Abstract Modern production of fiber reinforced composites via the preforming process is widely used in industry. A common way to create dry, semi-finished products forming or draping a textile into three-dimensional component geometry. The punch and die often for resin transfer molding (RTM) composite manufacturing. Due major influence step on later mechanical performance component, detailed kn...

A macroscopic finite element model has been established to investigate the forming-induced wrinkling behaviour for bi-axial fabrics. Results indicate that using a linear bending with constant stiffness produces unrealistic wrinkle patterns in fabric plies. non-linear more accurate forming induced compared experimental data, since parameter is varied as function of applied load account onset fib...

The methoxy- and fluoro-derivatives of meta-nitrophenylacetic acid (mNPA) chromophores undergo photodecarboxylation with comparable quantum yields (Φ) to unsubstituted mNPA, but uncage at red-shifted excitation wavelengths. This observation prompted us investigate DPAdeCageOMe (2-[bis(pyridin-2-ylmethyl)amino]-2-(4-methoxy-3-nitrophenyl)acetic acid) DPAdeCageF (2-[bis(pyridin-2-ylmethyl)amino]-...
