1. An Alternative Test Method For Characterizing Wet Out And Internal Integrity Of Pultruded Shapes
Pultrusion is a continuous, fiber reinforced plastic (FRP) manufacturing process which produces highly reinforced cross sections. These cross sections are usually constant in nature, which helps facilitate the continuity of the operation. This proces ...
2. Color Instrumentation: The Measurement And Communication Of Color
There are several types and designs of instruments currently available for measuring and communicating the color differences of finished products. Some popular spectrophotometer designs are the 45/0 geometry, 0/45 geometry, and the diffuse/8 integrat ...
3. Cone Calorimeter As A Screening Test For ASTM E-84 Tunnel Test
The commercial and architectural building industries use the ASTM E-84 (Steiner Tunnel) test to set the standards for fire retardant materials. In developing new products to meet the building codes that are based on ASTM E-84 test results, a large am ...
4. The Influence Of Cure Systems On The Formation Of Volatile Components In RTM Processed UP Articles
Resin transfer moulded (RTM) parts containing LP and LS additives have been found to contain high volatile components and these are present or formed both during the process and storage. In this article two major volatiles namely monomeric styrene an ...
5. Evaluating Ceramic Compounded Resins As Surface Barriers In FRP Parts
Over the past several years ceramic compounded resins have been introduced in to fiberglass/polyester laminates as barrier coats to produce a superior surface finish and to prevent fiber print through and air pocket break out. Although this material ...
6. Experimental Examination Of Filament Winding With BAPO Photoinitiated Resins
When a photoinitiator is added to a styrene/unsaturated polyester or a vinyl ester resin in place of peroxide, light can be used as the energy source for cure of polymeric composites. Photoinitiated resins are thermally stable and offer numerous pot ...
7. Importance Of Compressive Wedge Testing For Secondary Bonding In Laminates
This paper investigates a new method of evaluating secondary bonding between several layers of a laminate using compressive wedge testing. This method is accurate, easy to perform and answers the questions: “Will my laminate maintain its int ...
8. Quantification Of The Internal Structure Of Continuous Fiber Composites Through Large Area Automated Microscopy
We describe the use of Large Area Automated Microscopy (LAAM) for the topological characterization of entire cross-sections of pultruded carbon fiber reinforced rods. This characterization is an essential step in developing currently unavailable quan ...
9. Strength Retention Of Pultruded Composites After Exposure To Ultra-Violet (UV) Light
A study was undertaken to determine the effects on the physical properties of pultruded profiles when exposed to accelerated ultraviolet light and Florida outdoor tests. The laboratory work demonstrates that even if the surface area shows sign of ult ...
10. A Study Of The Integrity Of The Transition Region Of Variable Cross-Section Thermoset Pultrusions Produced Via Selective Interval Pulshaping
Several recent papers have described a new automated manufacturing technique called Selective Interval Pulshaping for production of useful articles via a hybrid pultrusion/compression molding process. The patented method is unique in that it relies e ...
