Fabric selection is critical when designing composite structures. Fiberglass reinforcement is an all-purpose choice for your composite project. Fiberglass is
the most widely used reinforcement and generally is the least expensive. Fiberglass fabric has been used since the 1950's, and much is know about its
properties. It is relatively lightweight, has moderate tensile and compressive strength, is tolerant of both damage and cyclical loading, and is easy to
handle and machine.
Woven Fiberglass Fabric is an excellent choice for selective reinforcement. In woven fabrics, the fiberglass fibers
are bundled into yarns. These yarns are woven into several weave patterns, and each pattern provides strength in the direction of these yarns. Fiberglass Mat is one of the most popular forms of reinforcement. Fiberglass Mat typically consists of randomly oriented
filaments of glass that are loosely held together with a resin-soluble binder. Often used in molds, Fiberglass Mat can quickly build thickness and provides
strength in multiple directions. Stitched Fiberglass is a fabric style in which the fiberglass yarns are stitched
instead of woven. This means that there is no crimps in the yarns. Stitched Fiberglass fabrics are easy to handle, are quick to wet out, and are great for
controlling the strength properties of a laminate.
