Applying the wet-out fiberglass layers can be a messy experience. Sometimes these wetout layers are pre-cut and need to be applied in a specific orientation to fit properly. The following is part of the process used during the...
Read MoreComposite materials can become damaged in many different ways. There can also be flaws in the original manufacturing process. Many times it is necessary to identify any damaged areas within the composites layers that cannot be...
Read MoreRan across an interesting Youtube video demonstrating an epoxy resin infusion process on some test panels and fuselage. It is interesting how everybody has their own terminology and technique for resin infusion. There is...
Read MoreComposites structures have requirements for stiffness to provide support and stability. Tests can be completed to identify the stiffness of a given area on a composites structure, i.e. how much it will bend for a given force....
Read MoreVacuum bagging is a process that requires unique materials and processes, but can be simple to operation in an ongoing basis. There are many advantages to vacuum bag molding, a few of which include: Improved resin/glass ratio...
Read MoreA great Youtube video where testing was used to compare aluminum and fiberglass composite panels. This really helps to demonstrate the superior characteristics of the fiberglass. This video covers a quick resin infusion example,...
Read MoreOne of the challenges of using Gelcoat is the potential for the defect called alligatoring. This is described as a wrinkled surface on the completed part after it is removed from the mold, and results in extensive post-mold...
Read MoreMaking a traditional fiberglass part is accomplished by working from the outside surface into the part. A clean and waxed mold is placed in a clean room where contamination will not interfere. Then gelcoat is sprayed on as the...
Read MoreThe automotive aftermarket makes use of decorative carbon fiber as an aesthetic means to differentiate a vehicle. Carbon fiber hoods, spoilers, and interior pieces add a cool aspect to many of the “tuner” vehicles...
Read MoreI read an article on waterjet cutting of laminates recently, which demonstrated several advantages of using computer-controlled equipment for trimming and adding features to composites structures. Robotic-guided CNC routers have...
Read MoreVacuum Infusion and Vacuum Bagging can be accomplished are not only reserved for industry and can be accomplished in a workshop setting. Relatively inexpensively as well. One of the major variables is the shape of the part...
Read MoreThe thickness of the laminate will affect its stiffness. Stiffness can be increased by adding structural supports to the backside of the laminate, such as bulkheads and stringers in a boat. Another way to increase stiffness...
