Poly (arylene sulfide sulfone) (PASS) is the thermoplastic engineering resin with excellent integrated performance. However, PASS have high melt viscosity and is prone to be oxidized at high temperature. It means that the melt processing is difficult for PASS. In this paper, glass fiber cloth reinforced PASS (PASS/GFC) laminate was prepared via solution impregnation. PASS resin was dissolved in N-methyl pyrrolidone (NMP). Then the glass fiber cloth was impregnated with the PASS/NMP solution followed by the extraction of NMP, and the prepregs was obtained. The prepregs were molten and laminated and the properties of laminates were tested. SEM observation of the fracture surface showed that the resin can penetrate into the fiber bundle and the adhesion between fiber and matrix is good. The tensile and impact strength was increased with the increasing glass fiber content. The tensile and impact strength of PASS/GFC laminate are 221 MPa and 74.3 KJ/m2 with 75 wt% GF content. The flexural strength reach the peak, 348 MPa, with 65 wt% glass fiber. Moreover, the carbon nanotubes (CNTs) was introduced into the PASS/NMP solution to improve the properties dominated by the matrix. The mechanical properties of composite with 75 wt% glass fiber were improved with the increasing content of CNTs. The tensile, flexural and impact strength are 271 MPa, 416 MPa, and 108 KJ/m2 with 2 wt% CNTs. And the further addition of CNTs deteriorated the strengths of laminates.
