Uses of low molecular mass, non-evolutive polyamide resins for making composite articles are described. Articles obtained from such resins having good mechanical properties, such as rigidity, breaking load, impact resistance, and fatigue behavior in particular, even when the articles are manufactured according to cycles shorter than those usually used, and without any processing before or after the manufacture of the composite articles, are also described.

Composite polyamide article

High fluidity polyamides are used for the impregnation of reinforcing cloth materials, namely, industrial fabrics, which impregnated cloths are converted into composite shaped articles.

Composite polyamide shaped articles

The use of a polyamide including hydroxyaromatic units in order to increase the acid resistance of a polyamide composition is described. A polyamide composition comprising a polyamide that includes hydroxyaromatic units and use thereof for the manufacture of various plastic articles such as, for example, calibrated particles or injection-molded parts is also described. Such a composition is especially useful in the field of the recovery of slurries, liquids and gases present in underground reservoirs, and in particular in the field of the extraction of hydrocarbons, such as crude oil or natural gas.

Polyamide composition

The present invention relates to a novel process for the manufacture of nonwoven surfaces. It relates more particularly to a process for the manufacture of nonwoven surfaces by the process of direct melt spinning of continuous filaments arranged in the form of a sheet. This process employs a composition based on a thermoplastic polymer exhibiting an electrical conductivity sufficient to prevent the formation of electrostatic charges or to allow their removal during the spinning process.
