“…The epoxy sizing on the fiber surface could counteract the cure volume shrinkage of resin and relax the residual stress by swelling in the matrix. Broyles et al improve the fatigue resistance of composites. However, negligible differences in the shear strength, flexural strength, and static compressive strength were observed for the different interphase agents.…”

Ultra-high-molecular-weight polyethylene (UHMWPE) fibers have been modified by plasma treatment to increase adhesion in high-density polyethylene (HDPE) matrices. Results showed that surface roughness predominates for modified UHMWPE fibers, indicating that the plasma treatment favors the interaction with HDPE. Unmodified HDPE composite samples gave a lower interlaminar shear strength than did the samples that were incorporated with UHMWPE. The addition of unmodified UHMWPE fibers to the neat HDPE significantly increases interlaminar shear strengths of composites, up to 20 vol%. The oxygen concentration increased from 16.16 %to 21.99%, and the ratio of oxygen to carbon atoms increased significantly from 0.194 to 0.284 after oxygen plasma treatment for 5 minutes with a power of 300 W.

The effect of the concentration of the sizing agent on performances of carbon fiber and carbon fiber composites has been investigated. Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were applied to characterize carbon fiber surface topographies. At the same time, the single fiber strengths and Weibull distribution were also studied. The interlaminar shear strength and hygrothermal ageing test have been used to study the effect of fiber coatings on the interface of the composites. The analysis of the results shows that the sizing level is essential for improving the surface of carbon fibers and its composite performance. Different concentrations of the sizing agent have different contributions to the wetting performance of carbon fibers. Among the three concentrations of sizing agent studied (1 wt %, 1.5 wt %, and 2 wt %), the optimal sizing level is 1.5 wt %. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci 125:425–432, 2011

“…[ 49 ] In addition, the contact angle between fiber and the matrix is lowered by thermoplastic sizings thus reducing the time for impregnation and improving fiber/matrix adhesion, and the fibers can be easily compacted and compressed due to the rubbery at the exit of resin dip bath. [ 50 ] The hydrogen bond formed between sizings and matrix was proven to be beneficial to moisture resistance and mechanical properties. [ 51,52 ]…”

Continuous fiber reinforced thermoplastic composite pultrusion with in situ polymerizable methyl methacrylate: A review

Compared to thermosetting resins, thermoplastic polymers offer many advantages as fiber reinforced composite matrices, such as excellent toughness, superior corrosion resistance, weldability, and recyclable, etc. However, the processibility of thermoplastic composites is commonly considered as a challenge because of the high viscosity of polymer melts (e.g., polypropylene, polyetheretherketone, etc.), which remarkably hinders their applications. Using low viscosity and in situ polymerizable thermoplastic resins to manufacture continuous fiber reinforced thermoplastic composites have been deemed as a cost-effective emerging approach to surpass the processibility challenges. Therefore, this paper presents an overview of advancement in the engineering, high-performance and room-temperature-processible liquid methyl methacrylate (MMA) resins and their composites up to date. First, the polymerization behavior and kinetic modeling of the MMA resins are reviewed, and the effects of initiators on the polymerization are summarized. In the second part, the pultrusion process and modeling including impregnation, temperature distribution and pulling force are discussed. Next, the mechanical properties and durability of the carbon fiber-, glass fiber-reinforced MMA-matrix composites are presented. Finally, the challenges of the preparation and application of the MMA-matrix composites are identified.
