Wettability of nano-epoxies to UHMWPE fibers

Nanocomposite coatings for healing surface defects of glass fibers and improving interfacial adhesion

“…One recent proposal is that the functionalized carbon material (e.g. CNT or nanocarbon fiber) within the coating is reactive with the reinforcement as well as the matrix material [32,33]. Besides, the coating with clay results in a much less degradation due to limited access of the aggressive alkali solution, which consequently increase the frictional component of bond.…”

The effect of graphene oxide (GO) nanoparticles on the processing of epoxy/glass fiber composites using resin infusion

“…It is also a common approach to break up GO agglomeration in order to achieve good GO dispersion in polymer matrices [20,21]. Nanomodified epoxy resins have shown great potential for the applications in fiberreinforced plastic (FRP) composites as matrices for resin infusion (RI) technology [22,23].…”

Cosmic radiation shielding tests for UHMWPE fiber/nano-epoxy composites

“…The previous research indicated that such nano-matrices with covalent bond between the nanofibers and polymer resins had greatly enhanced thermal and mechanical properties by synthesis of super molecular structures containing nanofibers, including the proposed strengthening mechanism [17][18][19][20][21][22][23][24][25][26]. The results on the nano-matrices showed that the nano-epoxy has very low nanofiber concentration (0.3 wt%) and interestingly, it showed lower surface energy and viscosity over the pure epoxy [21].…”

“…The nanoscale GNFs with controlled lengths, as the polymer resin molecule's side groups, could enhance mechanical properties drastically for the polymer matrices. In addition, fabrication of reactive nano-modified polymer resin can result in improved interfacial adhesion with the conventional fibers in the macro composites [14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Moreover, the reactive functional group led to the formation of a special interface with good adhesion, enhancing the properties of the resulting composites [14][15][16][17][18]. Although the matrix cannot form chemical binding with UHMWPE fibers, this reactive nano-matrix led to good wetting and adhesion to the UHMWPE fiber surface [21,22,24]. For developing high properties of nano-epoxy, we have developed solutions to the key problems including (1) strong interaction between graphitic nanofibers and epoxy resin through further treatment to achieve covalent bonding level; (2) uniform dispersion of the graphitic nanofibers in a polymer; and (3) curing mechanism for optimization of cure cycles [15,16].…”
