Toughened polyamides,in the neat PA is shear yielding. Above .. excessive shear yielding can take place owing to the lowering of the yield strength at ... Unfortunately, at .. the modulus decreases strongly too. Below .. the energy absorption is mainly in the notch region and therefore mainly in the crack initiation ste

Toughened polyimides,istics which they exhibit in comparison with traditional aerospace materials such as aluminium and titanium. Possibly their most desirable attribute has concerned their ability, in certain cases, to combine high strength and stiffness with low weight. Indeed, this ability can be considered as the ma
