Forming Fiberglass Sheet

Here is how it works.

Forming fiberglass sheet.

This process involves utilizing a core material such as end grain balsa wood polyurethane foam vinyl foam or honeycomb between two laminate skins. Fiberglass is a lightweight yet very strong material that has many applications. The recommended radius of curvature should be a value greater than 180 times the thickness of the sheet for plexiglas g sheet and 300 times the thickness for plexiglas mc sheet see table below. A word of caution i use an electric heat gun and an infrared thermometer to monitor the temperatu.

Cold forming plexiglas sheet can be cold formed bent at room temperature in a smooth arc and held to a radius by forcing the material into a curved channel support. Add the hardener according to package instructions. 98 of products ordered ship from stock and deliver same or next day. Extra strength can be built into parts by means of sandwich core construction.

The first step is to cut a pattern from blue insulation foam and wrap it with clear packing tape. Fiberglass mat will require about twice as much resin as woven fiberglass for proper saturation. Now cover the pattern with woven fiberglass cloth and wet out the resin. It is found in cars and other vehicles as well as in some houses.

Make sure to leave a section uncovered this is where the foam will be melted. In our 45 years we have built tooling to produce over 12 000 different parts some simple but many challenging shapes as well. A large can or metal bowl will work but it should be of. Mcmaster carr is the complete source for your plant with over 595 000 products.

First build a smooth flat surface as large as the biggest panel you want. Precision metal forming shaping. As a fourth of july treat a tip on how to bend fiberglass. The resin is applied in multiple layers to increase strength and to attain desired thickness.

Next cover the taped pattern with a mold release wax. Measure an appropriate amount of resin in a metal container. If you apply pressure to fiberglass it will bend but its elastic nature means that once pressure is released the fiberglass will spring back to its original shape. Pacific metal stampings takes pride in our ability to form the most complex shapes using tooling produced in our own tool and die shop.

In a kit you will have a pre measured can or bucket of resin.
