Identifying the fiber/matrix interphase of unidirectional composites (glass fiber/epoxy) with gradient in crosslink density by means of dynamic mechanicalthermal analysis (DMTA)
Identifying the fiber/matrix interphase of unidirectional composites (glass fiber/epoxy) with gradient in crosslink density by means of dynamic mechanicalthermal analysis (DMTA)
The fiber/matrix interphase was identified by comparing the tan delta spectra of resin and that of the composite with the Origin software. The results show that the interphase is hydrophilic and has an incomplete crosslinked network.
