Abstract
A translucent or transparent composite flexible sheet includes at least one reinforcing layer comprising high tenacity yarns; and a fluorinated polymeric film which is translucent or transparent to visible light, which is integral with the reinforcing layer. The reinforcing layer is a textile with a light transmittance of more than 40%, and includes high tenacity yarns based on an aromatic block polyester with a Young's modulus of more than 50 GPa. The yarns have a sheath of material which blocks ultraviolet radiation.
Claims8
A composite flexible sheet which is translucent or transparent, having a light transmittance of more than 45%, comprising:
- at least one reinforcing layer comprising high tenacity yarns;
- and
- a polyvinylidene fluoride film which is translucent or transparent to visible light, which is integral with said reinforcing layer;
- said flexible sheet being characterized in that the reinforcing layer is a textile comprising high tenacity yarns based on an aromatic block polyester having a Young's modulus of more than 50 GPa, each of said yarns being completely covered by a sheath of material which blocks ultraviolet radiation, said flexible sheet having a reduction in its tensile strength of less than 10% after having undergone a fold test in accordance with the standard ASTM D4851;
- and
- wherein said at least one reinforcing layer and said polyvinylidene fluoride film are co-laminated together.
