Filler short glass fibers

Friedrich and Voss 24 copolyester Investigated effect of fillers (short glass fiber, carbon fiber, mineral, graphite flake) on fracture and wear properties. 

Fibrous fillers are now gaining more importance over particulate fillers due to the high performance in mechanical properties. The influence of fiber diameter on the tensile behavior of short glass fiber on polyimide was reported [95], At higher concentrations thick fibers seem to be more advantageous probably because of the... 

To meet fabricated dimensional tolerances different approaches are used. They include use of specific fillers and reinforcements and process control (Chapter 3). Popular filler used is short glass fibers (Chapter 15). Over 50wt% of all types of glass fibers used with different plastics and by different processes are used in injection molding compounds. Table 2.2 shows the shrinkage of different unreinforced plastics ad glass fiber reinforced plastics based on ASTM testing procedures. 

Fillers used in large quantities to reinforce plastics are alumina (aluminum oxide), calcium carbonate, calcium silicate, cellulose flock, cotton (different forms), short glass fiber, glass beads, glass spheres, graphite, iron oxide powder, mica, quartz, sisal, silicon carbide, dtanium oxide, and tungsten carbide. Choice of filler varies and depends to a great extent upon the requirements of the end item and method of fabrication. 

Allyl resins are also easily molded and fabricated. The allyl resins have excellent dimensional stability, offering very low after-shrinkage (on the order of 0.1%). The largest commercial product is filled with short glass fiber filler, which combines moldability in thin sections with extremely high tensile and flexural strengths.

SPS is a semicrystalhne polymer with a glass transition temperature (Tg) of 100°C and a crystaUine melting point (Tm) of 21Q°C. SPS readily accepts fillers, and by compounding with short glass fibers, the heat deflection temperature can be increased to close to the crystalline melting point. A comparison of the Tg and Tm of SPS with other engineering thermoplastic materials is shown in Figure 15.1. 

Partially resistant in course of time, there is a distinct deterioration in mechanical properties and a change in weight in many cases a short exposure may be considered allowable Ertalon 66-GF30 Quadrant EPP Filler 30% Glass fiber...
