Abstract: High strength and high modulus polyethylene (UHMWPE) staple fiber paper-based composite
materials were prepared from UHMWPE staple fiber and softwood pulp via wet forming technology
combined with resin impregnation and hot pressing. The effects of base paper preparation technology and
hot pressing technology on UHMWPE fiber paper-based composite materials were then investigated. The
results showed that, under the conditions of the mass ratio of UHMWPE fiber to softwood pulp 7∶3, the
beating degree of softwood pulp 58 °SR, the mass fraction of phenolic resin solution 10%, the sizing
amount 44%, and the hot pressing process conducted at 10 MPa and 130 ℃ for 15 min, the UHMWPE
fiber paper-based composite material exhibited good properties. The UHMWPE fiber paper-based
composite material prepared from impregnated and hot pressed base paper showed a tensile resistance index of
59.11 N·m/g, which was increased by 6.9 times, a smoother surface, a low dielectric constant of ~1.97, a

dielectric loss factor of 0.45×10 and good thermal stability.
