Cam Elyafı ve Karbon Elyafı İçeriğinin UV ile Kürlenmiş Kompozitlerin Çekme ve Su Emme Davranışı Üzerindeki Etkileri

Öz

Gelişmiş polimer kompozitler, çok düşük ağırlıkları ve yüksek mekanik özellikleri nedeniyle otomotiv, havacılık ve denizcilik endüstrilerinde giderek daha sık kullanılmaktadır. Bu çalışmada, UV ile kürlenebilen bir reçineye ağırlıkça %1, %5 ve %10 oranlarında cam elyafı (GF) ve karbon elyafı (CF) ilavesinin kompozit malzemenin mekanik özellikleri ve nem direnci üzerindeki etkisi araştırılmıştır. Çekme özellikleri ASTM D638 Tip IV numuneler kullanılarak değerlendirilmiş, su emme karakteristikleri ise ASTM D570-98 standardına göre 28 günlük daldırma süresi boyunca belirlenmiştir. Saf reçine 6,1 MPa çekme dayanımı (UTS) ve %3,6 su emme değeri göstermiştir. %10 GF ilavesiyle UTS değeri 14,3 MPa yükselirken, %10 CF ilavesiyle 19,3 MPa ulaşmıştır. GF takviyeli kompozitler, CF takviyeli kompozitlere kıyasla daha yüksek su emme eğilimi göstermiştir. GF takviyeli kompozitlerde su emme oranı %2,4–%3,2 aralığında değişirken, CF takviyeli kompozitlerde bu değer %2,3–%2,8 aralığında belirlenmiştir. Genel olarak, CF ilavesinin UV ile kürlenebilir reçine sisteminin hem dayanımını hem de su emmeye karşı direncini önemli ölçüde iyileştirdiği ve bu nedenle neme maruz kalan hafif yapısal parçalar için umut verici bir seçenek olduğu ortaya konmuştur.

EFFECTS OF GLASS FIBER AND CARBON FIBER CONTENT ON TENSILE AND WATER ABSORPTION BEHAVIOR OF UV- CURED COMPOSITES

Öz

Advanced polymer composites are used with increasing frequency in automotive, aerospace and marine industries, due to their very low weights and high levels of mechanical properties. This work investigates the effect of adding 1 %, 5 % and 10 wt.% glass fibers (GF), and carbon fibers (CF) to a UV curable resin, to determine how the addition of these fibers affects the mechanical properties and moisture resistance of the composite material. Tensile properties were evaluated using ASTM D638 Type IV specimens, while water absorption characteristics were determined according to ASTM D570-98 over a 28-day immersion period. The neat resin exhibited an ultimate tensile strength (UTS) of 6.1 MPa with a water absorption of 3.6 %. Incorporating 10 wt.% GF resulted in a UTS of 14.3 MPa, while incorporating 10 wt.% CF resulted in a UTS of 19.3 MPa. GF-reinforced composites showed higher water absorption than CF-reinforced composites. However, the absorption levels of GF-reinforced composites ranged from 2.4 % to 3.2 %, while those of CF-reinforced composites ranged from 2.3-2.8 %. Overall, this study showed adding CF greatly improved both the strength and water-absorption resistance of the UV-curable resin system, making it a promising choice for lightweight parts exposed to moisture.
