Item Análisis de propiedades mecánicas a utensilios biodegradables(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2025-02) Araujo Pérez, Kevin Ricardo; Reinoso Manobanda, Marlon Joel; López Velástegui, Jorge EnriqueThis analysis aims to evaluate the mechanical properties of biodegradable spoons and forks to determine their viability as a sustainable alternative to conventional utensils. The development of prototypes from biodegradable materials allows competition in relation to plastic products due to their high contamination worldwide. Mechanical parameters were analyzed to determine whether the material used in the fork and spoon prototypes are efficient and comparable to plastic utensils. These mechanical parameters include bending, tensile, hardness and hydrophobicity, the first three parameters are performed on a universal mechanical testing machine, while the last one is performed in a conventional way with a design program, where the contact angle was measured. The materials used for the fork and spoon prototypes are a key element to achieve similar properties to plastic and biodegradable utensils already on the market, so corn starch and wheat starch were chosen. The analysis of these parameters was compared qualitatively and quantitatively. The results obtained showed that the utensils made from wheat starch have similar characteristics, being in some aspects superior to plastic and biodegradable utensils on the market. In addition, their hydrophobic behaviour was optimal, as the contact angle exceeded 90 degrees at most points, making them a viable alternative for the biodegradable utensil industry.
