The composite industry was launched in the early 1960s with the development of fiberglass, which consists of short glass fibers in a matrix of some thermoset resin. Fiberglass composites are tough, lightweight, and inexpensive to... 

Micromechanical modeling and available experimental evidence indicates that the composite toughness, KIc (composite), can be described as the sum of the matrix toughness, KIc (matrix), and a contribution due to whisker toughening, AKIc (whisker reinforcement).1,23 In other words,... 

From these results, it is clearly shown that particle size is one of the major parameters controlling the CaC03/PP composite fracture toughness. Surface treatment contributes to better particle dispersion, and also to lower particle - matrix interaction [24]. 

Dual phase continuity offers many advantages, because rubber/plastic compositions yield tough, leathery materials. Many of the compositions described above, for example, contain two continuous phases, with cylinders of polystyrene meandering within the polybutadiene matrix. Since all IPN s are crosslinked, it may be that their greatest advantage will lie in products which are leathery or rubbery, but can not be permitted to flow. 

We observe that the composite toughness W = W /V can be increased, relative to the matrix toughness, by the addition of fillers when they are treated with SIC and TTS In the case of untreated beads, on the other hand, composite toughness always decreases with increasing 0 and is lower than matrix toughness. 

The subscripts c, m, and f refer to the composite, matrix, and reinforcement, respectively. Increases in fracture toughness are predicted by...
