Short fibers fibrous fillers

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... 

Sperling has proposed a classification of PCM which is more complex, and which considered details of a great number of compositions which we do not intend to discuss in our book. Having no claim to full classification, we wordd hke to indicate that our classification, presented above, gives a rather comprehensive idea as to what materials shordd be related to PCM. Our principle is based, first of all, on the dimensional parameter of components introduced into polymer matrix disperse particles, short cut fibers, anisotropic fibrous fillers, including fabrics and disperse pol5mieric particles. 

Composites are engineered materials that contain two or more constituents with different properties that remain distinct from one another within the structure. POCs are a subset of the larger polymer composites group. The increased synthesis of POCs with different additives is necessary to satisfy the industrial demand that cannot be fulfilled by pure polymers. Additive materials can be classified as micro-and nanofillers depending on the applications of the composites. The fillers may be further subdivided as natural (plant fibers) or synthetic (glass fibers, CNT, etc.), different shapes (long or short length), flaky, fibrous, and spherical or disk-like [6]. The conventional addition of filler materials lowers the cost and improves the... 

There are many fibers of S3mthetic origin, most of them spun or extrusion-drawn semicrystalline polymers (e.g., polyolefins, polyamides, polyesters), which are not used as fillers for polymers. The main reason is that, for a material to play a potential reinforcement role as a filler for polymer, large differences in certain key properties must exist between the filler and the polymer matrix. It follows that only three types (or classes) of fibrous products can be considered as valid short synthetic fibers candidates for polymer reinforcement glass fibers, carbon fibers and aramid fibers.
