Manufacturing and Mechanical Characterization of Bio-Based Laminates and Sandwich Structures

Abstract

Jute fabric is well-known reinforcing material in composite science, however, there is a necessity to treat these fabrics to reduce moisture uptake and improve properties. Nevertheless, every modification increases the cost and reduces the possible applications. Presented research deals with an investigation of possibility to use untreated jute in various fabric weight as a reinforcing material in sandwich structures facings. Untreated jute reinforcements and two types of cork cores were saturated in one step during vacuum infusion creating a lightweight sandwich composite. All samples were mechanically tested in three-point bending test. Experimental results showed the most appropriate material combination and produced sandwich structure are proposed for design applications.

Review of literature on eco-friendly sandwich structures made of non-wood cellulose fibers

“…Hachemane et al [136] evaluated the impact response of cork core sandwiched by jute/epoxy face sheets. Karaduman [137] and Fojtl et al [138] investigated the dynamic/flexural characteristics of the renewable sandwich structures composed of cork cores covered by jute-reinforced composite face sheets.…”

“…[177][178][179][180] deal with the behaviors of kenaf-reinforced epoxy core sandwich panels in thermal stability, bending, compression, impact, and water absorption. Zainol Abidin et al [181] performed an experiment to analyze the ballistic impact response of sandwich structures with kenaf-reinforced PU Bending [123], [125], [126], [127], [128], [129], [132], [133], [135], [137], [138], [139], [142], [146], [147], [148], [149] [110] [ 150], [151], [154], [155], [156], [157], [159], [160] [161], [162], [163], [166] Compression [123], [128], [132], [134], [135], [141], [143], [148], [149] - [154], [157] [164], [165] Impact/ crashworthiness [124...…”
