초록

A three-dimensional spacer knitted fabric (3D fabric) consisting of ultra-high molecular weight polyethylene (UHMWPE) fibers and polyethylene terephthalate (PET) monofilaments (used for ground surfaces and pile yarn) with a ratio of 80% and 20% by volume, respectively, was produced in a Raschel machine with two needle bars. A 3D fiber-reinforced plastic (3D FRP), with cylindrical holes of 20 mm and 28 mm diameter was produced by the vacuum-assisted resin transfer molding (VaRTM) method, with a 3D fabric as a reinforcement and an unsaturated polyester resin as a matrix. Milled carbon fiber particles (CP), with a diameter of $100{\mu}m$, were added into the resin as sub-reinforcement. The mechanical properties of the obtained FRPs were investigated. The apparent space fraction of the prepared 3D FRP was estimated to be approximately 47.1% (which should be a light-weight structure) and the reinforcement-to-matrix weight ratio can reach approximately 60% or more. With regard to the tensile properties of the 3D FRP, tensile strength is higher in the wale of the fabric, while elongation is higher in the course. For 3D-CP/FRP produced with 0, 5, and 10 wt% in CP content, increasing the CP content in 3D FRP makes its decomposition temperature higher and increases its storage modulus to 10 times above the higher temperature range compared to glass transition. Flexural properties and abrasion resistance are improved as the CP content in FRPs increases.
