Abstract

UV-curable photopolymer resins are widely used for decorative coatings and additive manufacturing due to their solvent-free, rapid curing. This study investigates the valorization of chestnut shell waste (CSW) as a sustainable lignocellulosic filler in a plant-based UV resin for non-load-bearing applications. Composite specimens with 1, 5, and 10wt.% CSW were prepared and cured at 405 nm for 10 minutes. Tensile and water absorption tests revealed that increasing CSW content reduced tensile strength and elongation due to particle agglomeration and limited UV penetration. Higher filler loading also increased water absorption because of the hydrophilic nature of the lignocellulose. Results indicate that 0–5wt.% CSW provides an optimal balance of mechanical integrity and moisture resistance for sustainable engineering products.

Özet

UV ile kürlenebilen fotopolimer reçineler, çözücü içermemeleri ve hızlı kürlenme özellikleri nedeniyle dekoratif kaplamalar ve eklemeli imalat süreçlerinde yaygın olarak kullanılmaktadır. Bu çalışma, bitki bazlı bir UV reçinesi içinde sürdürülebilir bir lignoselülozik dolgu maddesi olarak kestane kabuğu atığının (CSW) yük taşımayan uygulamalar için kullanımını incelemektedir. %1, %5 ve %10 ağırlık oranlarında CSW içeren kompozit numuneler hazırlanmış ve 405 nm dalga boyunda 10 dakika süreyle kürlenmiştir. Çekme ve su emme testleri, artan CSW içeriğinin parçacık aglomerasyonu ve sınırlı UV nüfuziyeti nedeniyle çekme mukavemetini ve kopma uzamasını azalttığını ortaya koymuştur. Ayrıca, lignoselülozun hidrofilik doğası nedeniyle yüksek dolgu oranlarında su emme kapasitesi artmıştır. Sonuçlar, %0-5 ağırlık oranındaki CSW kullanımının, sürdürülebilir mühendislik ürünleri için mekanik bütünlük ve nem direnci arasında optimal bir denge sağladığını göstermektedir.
