A Math-Based Methodology for Fatigue Longevity Prediction of 3D Woven Fiberglass Reinforced Vinyl-ester Composites (.pdf)
In the DOE-Delphi Composite Chassis Cross-Member program, 3TEX 3Weave (3D woven fiberglass mat)/vinyl-ester (Dion 9800) composites have been investigated as a candidate material. One of the most important mechanical properties for qualifying these composites for such applications is the mechanical

An Investigation of Pin Bearing Strength on Composite Materials (.pdf)
that the. ASTM D 953 bearing strength test can be very misleading and that actual connection details. should be mimicked in order to generate sound design values. Introduction. The design of connections, within Fiberglass Reinforced Polymer (FRP) structures, is one of the. most critical elements when

Laser Machining Fiber-Reinforced Plastics
, light and very expensive composite material or fiber reinforced plastic. Similar to glass-reinforced plastic, which is sometimes simply called fiberglass. The composite material is commonly referred to by the name of its reinforcing fibers. Some FRPs' contain both carbon fiber and fiberglass

Lighting Strike Test Results
As the application of composite aero structures has increased, the effect of lightning strike damage and the structural tolerance necessary to absorb this damage has required further test investigation. To enhance the damage tolerance capability of composite sandwich structures used for commercial

What new analysts should know about composites
Recent additions to FEA software make it easier to find stresses and strains in composites. Composites of fiberglass have been around for almost 70 years. Carbon fibers came along about 20 years ago and promised even lighter and stronger composites. The only drawback was accurately predicting

Lube-for-life journal bearings
on a sintered structure but the lubricant is embedded in the reinforcing matrix. Such bearings have fairly limited life and are typically found in applications that can accommodate significant bearing wear. Composite bearings from Polygon Co., Walkerton, Ind., combine a high-load continuous-fiberglass-filament

The "no-cog" motor
design for an air-bearing application in a servo writer. The coil in this cutaway of a ThinGap motor is made from precision-milled sheet copper in a fiberglass and polyimide material composite, rather than from conventional copper wires. The magnetic path for the permanent magnets is shortened

The Making Of Bullet Resistant Products
at 10:53 am by Protective Structures. In order to improve safety, various materials have been developed and incorporated in various applications. One of the greatest materials that have been developed by man is composite materials. These materials are actually a combination of two or more material
