Currently there are many applications for the use of composites reinforced with fiberglass mat and fabrics polyester resin: automotive, aerospace, construction wind turbines blades, sanitary ware, furniture, etc. The structures made have a complex geometry, can be simultaneously subjected to tensile–compression, shear, bending torsion. In this paper we analyzed mechanical properties composite material glass fiber (denoted GFRP) which were carried out two types samples: former contains four...
The paper deals with the mechanical behaviour of natural fibre composites subjected to tensile test and dynamic analysis (DMA). Three types were prepared tested: wood particle reinforced six different sizes grains (WPC); hemp mat (HMP) flax composite mixed particles (FWPC). performed on universal testing machine LS100 Lloyd's Instrument highlights elastic properties samples, as longitudinal elasticity modulus; rupture; strain at break; stiffness. large dispersion stress-strain curves was...
In the acoustics of musical instruments with a resonator body, aging wood leads to improvement acoustic properties due increasing crystallinity wood. This phenomenon could be explained by fact that is complex product based on three-dimensional polymer chains carbohydrates, its being closely related covalent cross-linking and scission chains. The aim this study was evaluate at multiscale changes produced artificial tone measuring acoustic, mechanical chemical parameters. spruce maple samples...
The mechanical properties of wood, respectively the elastic, plastic, and strength properties, depend on a large number factors, due both to its structural physical characteristics, as well size, direction, nature, speed application forces. Wood, generally considered be viscous-elastic material, has creep deformations over time under effect constant load. In this study behavior pine wood samples was investigated utilization in different finished products, such roof construction, furniture,...
Composite structures are used mainly two types of reinforcement materials: woven glass fabric and the chopped strand mat, each contributing either to increase resistance composite whole or in isotropic distribution stresses. This paper presents a comparison visco-elastic characteristics composites reinforced with mat breaking mode composite. The first type samples contain three layers known as MAT density 450g/m2 225g/m2) second is composed four RT500 (density 500g/m2). Both specimens were...
In pipes made of HDPE used in city water supply networks, a specific type failure is commonly noted, called the parrot’s beak failure. It requires expensive intervention. The prediction and study development this defect, therefore, thorough research. work, finite element method to mechanism occurrence defect. Two examples calculation for concrete case some tubes network are presented. This important designers such predict prevent defect that can lead unwanted downtime high repair costs.
Paper explores the influence of infill density (%), as a process parameter in additive manufacturing (3D printing), upon mechanical (tensile, impact) and thermo-physical properties PLA samples. The results indicated degradation both tensile strengths moduli with decrease samples� relative from 100% to 25% 49.9% 42.0%, respectively. Similar behaviour holds on impact strength values that degrades 56.0% for samples printed using density. Young�s modulus variation was approximated 3rd order...
