Abstract:
Fiber-reinforced polymer composites (FRPCs) have been widely used as alternatives for metallic materials in aerospace, defense, transportation, and automotive industries because of their lower weight, higher strength, and stiffness. The use of ultrathin fibers (eg. electrospun nanofibers) of high surface area leads to improvement in the mechanical property of FRPCs associated with the interfacial bonding between nanofibers and polymeric matrices, enhancing the load transfer from the fiber to the matrix.
The micrometer-size porous polystyrene (PS) fibers obtained from electrospinning PS/THF solution with the nano-sized (100 to 200 nm) surface porosities were used to fill an epoxy matrix. The effect of incorporation of the PS fibers on the quasi-static and dynamic compression behavior of an epoxy matrix was examined. The addition of PS fibers and increasing strain rate increased the compressive elastic modulus and strength, which was attributed to the interlocking between the resin and fibers by the intrusions of the resin into surface pores on the fibers.
In addition, high strain rate deformation experimental data on porous PS fiber-reinforced epoxy matrix was provided. The excessive deformation of the matrix at the interface caused extra energy expenditure to deform the composite.
