Short glass fibers mechanical properties

Nonoxide fibers, such as carbides, nitrides, and carbons, are produced by high temperature chemical processes that often result in fiber lengths shorter than those of oxide fibers. Mechanical properties such as high elastic modulus and tensile strength of these materials make them excellent as reinforcements for plastics, glass, metals, and ceramics. Because these products oxidize at high temperatures, they are primarily suited for use in vacuum or inert atmospheres, but may also be used for relatively short exposures in oxidizing atmospheres above 1000°C. 

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... 

With 10-40 % by weight short glass fibers (length 0.01-0.5 mm mean length of glass fibers approximately 0.2 mm) mixed into, for example, polypropylene, the mechanical and thermal properties of the material can be improved to such an extent the applications listed above, often in housings and casings, can be realized.

Mantia et al. [70] used short glass fibers to reinforce a PET/HDPE mixture (Table 16.9), which is one of the typical compositions in packaging waste. The mechanical properties of the blends, except for the elongation at break, are enhanced with the increase of glass fiber content. The addition of 20 wt % glass in PET/HDPE blends increased the tensile modulus by 50%, tensile strength by 110%, and impact strength by 70%. In addition, the heat distortion temperature of the blend was remarkably improved. 

The reinforcement of thermoplastics, notably polypropylene (PP) and polyamide (PA), with short glass fibers is a classical method to improve polymer mechanical properties. Fibers are dispersed more or less homogeneously in the polymer by melt compounding techniques such as twin screw extrusion to produce compounds ready for injection molding. Molded parts benefit from the better mechanical properties of the reinforcing fibers as the fibers bear a considerable part of the load applied to the composite structure.

The NaOH-extracted fiber iPPMA-based composites present specific mechanical properties comparable to those of analogous short glass fiber reinforced materials this can lead, in the future, to a real possibility for broom fibers to be used as alternative materials to the standard synthetic reinforcement, also owing to the fact that they are cheap, light, and biodegradable.
