Abstract: The present invention relates to a molding composition comprising, by weight:



a) 20% to 60% of at least one long-chain aliphatic polyamide having a number of carbon atoms per nitrogen atom of greater than or equal to 9,
said at least one polyamide having an inherent viscosity in solution of less than or equal to 1.3, as determined in accordance with the standard ISO 307:2007 at a temperature of 20° C.,
b) 40% to 75% of glass fibers, and
c) 0% to 5% by weight, by weight of at least one additive,
the sum of the proportions of each constituent of said composition being equal to 100%,
with the exclusion of an amorphous polyamide and a microcrystalline polyamide.
