A complete series of mechanical characterization tests has been conducted on a filament wound composite of approximately 60 vol% organic fibre in an epoxy matrix. Using, for the most part, flat-plate specimens, quasi-static mechanical properties (including elastic constants and ultimate strengths) in tension, compression, and shear were obtained. The longitudinal tensile strength was found to be equal to or above the 1380 MPa generally quoted for similar mat materials. Although tensile and compressive elastic constants were the same, the material proved to be several times stronger in longitudinal tension than in longitudinal compression, and several times weaker in transverse tension than in transverse compression. The low transverse strength (12.35 MPa) and the high in-plane shear strength (38 MPa) of this composite compared to other organic fibre/epoxy composites indicate that it may be usable only in applications where failure is controlled by longitudinal tensile properties. |
