Style 7781 glass fabric (550 yarn), an 8-harness satin weave that drapes readily over compound curvature, in an F141 polyester matrix. Glass/polyester is the low-cost commercial laminate: easy to process at room temperature, forgiving in open moulds, and adequate where loads are modest. It is the standard for marine hulls, tanks and pipework, and industrial panels, rather than for weight-critical aerospace structure. The handbook characterises it from -65 °F to 300 °F, consistent with moderately elevated service. MatWorld carries 66 tensile, compressive and shear curves for this system, digitised from MIL-HDBK-17-2F Volume 2 (US Government work, public domain).
