Transparent molding compositions based on polyamides, impact modifier and short glass fibers and uses thereof

Abstract

A transparent molding composition including, by weight (with a total of 100%): (A) 35 to 84% of a polyamide mixture including: 10 to 95% by weight of at least one semi-crystalline aliphatic polyamide, whose average number of carbon atoms relative to nitrogen atoms is greater than or equal to 8; 90 to 5% by weight of at least one amorphous polyamide; (B) from over 10 to 30% of at least one impact modifier; (C) from 6 to 20% of short glass fibers; (D) 0 to 10% of at least one prepolymer; and (E) 0 to 5% of at least one additive selected from stabilizers, dyes, plasticizers, processing aids or a mixture thereof, the index of refraction of each constituent (A), (B), (C) and (D) being included between 1.500 and 1.540, and wherein said composition has no PEBA and has a dry-measured modulus at 23° C. over 1700 MPa.
