1.  A Comparison Of UV Lamp Sources For Curing Fiberglass Composites

Open mold fiberglass composites are currently cured via a catalyst at room temperature or sometimes in ovens over long periods of time, typically an hour or so for each layer. A finished boat hull, for example, may have as much as five hours of cure ...

2.  Infusion Cosmetics: Understanding Materials Contribution To Cosmetics

The single most important feature of composite articles is the ability to produce them in complex and beautiful shapes. Manufacturers have been able to design and produce composite articles which could not have been made in any other way. The emphasi ...

3.  Joining Methods For Honeycomb And Sandwich Structures

This discussion provides design information for joining sandwich composite structures with a focus on honeycomb sandwich panel applications. While there are several types of core materials to choose from, such as closed cell foam and balsa wood, hone ...

4.  The Relationship Of Unsaturated Polyester Resin Cure Parameters To Laminate Surface Profile

Presented is an examination of the surface profile of panels constructed with a typical gel coat backed with a fiberglass reinforced polyester resin laminate ranging from 2 mm to 7mm thick. The resin used to manufacture the laminates is a dicyclopent ...

5.  Using Temperature To Stabilize Dispensing Processes: Applying Lessons Learned By The Automotive Manufacturers To The Composites Industry

The flood of advanced materials developed over the last 20 years has created changes in virtually all of the products that we see and use every day. Nowhere is this more apparent than in the automotive industry. What started with bolted and welded st ...

6.  Effect Of Die Length On Pulling Force And Composite Quality In Pultrusion

Development of high-speed pultrusion technology requires a thorough understanding of the process. The objectives of this study are (1) to understand the effect of die shape, die length, and pulling speed on pulling force and resin cure, and (2) to st ...

7.  Experimental Examination Of The Effects Of Internal Mold Release Agents For Pultrusion Processing

Lubricants, which act as internal mold release agents, are commonly added to pultrusion resins to aid in processing of pultruded composites; however, the effects of these agents on the processing characteristics and final mechanical properties of the ...

8.  Enhanced Multi-Die, Multi-Stage, Pultrusion Technology

The potential market for pultrusion can be realized only by manufacturing high-volume and cost effective polymeric composites reliably, repetitively and profitably. Most components required for civil infrastructure (bridges), off-shore oil exploratio ...

9.  Improving Mold Release & Reducing Scumming In Closed Molding Operations

Certainly there has been a great deal more interest in the closed molding these days, due in part to the desire to reduce VOC’s, but also driven by the demand for greater productivity and better quality, and dimensional control of molded parts. ...

10.  A Solution for Composites Recycling Cement Process

This paper covers a newly developed process for waste composites recycling. Among many kinds of applications with composites, one of biggest problems in Japan, is how to treat and recycle waste FRP boats of pleasure boats and of fishing boats. Th ...
