Traditional boats have been using wood as raw material for their construction, due to lacking of wood, an alternative wood substitutes must be found. Plywood is known as a material made from a sheet of wood veneer glued together with a perpendicular cross-sectional arrangement and is used widely. The mechanical and physical properties of plywood do not meet the physical and mechanical requirements for use as boat building materials, so that the sandwich process with glass fiber polyester has been proven to improve the physical and mechanical properties for boat materials. Plywood material with a thickness of 6 mm that is strengthened by sandwich on both surfaces using 1 layer of glass fiber polyester (roving) obtained bending strength reaches 87 MPa so that it meets the requirements to be used as material in the manufacture of fishing boats referring to SNI 01-7211-2006. The main objective is to carry out the spread of Science and Technology about the manufacture of fishing boats from plywood materials coated with glass fiber polymer composites. In order to teach the public about composite coating technology so that the dominance of wood as a boat material can be replaced by plywood that can be obtained easily on the market. This activity has successfully implemented the application of appropriate technology: Knowledge of Resins, glass fibers and the benefits of using Polyester Fibers reinforced with fiberglass. Furthermore, the making of a boat frame from plywood and the practice of the process of making a glass fiber polyester composite layer on the surface of the boat. The success rate of conducting training activities in making plywood boats to the Lapang Barat village community reached a range of 82% based on the ability to make a proper mixture between resin and hardener, cutting and handling glass fiber and attaching it to the surface of the boat, pouring and smearing the resin and leveling it ended with storage capability resin to remain intact

Recently the critical discussion about the preservation of natural resources and recycling has led to the renewed interest concerning biomaterials with the focus on renewable raw materials. Because of increasing environmental consciousness and demands of legislative authorities, use and removal of traditional composite structures, usually made of glass, carbon or aramid fibers being reinforced with epoxy, unsaturated polyester, or phenolics, are considered critically. Recent advances in natural fiber development, genetic engineering and composite science offer significant opportunities for improved materials

Abstract The academic and industrial aspects of the preparation, characterization, mechanical and materials properties, crystallization behavior, melt rheology, and foam processing of pure polylactide (PLA) and PLA/layered silicate nanocomposites are described in this feature article. Recently, these materials have attracted considerable interest in polymer science research. PLA is linear aliphatic thermoplastic polyester and is made from agricultural products. Hectorite and montmorillonite are among the most commonly used smectite‐type layered silicates for the preparation of nanocomposites. Smectites are a valuable mineral

Abstract Plastic composites are members of both the oldest and the newest of materials. The first reinforced polymeric-based materials are recorded in Genesis and Exodus in the Bible as being used by the people of Babylonia and Mesopotamia around 4000–2000 B.C. These materials consisted of bitumen-based pitch for building products and bundles of papyrus reed embedded in a bitumen matrix for the construction of river boats [1]. The Hindu Vedas (written about 1000 B.C.) refers to the use of lac
