Rubber is a polymer that is classified into two types, namely, natural rubber and synthetic rubber. Natural rubber is extracted from latex, which is a milky fluid emanating from the bark of rubber trees, while synthetic rubber is manufactured through chemical processes. The rubber is processed using various chemicals to improve its resistance to heat, sunlight, oxidation, ozone, and mechanical stress. Rubber processing chemicals are also an integral component used for vulcanizing rubber. They are classified into different groups based on their functions. The different types that are mainly used are antidegradants, accelerators, processing aids, anti-scorch agents, blowing agents, polymerization regulators, and shortstops.

Lyocell is a manufactured fiber that is derived from cellulose. Lyocell fiber is manufactured through a solvent spinning technique by the closed loop method, where cellulose experiences a chemical change. Lyocell fibers are widely used in textiles. Although lyocell is manufactured it is a natural fiber because it is made from wood pulp. Lyocell fiber is the strongest cellulose fiber when dry and known for its property of durability.

Specialty pressure-sensitive tapes adhere to surfaces when pressure is applied and do not require solvents, heat, or other agents. These tapes are used in industrial and construction applications because of their high-tensile strength. They are also used in the healthcare and automotive industries for their fastening and bonding properties. Many variants of these tapes, such as double-sided tapes, are available in the market.

The handbags market in Europe is growing at a steady rate. This is expected to continue during the forecast period. Demand for handbags, including shoulder bags, totes, crossbody, clutches, wallets, satchels, and sling bags is on the rise. Numerous brands offer a wide range of products in different price ranges through retail stores and online retail channels. Some of the leading brands are Louis Vuitton, Fendi, Miu Miu, Prada, Mulberry, Chanel, Christian Dior, and Gucci.

A micromechanics analysis modeling method was developed to analyze the damage progression and fatigue failure of fabric reinforced composite structures, especially for the brittle ceramic matrix material composites. A repeating unit cell concept of fabric reinforced composites was used to represent the global composite structure. The thermal and mechanical properties of the repeating unit cell were considered as the same as those of the global composite structure. The three-phase micromechanics, the shear-lag, and the continuum fracture mechanics models were integrated with a statistical model in the repeating unit cell to predict the progressive damages and fatigue life of the composite structures. The global structure failure was defined as the loss of loading capability of the repeating unit cell, which depends on the stiffness reduction due to material slice failures and nonlinear material properties in the repeating unit cell. The present methodology is demonstrated with the analysis results evaluated through the experimental test performed with carbon fiber reinforced silicon carbide matrix plain weave composite specimens.
