Abstract
In a layered carbon fiber reinforced thermoplastic polymer (CFRTP) composite composed of 3 cross-weave carbon fiber (CF) cloth sheets between 4 polypropylene (PP) mats, [PP]4[CF]3 (55 vol%-CFs), effects of: (1) factory provided sized CF (sizing film (SF) coated CFs with nano-scale rough surface after anodic oxidization), and (2) electron beam irradiation (EBI) under protective nitrogen gas atmosphere to SFF-CF (sizing film free and bare CFs with nano-scale rough surface after anodic oxidation) prior to assembly with PP layers and hot-press, on bending strength (σb) at median-accumulative probability (Pf = 0.50) were investigated. Firstly, the sizing film (SF) improved the σb 36% from 38 to 52 MPa over that of SFF-CF. Improvements by the SF itself could be explained by acting as a buffer adhering to both PP and CFs increasing fiber pullout and delamination resistance with friction force (Ff) of entangling of PP and SF polymer on CF with weak molecular bonds at SF/CF interface, larger than that of point contacts of PP and CF at PP/CF interface. Secondly, applying 0.22 and 0.30 MGy-EBI treatments to CF surfaces with and without sizing film under protective N2 gas atmosphere prior to assembly and hot-press improved σb, 6% from 52 to 55 MPa and 45% from 38 to 55 MPa, respectively. Improvements of CFs with and without sizing film treated by EBI in N2 gas can be explained by strong covalent bonds formation at PP/CF interface as direct (CF:\(\boxed{\text{C:C}}\):PP), and indirect (CF:\(\boxed{\text{N:N}}\):PP and CF:\(\boxed{\text{C:O:C}}\):PP) contacts induced by N2 gas molecules and trace gaseous impurities, in addition to weak molecular bonds CF–(H2O, N2, O2)–PP.
