Abstract The effects of the length of glass fibers on the toughness of long glass fiber reinforced polyphenylene sulfide (PPS) composites (PPS-LFT), made by the pulltrusion process, were studied with regards to both the molding V notched specimen and the cutting V notched specimen. Toughness was excellent on the molding V notched specimen. By observing the fracture morphology of the molded V notched specimen, it was found that a crack was formed, due to a slip or debonding at the fiber surface. The crack was propagated along the fiber, due to the pulling out of fibers from the matrix polymer. Both the maximum load and the fracture energy increased with increasing length of the glass fiber, because the resistance created by pulling out the fibers increased with increasing fiber length. In the case of PPS-LFT, it is understood that toughness improved because the slip between the fiber and the resin occurs before the excessive elastic strain energy is stored.

In this paper, we investigated the effects of a coupling agent (KH560) on the mechanical properties of long glass fiber (LGF) reinforced polyphenylene sulfide (PPS) composites. The LGF reinforced PPS composites were prepared utilizing our self-designed mold. It’s found that KH560 was beneficial for improving the mechanical properties of the composites. Meanwhile, the fiber lengths of glass fibers in the original injection molded sample and near the fracture surface were measured under the optical microscope. Comparing to the untreated sample, the sample with KH560 possessed higher proportion of fiber length on 0.75-1.25 mm. It suggested that KH560 could protect glass fibers from broken. Meanwhile, near the fracture surface, two composites possessed similar proportions of fiber length on 0-0.75 mm. That indicated KH560 improved the interfacial bonding between glass fiber and PPS. Scanning electron microscopy (SEM) images showed that more resin adsorbed on the fiber surface, which was consistent with the above phenomena.

Polyamide 1010

Influence of lubricants such as montan waxes and fatty acid esters, on properties of glass fiber reinforced composites based on polyamide 1010. Composites with 40 % wt. glass fibers were obtained on twin-screw extruder, while the fiber breakage occur. Fiber length distribution were measured. It is shown, that adding of 0.5 % wt. of lubricants increase content of glass fibers longer than 2 critical length and improve mechanical properties.

Abstract VERTON OF-700-10 is a long glass fiber reinforced polyphenylene sulfide. It has been engineered to maximize the benefits of long fiber reinforcement while maintaining the ease of processing and good fiber despersion associated with conventional short fiber reinforced compounds. Impregnation of the fibers with the resin is by pultrusion rather than the usual compounding extruder. This enables a high level of impregnation to be achieved without damaging the fibers. This datasheet provides information on tensile properties as well as fracture toughness. It also includes information on casting. Filing Code: Cp-9. Producer or source: ICI Advanced Materials.

AbstractIn this study, an injection molding machine with a low-fracture-fiber mechanism was designed with three stages: a plasticizing stage, an injection stage, and a packing stage. The fiber-fracture behavior is observed under the screw (plasticizing stage) of low-compression/shear ratio for the ultra-long fiber during the molding process. The molding material employed in this study was 25-mm-ultra-long-glass-fiber-reinforced polypropylene (PP/U-LGF). In addition, a thickness of 3 mm and a width of 12 mm spiral-flow-mold were constructed for studying the melt flow length and flow-length ratio through an experiment. The experimental results showed that the use of an injection molding machine with a three-stage mechanism decreased the fiber length when the screw speed was increased. On average, each fiber was shortened by 50% (>15 mm on average) from its original length of 25 mm. Longer glass fibers were more resistant to melt filling, and as the fiber length was reduced, the mixing between the melt and glass fibers was improved. Thus, the melt fluidity and fiber ratios were increased. In addition, the mixing/flow direction of the melt had an impact on the dispersion and arrangement of glass fibers, thus the tensile strength of PP/U-LGF increased.

This paper deals with the mechanical and thermal behavior of glass and basalt fiber reinforced concrete. Two different composites were studied containing either basalt or glass fibers. Fiber ratios were selected as 1%, 1.25% and 1.5% for glass fiber; 0.3%, 0.4% and 0.5% for basalt fibers. Fiber length was preferred as 12 mm and 24 mm. The addition of basalt fiber had very limited effect on the compressive, flexure and thermal conductivity properties compared to the glass fiber reinforced composite. The results also showed that composites having fibers with the length of 12 mm had better mechanical properties. Heat transfer simulation of the composites were also conducted. It was obtained that both fibers with the length of 12 mm had very close results on the heat transfer studies.
