“…There are two approaches to overcome this type of problem; a common one is to treat the fiber, and another is to operate on the matrix. The first technique is acting on UHMWPE fibers including physical and chemical methods, such as plasma treatment, corona discharge, chemical etching, irradiation‐induced grafting, and chemical grafting . The dispersion of nanoparticles such as carbon nanotubes (CNTs) and carbon nanofibers (CNFs) in the matrix is the second method to improve the adhesion between fiber and matrix.…”

Dispersed nanofiller particles could act as a mechanical interlocking between the fiber and matrix improving fracture toughness as well as the modulus, strength, thermal and electrical properties.…”

Interface interactions of fiber-matrix play a crucial role in final performance of polymer composites. Herein, in situ polymerization of glycidyl methacrylate (GMA) on the ultrahigh molecular weight polyethylene (UHMWPE) fibers surface was proposed for improving the surface activity and adhesion property of UHMWPE fibers towards carbon nanofibers (CNF)-epoxy nanocomposites. Chemical treatment of UHMWPE fibers was characterized by FTIR, XPS analysis, SEM, and microdroplet tests, confirming that the grafting of poly (GMA) chains on the surface alongside a significant synergy in the interfacial properties. SEM evaluations also exhibited cohesive type of failure for the samples when both GMA-treated UHMWPE fiber and CNF were used to reinforce epoxy matrix. Compared with unmodified composite, a 319% increase in interfacial shear strength was observed for the samples reinforced with both 5 wt % GMA-grafted UHMWPE and 0.5 wt % of CNF.

“…The X‐ray diffraction patterns of UHMWPE fiber before and after treatment are similar. There are three reflections corresponding to monoclinic lattice in addition to two reflections (110 and 200) of orthorhombic lattice on the X‐ray pattern within the interval of 19°–26° . Both degree of crystallinity of initial and treated fibers are 65.95%.…”

A novel surface modification method for ultrahigh molecular weight polyethylene (UHMWPE) fibers to improve the adhesion with epoxy matrix was demonstrated. Polyethylene wax grafted maleic anhydride (PEW‐g‐MAH) was deposited on the UHMWPE fibers surface by coating method. The changes of surface chemical composition, crystalline structure, mechanical properties of fiber and composite, wettability, surface topography of fibers and adhesion between fiber and epoxy resin before and after finishing were studied, respectively. The Fourier transform infrared spectroscopy spectra proved that some polar groups (MAH) were introduced onto the fiber surface after finishing. The X‐ray diffraction spectra indicated that crystallinity of the fiber was the same before and after finishing. Tensile testing results showed that mechanical properties of the fiber did not change significantly and the tensile strength of 9 wt % PEW‐g‐MAH treated fiber reinforced composite showed about 10.75% enhancement. The water contact angle of the fibers decreased after finishing. A single‐fiber pull out test was applied to evaluate the adhesion of UHMWPE fibers with the epoxy matrix. After treatment with 9 wt % PEW‐g‐MAH, a pull‐out force of 1.304 MPa which is 53.59% higher than that of pristine UNMWPE fibers was achieved. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.

“…Figure 8 shows the diffractogram for untreated and treated UHMWPE fibers. The XRD pattern reveals two strong diffraction peaks at 2θ around 21.6° and 24.1°, which are characterized by 110 and 200 crystallographic planes of the monoclinic phase, respectively [24]. It also shows no significant changes in the shapes of the diffraction curves, which suggests that supercritical CO 2 pretreatment and electron beam irradiation at doses less than 150 kGy do not change the crystal form of UHMWPE fibers.…”

This study introduced trimethylolpropane trimethacrylate into ultra-high molecular weight polyethylene fibers through supercritical CO2 pretreatment before the fibers were irradiated under an electron beam. Significant differences, emerging in the ultra-high molecular weight polyethylene fibers’ gel content, mechanical properties, and creep property according to their different irradiation doses, were studied through one-way analysis of variance. Regression equations were established between the irradiation dose and the gel content, breaking strength, elongation at break, and creep rate by regression analysis. A reasonable irradiation dosage range was determined after a verification experiment and the impact trends were analyzed; additionally, the sensitized irradiation crosslinking mechanism of ultra-high molecular weight polyethylene fibers was preliminarily examined. Then the surface morphology, chemical structures, thermal properties, and crystal properties of treated ultra-high molecular weight polyethylene fibers were measured. The results showed that as the irradiation dose increased, the gel content first rose and then declined; the breaking strength decreased continuously; the elongation at break increased at first and then decreased; and the creep rate originally fell and then rose before finally declining slowly. Electron beam irradiation had a significant etching effect on the fibers’ surface, and both the melting point and crystallinity decreased slightly.
