Abstract - Our project motive is to increase the overall
industries due to its versatility and compatibility with existing manufacturing processes. However, it's important to note that PLA is not without its limitations. It can be more expensive to produce compared to traditional plastics, and it has certain limitations in terms of temperature resistance and durability Overall.
properties of by adding inorganic fillers such as copper oxide and PLA three specimen of different matrix were prepared by moulding process and it is subjected to examination to obtain their tensile strength, in addition to that, the microscopic analysis is operated to observe the fracture surface of specimen and the properties of the various specimen was compared and it is recorded
1.1.1 PROPERTIES OF POLYLACTIC ACID Polylactic acid (PLA) is a type of biodegradable polymer made from renewable resources, such as corn starch or sugarcane. Here are some key properties of polylactic acid:
Key Words: PLA and Copper Oxide.
1. INTRODUCTION The occurrence of fracture commonly occurs in our daily lives, for example, the dish breaks into several pieces when accidently dropped on the floor. In the package industry, the package of food can be opened by tearing. In case of fracture occurs, some of these instances are spontaneous and others are controlled by people and mostly due to the mechanism of the design. Metal and non-metal material is widely used in our common lives and especially polymer material has increased significantly in last fifty years. In this research, Polylactic acid (PLA) is mainly focused on. PLA is widely used in packaging industry. The food packaging industry, PLA is widely used and has been applied in Packaging for food and beverages for many years. Currently, PLA cover are installed more than the other plastic cover. In the last twenty years, PLA have also been used as a protection layer for cables in construction structure to prevent corrosion.
Biodegradability: PLA is known for its biodegradability, meaning it can be broken down by microorganisms in the environment, unlike traditional plastics.
Renewable Resource: PLA is derived from renewable resources, making it more sustainable than petroleumbased plastics.
Transparency: PLA has good transparency, making it suitable for transparent or translucent applications. • Strength and Rigidity: PLA has good tensile strength and rigidity, which makes it suitable for a wide range of applications
Temperature Sensitivity: PLA has a relatively low melting point, typically around 150-160 degrees Celsius, which should be considered when choosing PLA for hightemperature applications.
Limited Chemical Resistance: PLA is not resistant to most organic solvents and has limited resistance to moisture, so it may not be suitable for certain environments or applications.
Processability: PLA can be processed using various techniques, such as injection molding or 3D printing, making it versatile for different manufacturing processes.
It's important to note that specific properties of PLA can vary depending on the grade or formulation being used
1.1 INTRODUCTION ABOUT POLYLACTIC ACID Polylactic acid (PLA) is a type of biodegradable polymer that is derived from renewable resources such as cornstarch or sugarcane. It is a popular alternative to traditional plastics, which are derived from fossil fuels and have a significant negative impact on the environment. PLA is considered to be an environmentally friendly option because it is made from renewable resources and can break down into natural components over time. This means that it is less likely to contribute to the accumulation of plastic waste in landfills or oceans. In addition to its eco-friendliness, PLA also has a wide range of applications. It can be used to make packaging materials, disposable cutlery, food containers, and even 3D printing filaments. PLA has gained popularity in various
