In this paper, static and dynamic tensile tests of woven fabric reinforced plastic composites were carried out and strain rates from 1×10−3[1/s] to 1×102[1/s] were loaded under two tensile directions of 45-degree and 0-degree to the fabric directions with a servo hydraulic testing machine. The specimens of CFRTP, CFRP, GFRTP and GFRP were composed of respective fibers fabrics of carbon and glass and two different matrix resin of PA6 and epoxy. All of the specimens were fabricated with VaRTM process. The experimental results for the strength of 45-degrees specimens depended on the strain rates. Fracture strain of GFRTP and GFRP 45-degress specimens were not showed strain rates dependency. However, the fracture strain of CFRTP and CFRP declined with increasing strain rate. Absorbed energy of CFRTP and GFRTP 45-degrees specimen showed twice the value compared to the CFRP and GFRP in strain rate 10[1/s]. From the above results, strain rate dependency of strength, fracture strain and absorbed energy of FRTP and FRP by using woven fabric 45-degrees specimen were affected by reinforced fiber and matrix resin.
