Composite & Pre-preg Materials
Pre-preg is a term for “pre-impregnated” composite fibers where a matrix material, such as epoxy, is already present. The fibers can take the form of a weave or non-woven and the matrix is used to bond them together. The matrix is only partially cured to allow easy handling, this B-Stage material requires cold storage to prevent complete curing. B-Stage pre-preg is always stored in cooled areas since heat accelerates complete polymerization. Composite structures built of pre-pregs will mostly require an oven or autoclave to cure.
Pronat has evolved several processing capabilities using composite materials including, bias sewing panels, and cutting and chopping coated B-stage fabrics from standard roll.
