REINFORCING FIBROUS MATERIAL Abstract of the Disclosure Disclosed is a reinforcing fibrous material having an improved adhesion, which consists essentially of a surface-treated, molecularly oriented, silane- crosslinked ultra-high-molecular-weight polyethylene fiber, wherein when the measurement is conducted under restraint conditions by using a differential scanning calorimeter, the crosslinked polyethylene fiber has at least two crystal melting peaks (Tp) at temperatures higher by at least 10 C than the inherent crystal melting temperature (Tm) of the ultra-high-molecular- weight polyethylene determined as the main peak at the time of the second temperature elevation, the heat of fusion based on these crystal melting peaks (Tp) is at least 50% of the whole heat of fusion, and the sum of heat of fusion of high-temperature side peaks (Tpl) at temperatures in the range of from (Tm + 35)°C to (Tm + 120)°C is at least 5% of the whole heat of fusion, and wherein the crosslinked polyethylene fiber has a surface containing at least 8 oxygen atoms, especially at least 10 oxygen atoms, per 100 carbon atoms, as determined by the electron spectroscopy for chemical analysis.
