“…In order to address this issue, humanity has begun to develop eco-friendly composite materials made from recycled materials [3]- [7]. Among these materials, the most important ones that can be used as substitutes for wood are particle board (PB), medium-density board (MDF), plywood, wood sandwich panels, and wood-plastic composites [8]- [12].…”

In this study, polystyrene (PS) has been melted using gasoline and used as an adhesive in Plywood production. Nowadays, thermoset resins which have formaldehyde emission are used in Plywood production. This study aims to enable the recycling of waste polystyrene and produce eco-friendly Plywood. Beech veneer (BC) with a thickness of 2 mm is used as the wood material. On top of the BC, PS sheets with the same width and length dimensions, but with a thickness of 5 mm, were placed. Then, gasoline was sprayed onto the PS sheets. In this way, 6 layers of BC and 5 layers of PS plates were overlapped together and cold-pressed under 4 bar pressure for 24 hours without using any heat during the process. Similarly, 3 pieces of 3 mm Medium Density Board (MDF) and 10 mm PS plate (20 kg/m 3 ) were overlapped each other and then cold-pressed. MDFs bonded with polyurethane (PU) and polyvinyl acetate (PVA) were also prepared in 3 layers. Afterward, analysis samples were cut from these materials. Mechanical and physical characterization of the samples was conducted according to TSE (Turkish Standards Institution) standards, including bending, tensile, screw holding, density, water absorption, and thickness swelling analyses. According to results, it has been determined that the sample produced with PU has the highest mechanical strength and physical durability. The samples produced using melted PS exhibit mechanical strength and physical resistance above the standards. As a result of the study, it is concluded that waste PS, after being melted with gasoline, can be used as an adhesive in plywood production. Thus, eco-friendly plywood without formaldehyde emissions can be manufactured.

The objective of the present study is to reveal the toughening effect of the hazelnut shell on the brittle matrices by using the bending and breaking methods. The polymethylmethacrylate composites reinforced with hazelnut shell powder with 50µ particle size at the weight concentrations of 5%, 10%, 15%, and 20% were prepared. The polymer beam samples were exposed to heat cure procedure and the initial notches were created at a/W=0.1, 0.2, 0.3, 0.4, and 0.5. The Mode I breaking behaviors of the notched at single edge and non-notched composite samples were examined by using three-point bending test. The critical stress intensity factor (KIC), J-integral, initial notch depth, and compliance methods were used in calculations. Besides them, the bending module and bending stress values were calculated. The microstructures of HNSP/PMMA composites were determined by using XRD (x-ray diffractometer), FTIR (Fouirer Transform Infrared Spektrofotometre), and SEM (scanning electron microscope) analyses. According to the results obtained, it was determined that the bending strength, elasticity module, and fracture toughness values increased at 10% additive ratio for the HNSP (hasel nut shell flour)/PMMA (polymethylmethacrylate) composites. Özet Çalışmanın amacı, gevrek matrislerde fındıkkabuğunun toklaştırma etkisini eğilme ve farklı kırılma yöntemleri ile ortaya koymaktır. 50µ partikül boyutuna sahip %5, %10, %15 ve %20 ağırlık oranlarında fındıkkabuğu tozu takviyeli /Polimetilmetakrilat kompozitler üretildi. Üretilen polimer kiriş numunelere, ısıl kür işleminden sonra, a/W= 0,1, 02, 03, 04, 0,5 başlangıç çentikleri açıldı. Çentiksiz ve tek kenardan çentik açılmış kompozit numunelerin mode I kırılma davranışları üç nokta eğme testi uygulanarak ortaya konuldu. Kritik Gerilme Şiddet Faktörü (KIC) J-integral, Başlangıç Çentik Derinliği ve Komplians metotları ile hesaplandı. Bununla birlikte eğilme modülü ve eğilme gerilmeleri de belirlendi. HNSF/ PMMA kompozitlerin mikro yapısı XRD, FTIR ve SEM çalışmaları ile ortaya konuldu. Çalışmanın sonuçlarına göre, fındıkkabuğu tozu / Pmma kompozitlere eklenen tozların %10 katkı oranında eğilme kuvveti, eğilme modülü ve kırılma tokluğunu arttırdığı belirlenmiştir.
