Glass composition with higher mechanical performance than E-glass, used in the "leading-edge" sectors, including aircraft, space and defense, sport and leisure industries, transport and ballistic armors.
A collection of parallel strands (assembled roving) or parallel continuous filaments (direct roving) assembled without intentional twist (according to ISO/DIS 13922).
Woven or non-woven structure in which the yarns are regularly and widely spaced.
Secondary sizing or warp size
Chemicals applied to the warp yarn to improve strand integrity and abrasion resistance to withstand additional textile processing.
A large spool onto which yarns or strands pulled from a creel are wound.
A continuous element, directly usable for textile operation, made with either:
- A given number of continuous filaments (one or several strands) held together with twist
- A number of discontinuous filaments, held together with twist (according to ISO/DIS 13922)
Mixture of chemical products applied to continuous or discontinuous filaments during their manufacture. A plastic size is a product designed to obtain a good bond between the surface of the fiber and the matrix resin. It generally contains ingredients that facilitate certain operations of conversion or application (winding, chopping, etc.). A textile size is a product designed to facilitate subsequent textile operations (twisting, folding, weaving, etc.).A textile plastic size is a product designed either to facilitate subsequent textile operations or to promote the bond between the surface of the fiber and the matrix resin (according to ISO/DIS 13922).
Operation in which the secondary size, also called warp size, is applied to yarns from several section beams. The sheets are then dried and wound on a beam to make up the loom beam.
A tubular structure with a collapsed width not exceeding 100 mm (according to ISO/DIS 13922). Also called tubing.
A continuous assembly of slightly bonded discontinuous filaments in a practically parallel arrangement (according to ISO/DIS 13922).
A yarn made of two ends of yarn bound together pneumatically.
A fiberglass strand repeatedly doubled back on itself to form a roving, sometimes reinforced by one or more straight strands (according to ISO/DIS 13922).
Yarn spun from discontinuous filaments (according to ISO/DIS 13922).
An assembly of simultaneously produced parallel continuous filaments, slightly bonded and without intentional twist (according to ISO/DIS 13922).
