Abstract
The paper proposes composite materials for the manufacturing of parts of the car body structure, namely a door. This work aims to analyze the possibility of replacing the metal door of a vehicle with a door made of composite materials. Specific issues related to this replacement are analyzed in the paper. Test specimens were made of composite materials of different sizes, using several types of constituents to determine which material might be most suitable to replace metal in the manufacturing of the door. The choice of materials for the car door was made starting from the characteristics of the analyzed composite materials, but also taking into account the manufacturing possibilities and other engineering limitations. The behavior of the automotive structure as analyzed, using the finite element method for determining the stresses in the structure. Experimental verifications were performed on an experimental stand which has been specially designed for this purpose, to validate the proposed model.
Highlights
The replacement of metal materials used so far in the automotive industry with plastics and composites has led to increased service life, increased noise and vibration absorption, and intercompartmental insulation of vehicles to absorb the kinetic energy of shocks in the case of accidents in an environmentally friendly way
The technology of obtaining these components has an important role in choosing the material used to make the car parts
The composite material made of fiberglass supports a considerable load if it is in normal temperature conditions and if it does not contain materials that can damage its homogeneous structure
Summary
The materials used to reinforce the plates are fibe carbon fiber From these plates the specimens necessary for the tests on the stan to establish the characteristics of the composite materials studied. The behavior of the automotive structure m carbon fiber From these plates the specimens necessary for the tests on the stand were chosen materials was analyzed, the finiteThe element method for cut tocomposite establish the characteristics of the composite using materials studied. The following five types of materials were studied: The first class of composite test specimens are made of polyester resin, reinforced a specific mass of. The fifth material tested was made of epoxy resin, reinforced with five layers of carbon elasticity, flexural and strain and the material flexural stress–strain fiber fabrics and onestress, layer of polyester These specimens suffered total ruptures, only realize the testdetachments is a three-point fixture.
