Highly oriented polypropylene fiber reinforced random PP copolymer composites were produced by film-stacking method. The reinforcing fibers were carded and needle punched and the film-stacked packages were compression molded at different processing temperatures (T=150…170°C) and holding times (t=90…600 s). For characterization of the consolidation of the composite sheets interlaminar strength was determined and further the polished sections were studied by light microscopy. Static tensile and dynamic impact (instrumented falling weight impact - IFWI) tests were performed on the specimens cut from the sheets. It was established that the best properties can be achieved when the processing conditions are 165°C and 90s. Increasing temperature and improving consolidation reduced perforation impact energy owning to better fiber/matrix adhesion and the smaller extent of delamination between the film-stacked layers.

Nmr Diffusion

Super-absorbent fiber has the property of absorbing moisture up to several thousand times its original weight, undergoing significant expansion, and eventually becoming a gel. The hydrophilic super-absorbent fiber is usually blended with hydrophobic polymer fiber to form a polymer web with the ability to attract fluid and also to hold it under pressure. Because of the confining influence of pore boundaries on molecular translation, restricted diffusion measurements on fluids in porous systems, such as the super-absorbent web, contain important information about the pore morphology. In this work, we studied the diffusion of water in a web of super-absorbent polyacrylate and polypropylene fiber. We observed restricted diffusion of the water by means of the pulsed-field-gradient spin-echo (PFGSE) NMR technique. Several mathematical models were used to interpret the data and yield estimates of the gross pore dimensions and the surface-to-volume ratio of the pores.

The graft polymerization of lauryl methacrylate (LMA) onto polypropylene fiber (PP) was investigated by using 2,2’-azobisisobutyronitrile (AIBN) as initiator. The grafting was influenced by AIBN concentration, monomer concentration, the reaction time and reaction temperature. On the basis of a detailed investigation of these factor, the optimal conditions for the grafting of LMA onto PP with the said initiator were as follows: [AIBN] = 0.015 mol/l, [LMA] = 1.25 mol/l, reaction time 240 min, reaction temperature 80 oC, in which the graft yield (%GY) of 15.7 % was obtained. Characterization of the polypropylene fiber-graft-lauryl methacrylate was done by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).
