[0090] experiment method

[0091] Gas chromatography (GC) procedure Gas chromatography was performed using a gas chromatograph commercially available under the trade name "AGILENT 6890N" equipped with a HP7683 injector and a HP-5 column ((5% phenyl-methylpolysiloxane alkane), 30 meters in length and 320 microns in internal diameter (obtained from Agilent Technologies, Incorporated, Santa Clara, California, Agilent Technologies, Incorporated, Santa Clara, California). The following parameters were used: Inject 10% of the sample 1 microliter aliquot of the solution (solvent is GC grade acetone); split inlet mode set to 250 °C, 65.6 kPa (9.52 psi) and a total flow rate of 111 mL / min; column constant pressure mode set to 65.6 kPa ( 9.52psi); the speed is set at 34 cm / s; the gas flow is 2.1mL / min; the detector temperature and the inlet temperature are 250°C; The temperature was raised to 260°C at a ramp rate of 20°C / min.

example 1

[0096] Example 1 (EX-1) A fiber composite comprising a resin system containing surface-modified silica nanoparticles was prepared as follows. By adding 0.73 parts by weight of NALCO2327 silica (41.1 wt% silica in aqueous dispersion, obtained from Nalco Chemicals, Naperville, Illinois, lot BP9J1622A4) Surface-modified silica (SMS) nanoparticles were prepared by adding to the jar along a magnetic stir bar. Place the jar on a stir plate and stir the solution creating a 2 cm to 5 cm vortex. Then 1.00 parts by weight methoxypropanol was mixed with 0.03674 parts by weight trimethoxyphenylsilane (Gelest Inc., Morrisville, Pennsylvania, Lot 1B-15944). The resulting methoxypropanol mixture was slowly poured into a jar containing the silica while stirring the mixture with a magnetic stir bar. The jar was sealed and placed in a batch heat treatment furnace at 80°C for 16 hours. The resulting sample designated "SMS-1" contained 16.9% by weight silica.

[0105] Example 2 (EX-2) A fiber composite comprising a resin system containing surface-modified calcite nanoparticles was prepared as follows. First, 18,015 grams of calcite (SOCAL31); 9,608 grams of epoxy resin (EPON828); 2,402 grams of diglycidyl ether of cyclohexanedimethanol (HELOXY107); 1,352 grams of JAS ligand; and 5,500 grams of methyl ethyl ketone (MEK) were used A disperser equipped with f-blades (BYK-Gardner, Columbia, MD, USA) was premixed. JAS is preheated to 90°C to reduce its viscosity for easier handling.

[0107]

[0108] The JAS ligand can be prepared as described for Ligand V in International Patent Application PCT / US2009 / 068359 ("Nanocalcite Composites", filed December 17, 2009).

[0109]The premix was then passed through an LME-4 horizontal mill (NETZCH Fine Particle Technology, Exton, PA, USA) equipped with a stainless steel chamber and agitator (configured using Mollinex). material for grinding. 1-Metho...

Abstract

Pressure vessels formed from fiber composites are described. The fiber composites include fibers impregnated with a resin system containing surface-modified nanoparticles dispersed in a curable matrix resin.

Description

[0001] Cross references to related patent applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 355,769, filed June 17, 2010, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to pressure vessels, such as pipes and tanks, made using fiber composite materials. In particular, the present invention relates to pressure vessels formed from fibrous composites comprising fibers impregnated with a resin system comprising surface-modified nanoparticles dispersed in a matrix resin. Background technique [0004] Generally speaking, a pressure vessel is a structure capable of containing fluids (such as liquids, liquefied gases, compressed gases, and combinations thereof) under pressure. Exemplary pressure vessels include storage vessels such as fuel tanks, portable gas (such as oxygen) storage cylinders, and collectors, as well as pipes and conduits that can b...
