Analysis of hydrolysis process of g-methacryloxypropyltrimethoxysilane and its influence on the formation of silane coatings on 6063 aluminum alloy
Pantoja Ruiz, Mariola; Díaz Benito, Belén; Velasco López, Francisco Javier; Abenojar Buendía, Juana; del Real Romero, Juan Carlos (01/04/2009)In this paper the hydrolysis process of ?-methacryloxypropyltrimethoxysilane (MPS) at 1% in an aqueous solution by means of Fourier transform infrared (FTIR) spectroscopy was studied. The aim of this work is to determine ... -
Analytical solution to calculate the stress distribution in pin-and-collar samples bonded with anaerobic adhesives (following ISO 10123 standard)
Martínez Casanova, Miguel Ángel; Velasco López, Francisco Javier; Abenojar Buendía, Juana; Pantoja Ruiz, Mariola; del Real Romero, Juan Carlos (01/12/2008)In this work, we analyse cylindrical joints bonded with anaerobic adhesives, applying the principles found in a paper of Nemes et al. [Int J Adhes Adhes 2006; 26(6) :474]. Nemes paper gives an analytical solution for the ... -
Effect of moisture and temperature on the mechanical properties of an epoxy reinforced with boron carbide
Abenojar Buendía, Juana; Martínez Casanova, Miguel Ángel; Velasco López, Francisco Javier; del Real Romero, Juan Carlos (01/08/2011)The degree of degradation in a polymer composite is directly related to the amount of moisture it absorbs. Plasticization and swelling are among the undesirable consequences of absorbed water. This effect is rather important ... -
Environmental evaluation of silanes as adhesion promoters for organic coatings
Cledera Castro, María del Mar; Ballesteros Iglesias, María Yolanda; Pantoja Ruiz, Mariola; Velasco López, Francisco Javier (01/07/2012)In the literature of silane treatment there are not many studies about the deterioration of baths of silane and the possible treatments that could be used to reduce their polluting effects. The purpose of this paper is to ... -
Epoxy composite reinforced with nano and micro SiC particles: curing kinetics and mechanical properties
Abenojar Buendía, Juana; Martínez Casanova, Miguel Ángel; Pantoja Ruiz, Mariola; Velasco López, Francisco Javier; del Real Romero, Juan Carlos (01/05/2012)Epoxy-based composite materials reinforced with hard particles can be used as anti-wear coatings. In this study, a commercial bicomponent resin was used, with 6 and 12% SiC particles in two different particle sizes (nano ... -
Fiabilidad de los adhesivos anaeróbicos como fijadores y retenedores de pasadores y roscas
Pantoja Molina, Miguel Ángel; Velasco López, Francisco Javier; Abenojar Buendía, Juana; Martínez Baena, Manuel Antonio; Durban, M.; del Real Romero, Juan Carlos (01/08/2007)En los montajes por desplazamiento de pasadores, en uniones roscadas, o en sellado de piezas, son muy utilizados los adhesivos anaeróbicos. Para comprobar las características de la unión que producen esta muy extendido el ... -
Influence of thread geometry on the performance of retaining anaerobic adhesives
Martínez Casanova, Miguel Ángel; Pantoja Ruiz, Mariola; Abenojar Buendía, Juana; del Real Romero, Juan Carlos; Velasco López, Francisco Javier (01/09/2011)The main aim of this work is to study the influence of the geometry of screws on torsion tests when they are retained with adhesives. The geometry of different types of screw threads has been studied, measuring theoretical ... -
