Comparative Material Properties
The choice of reinforcing materials is determined by the demands placed on the product. Glasforms offers a variety of reinforcing options to provide the optimum balance of cost and performance for the most demanding applications. Glass fiber reinforced plastics either in a mat/roving (MR-GFRP) or unidirectional (U-GFRP) reinforcement are most common. The fiber content and orientation is the primary factor in properties as exhibited by the differences between the two GFRP products. We also offer high performance reinforcements
such as unidirectional carbon (U-CFRP).
