A panel for a vehicle is described. The panel includes a substrate and a hardcoat layer on a surface of the substrate configured as a vehicle front-facing surface. The panel includes a first portion having a visible light transmission equal to or greater than 40% measured in accordance with ASTM D1003-00. The substrate includes a polymer composition comprising polycarbonate. A melt volume rate of the polycarbonate is equal to or less than 15 cm3/10 min, measured at 300° C. with a 1.2 kg load in accordance with ISO1133.

Panel, integrated structure, and method

The disclosure concerns methods for molding a polycarbonate containing plastic, the method including: (a) injecting a composition into a mold, the composition including (i) about 49 wt % to about 97.9 wt % of polycarbonate, (ii) about 2.0 wt % to about 50 wt % of a polycarbonate-polysiloxane copolymer, and (iii) about 0 wt % to about 1.0 wt % of at least one release agent; and (b) releasing the composition from the mold. The mold includes at least one draft angle of about 0.1 degrees to about 7 degrees. The polycarbonate blend includes a melt flow volume rate (MVR) of at least about 25 cm3/10 min as measured according to ISO 1133 at 300&#xb0; C. and 1.2 kg.
