting temperatures (T,) were determined with DTA and dynamic mechanical thermal analyzer ( DMTA) measurements. Finally, the mechanical properties ( stress-strain curves and compression tests) were investigated and the results were correlated to the glass fiber content, the void content, and the percentage of the comnomer unit (caprolactam and laurolactam) in the polyamide composite. 0 1994 John Wiley & Sons, Inc. INTRODUCTIONThe currently predominant matrix resins for composites continue to be the thermosetting polymers due to their low viscosity (especially in the liquid state) and their facile impregnation into the fiber bundle before the occurrence of curing.',' However, a number of arising disadvantages connected to the production of thermosetting composite resins such as the limited shelf life of the polymers, variation of composite properties, Iong curing times, limited recyclability, and inadequate impact properties have recently oriented more research work toward the utilization of the thermoplastic c0mposites.2,~The following methods have been used for the production of thermoplastic long-and short-fiber composites: extrusion, solvent impregnation, ' hand l a y~p ,~ film stacking, melt fluidized impregnation of expanded fiber bundles,' deposition of a polymer powder/fiber mixture from a water-* To whom correspondence should be addressed at Osaka National Research Institute, AIST, Functional Polymer Section, 1- Midorigaoka, Ikeda, 563 Osaka, Japan.Journal of Applied Polymer Science, Vol. 51. 1883-1899 (1994) The present article investigates the effect of introducing short glass fibers in a series of (co)polyamides (nylon G/nylon 12).

“…These are added to alter mechanical properties of the base material, thermal stability, electrical and magnetic properties, burning resistance, and many times to reduce the cost when the mechanical properties are not so critical. Tensile strength and Young's modulus of PA-6,6 increase by increasing the glass fibers content, 15 but this also increases the brittle to tough transition temperatures of the composites, which is a disadvantage. So their effect is opposite from the addition of a rubber.…”

Rubber toughening of glass fiber reinforced nylon‐6,6 with functionalized block copolymer SEBS‐g‐MA

ABSTRACT:The toughening of glass fiber reinforced nylon-6,6 (PA-6,6) by using the functionalized triblock copolymer styrene-(ethylene-co-butylene)-styrene, grafted with maleic anhydride (SEBS-g-MA) was examined. Blends containing 2.5, 5, 7.5, 10, and 12.5 wt% copolymer were prepared by melt blending in a single-screw extruder. Emphasis was given to the study of mechanical properties in comparison with morphology and thermal properties of the aforementioned samples. Although the amount of SEBS-g-MA that was added in PA-6,6 was not enough to produce a super-tough material, a significant increase in the resistance to crack propagation and impact strength was observed in all blends. This behavior was proportional to the amount of SEBS-g-MA that was added for samples having up to 10%, rubber, while additional amounts seem to have no further effect. A small decrease in tensile strength was also observed. From FTIR spectroscopy and DSC analysis it was shown that the grafting extent of SEBS-g-MA to PA-6,6 was very low.
