By Rachael Idzior – GBI Composite Materials Engineer The technical department has been diligently working on an RV video series repairing a 28′ Shadow Cruiser travel trailer, with one repair focused on fixing a crack in the shower pan. Bonding to plastics can sometimes be a bit challenging, but with the right analysis, surface preparation, […]
by Rachael Geerts – GBI Composite Materials Engineer The 105 System is designed with a flexible, mix-and-match approach, like a chemistry set, allowing you to tailor formulations to your specific needs. Starting with the WEST SYSTEM® 105 Epoxy Resin® as a base, cure speed or clarity is determined by hardener selection, and viscosity can be […]
Core is a valuable part of composite construction. Core materials add stiffness while adding very little weight and usually low additional material costs. The construction of an I-beam is a perfect example of how increasing web height (or distance between two load-bearing flanges) increases the stiffness of a beam in cored composite laminates. Solid Laminate […]
By Rachael Geerts – GBI Composite Materials Engineer Have you ever wondered how laminate thickness can be determined without breaking out the epoxy and reinforcement fabric? The answer is simple—use math. While some of you may have just lost interest because you think math is too difficult, I can assure you that this math requires […]
Please Don’t By Rachael Geerts—GBI Composite Materials Engineer Every year we get questions regarding how to spray WEST SYSTEM® Epoxy. Some people want to know how to thin epoxy so it comes out of a spray gun better while others want to know what Personal Protective Equipment (PPE) is required for spraying epoxy safely. We […]
