1.  Newly Developed Spreadsheet Program Determines The Best & Lowest Cost Material/Design Combination For Composite Applications

The relationship between material properties, material price, part design, part performance and part cost is complex and often misunderstood. This is especially true for structural composite applications. For these applications the lowest priced mate ...

2.  Composite Structure Design to Distribute Concentrated Loads

It is well known that the mechanical characteristics of pultruded composite profiles allow interesting structural applications. However, the generally low elastic modulus as compared to traditional construction materials, particularly steel and alumi ...

3.  Computer Aided Engineering in Compression Molding

This paper focuses on how computer aided engineering (CAE) allows engineers at early stages of product design to predict and optimize mold filling, residual stress, structural response and post-processing shrinkage and warpage of the final part. The ...

4.  Computer Simulation of Resin Injection Pultrusion (RIP)

Pulling force modeling and analysis in conventional pultrusion and Resin Injection Pultrusiion (RIP) of vinylester resins were carried out in this study. A lab-scale pultrusion simulator was designed and built to measure the friction force between t ...

5.  Engineering Composites for Higher Crack Resistance

Cracking is perhaps one of the most common problems in today’s composites industry. Composites, like all materials, have their own unique performance shortcomings and drawbacks. Their reliability and durability has been well documented. Correct ...

6.  Simulation Of The Manufacturing Of An Ambulance Roof By Vacuum Assisted Resin Infusion (VARI)

In this paper, techniques to simulate resin infusion using classical RTM simulation software have been investigated. The difference in the filling behavior between “rigid” and “flexible” molds is evaluated and explained. Exp ...

7.  Improved Pull-Force Modeling in Injected Pultrusion

Injected pultrusion (IP) is a continuous process for manufacture of fiber-reinforced polymer composites. Measurement of the pull-force encountered in the pulling of the fibers through the injected pultrusion die is a commonly used indicator of the pr ...

8.  Ecologically and Economically Conscious Design of the Injected Pultrusion Process via Multi-objective Optimization

The current practice in injected pultrusion (IP) process design is based on expensive trial and error due to the absence of established processing models. Even for well-understood processes, chemical process design has traditionally used rigorous ste ...

9.  A Virtual Testing Methodology for Marine Composites to Develop Design Allowables

Preliminary design allowables for fiber-reinforced polymer (FRP) composite material mechanical properties are currently based on data found in the literature or from prior test programs. Mechanical property variability for nominally the same materia ...

10.  Analysis, Design, and Construction of a 40ft Composite Pedestrian Bridge.

Abstract The disadvantages of conventional materials, including the decreasing availability and rising cost of exotic wood products, coupled with advances in the cost-effective use of composite materials for bridge systems makes all-composite short t ...
