West System Inc. (Bay City, Mich.) is offering its 727 Episize Biaxial E-Glass tapes and the 737 and 738 Episize Biaxial E-Glass fabrics. The 727 tape is ideal for marine fiberglass projects and can create strong joints. Two layers at a ±45° fiber orientation are held together by light stitching. The flat, non-crimped fibers help reduce print-through and provide higher stiffness than woven fabrics, says the company. The tape is recommended for repairs, tabbing and reinforcing. The 737 and 738 fabrics are 15-oz non-woven E-glass, with two layers at a ±45° fiber orientation. The 737 achieves high fiber-to-resin ratio with hand wetout, suitable for both composite repairs and general reinforcement. The 738 has the same qualities as the 737 but with a 0.75 oz/ft2 mat backing, yielding about 22 oz/yd2 total fabric weight.
