Advanced materials by design constituents of polymer matrix composites matrix the matrix properties determine the resistance of the pmc to most of the degradative processes that eventually cause failure of the structure. These processes include impact damage, delami-nation, water absorption, chemical attack, and high-temperature creep.
Polymer matrix composites (pmcs) consist of a polymer resin reinforced with fibers, an example of which is the combat helmet. Pmcs can be subdivided into two categories, based on whether the fiber reinforcement is continuous or discontinuous. Pmcs with discontinuous fibers (less than 100 mm long) are made with thermoplastic or thermosetting resins, whereas pmcs with continuous fibers usually employ thermosetting resins.
Under specific processing conditions, these composites consist of discrete nanoparticles distributed uniformly throughout the bulk of an optically transparent polymer matrix. Incorporating other chemical species as supplementary deposition agents in the synthesis process can modify these particles and produce complicated nanostructures with.
