Abstract:

In view of the poor interfacial bonding performance between the ultra-high molecular weight polyethylene (UHMWPE) fiber and resin, this research attempted to make polypyrrole-ultra-high molecular weight polyethylene (PPy-UHMWPE) composite fibers by liquid-phase deposition polymerization, using ferric chloride as the oxidizing agent. After that, the epoxy resin micro-droplets with a diameter of 300-700μm were put on the fiber, and the pulled out experiments were carried out on the fiber / micro-drop specimens. The experimental results showed that the interfacial shear strength between the PPy-UHMWPE fiber and epoxy resin was 2 times higher than that of untreated fiber and epoxy resin. The surface morphology and structure of the fibers before and after treatment were investigated respectively by SEM, FT-IR, DSC and DMA, and it was found there is no chemical bond between PPy and UHMWPE chain in the PPy-UHMWPE fibers. PPy-UHMWPE fibers exhibited monomorph characteristics and the melt point decreased a little.
