％の割合で複合化することが望まれる。In the present invention, the excellent characteristics of the high-strength / high-elasticity polyethylene fiber, that is, the lightness, light resistance, abrasion resistance, and chemical resistance are not impaired, and the most significant drawback is In order to provide a synthetic resin reinforced composite fiber cloth with sufficiently improved delamination,
The highly elastic polyethylene fiber is preferably compounded at 30 to 95% by weight, more preferably 40 to 80% by weight, and the wholly aromatic polyamide fiber is preferably compounded at 70 to 5% by weight, more preferably 60 to 20% by weight. It is desired to do.
