Abstract

This study focuses on the development of a conventional oven using glass-fiber-reinforced thermoset composite sandwich panels. The design process considers the thermomechanical properties of the selected materials. The constructed rectangular box oven has the overall dimensions of 450 mm × 450 mm × 600 mm and internal heat chamber dimensions of 400 mm width, 400 mm depth, and 400 mm height with two stack trays for product placement. The sidewalls consist of inner and outer E-glass-fiber-reinforced composite panels with a sandwiched rockwool insulator. The bottom panel of the oven has an inner ceramic tile plate to suspend the electric heating element. The top panel is made of the same composite sandwich with a constructed superstructure electrical wiring compartment included for the controls. The oven can stably achieve a temperature of 150 ℃ and a cooking efficiency of approximately 39% when in operation and can sustain heat for more than 6 h standing time when turned off. The oven can be used for both culinary and laboratory experiments, i.e., heating, baking, drying, and curing materials, and is more affordable than alternative designs in the market.

Bahasa Abstract

Rancangan Ekonomis, Fabrikasi, dan Evaluasi Kinerja Oven-Oven Konvensional yang Dibuat dari Komposit-Komposit Termoset yang Diperkokoh dengan Serat Kaca. Kajian ini memfokuskan pada perkembangan suatu oven konvensional yang menggunakan panel-panel lapisan komposit termoset yang diperkokoh dengan serat kaca. Proses rancangan mempertimbangkan sifat-sifat termomekanis bahan-bahan yang dipilih. Oven kotak empat persegi panjang yang dibangun memiliki dimensi 450 mm × 450 mm × 600 mm dan dimensi ruang panas bagian dalam adalah lebar 400 mm, kedalaman 400 mm, dan tinggi 400 mm dengan dua tumpukan baki untuk penempatan produk. Dinding-dinding sisi terdiri atas panel-panel komposit dalam dan luar yang diperkokoh dengan serat kaca E dengan suatu isolator rockwool berlapis-lapis. Panel bawah oven memiliki suatu pelat ubin keramik dalam untuk menahan elemen pemanas listrik. Panel atas dibuat dari lapisan-lapisan komposit yang sama dengan suatu ruang kawat listrik yang dibangun dengan struktur super yang dimasukkan untuk pengendalian. Oven tersebut dapat mencapai suatu temperatur 150 ºC dengan stabil dan suatu efisiensi memasak mendekati 39% ketika beroperasi dan dapat menahan panas selama lebih dari 6 jam setelah oven dimatikan. Oven tersebut dapat digunakan baik untuk eksperimen kuliner maupun laboratorium, yaitu, memanaskan, memanggang, mengeringkan dan mengeraskan bahan-bahan, dan jauh lebih terjangkau dibandingkan dengan rancangan-rancangan alternatif yang ada di pasaran.
