Manufacture and Mechanical Properties of Nanocomposite Laminates

This work mainly aims to manufacture nanocomposite laminates at first. The prepreg AS-4 graphite/PolyEtherEtherKetone laminates were used to make a 16-layered APC-2 laminate of 2 mm thick via curing the modified diaphragm. The nanoparticles of Silica (SiO2) were uniformly spread on the specific interfaces totally about 1-3% by weight of a laminate by sol-gel method. Second, by the results of me...

Hygrothermal Aging of Polyimide Matrix Composite Laminates

Two polyimide-matrix systems were subjected to a series of hygrothermal aging experiments at various temperatures and relative humidities. For each aging condition, we measured the microcracking fracture toughness as a function of aging time. The toughness decreased with time. The rate of decrease increased with temperature and relative humidity. All experimental results could be fit to a simpl...

Damage Assessment of Drilled Hybrid Composite Laminates

Hole drilling operations are common in fibre reinforced plastics FRP’s to facilitate fastener assembly to other parts in more complex structures. As these materials are non-homogeneous, drilling causes some damages, like delamination, for example. Delamination can be reduced by a careful selection of drilling parameters, drill material and drill bit geometry. In this work two types of laminates...

Tool Effects on Hybrid Laminates Drilling

Fibre reinforced plastics are increasing their importance as one of the most interesting groups of material on account of their low weight, high strength and stiffness. To obtain good quality holes, it is important to identify the type of material, ply stacking sequence and fibre orientation. In this paper, the drilling of quasi-isotropic hybrid carbon+glass/epoxy plates is analyzed. Two commer...
