Course abstract

Wood composites are derivatives of wood products. There are manufacturers that produce different types of wood composites. Depending on their application, the physico-mechanical properties of these wood composites, etc., must be known. characteristics. The study course examines the theoretical foundations of composites, production technologies and equipment to be used, as well as the technical and economic rationale for the use of new composite materials from the point of view of environmental protection during their production and use, as well as during their processing. The aim of the study course is to introduce students to wood composite materials, their properties and production technologies.

Learning outcomes and their assessment

Knowledge of advantages and disadvantages of wood composite materials (defense of laboratory work and oral assessment). Skills in creating the theoretical base of various wood-wood composites (defense of independent work, laboratory work and oral assessment). Competence to find the most suitable, environmentally friendly and economically advantageous variant of the development and execution of the imagined wood composite product (defense of independent work, laboratory works and oral assessment).
