Maximum mechanical reinforcement

Given the nature of a polymer (i.e., nd th maximum mechanical reinforcement by a completely dispersed nanofiller will be limited by the polymer-filler interfacial strength. For example, in the case of PE and PP... 

Design criteria and nanomaterial properties for maximum mechanical reinforcement... 

The efficacy of nanomaterials as reinforcing agents depend on several factors such as nanomaterial morphology, aspect ratio, surface area, functionalization state, nanomaterial aggregation, and changes in aoss-linldng density of polymer matrix. Maximum mechanical reinforcement is achieved as a result of a complex interplay of these several factors. In this section, we will review these parameters and discuss strategies for maximum mechanical reinforcement.

Plastics, both thermoplastic and thermosetting, will deform under static load. This is known as creep. For this reason those materials whose prime function is mechanical are generally reinforced with mineral filler or short fibres, or else oriented by drawing. Many components have a limit on acceptable deformation, and the predicted creep strain at the end of life will be fed back to define either a maximum load, or mechanical dimensions large enough for the component to remain within the limitations on strain. Creep becomes more pronounced at higher temperatures. 

Due to the fact that the mechanical properties of unidirectional, continuous-fiber-reinforced composites are highly anisotropic, maximum effectiveness is often achieved by making laminate composites of multiple layers. This is particularly true of carbon and Kevlar -reinforced polymers, which will be described in Section 5.4.3.
