Tests conducted by the US Naval Surface Warfare Center at Carderock, MD established that the properties of laminates produced by TPI's patented SCRIMP resin-infusion process are superior to low-energy pre-pregs used by many custom boat shops and twice the strength of hand lay-up. In our judgment, SCRIMP construction greatly reduces the chances of warranty claims due to laminate failures resulting over time from pounding into waves and/or rig tension or ballast loads.

The SCRIMP Process: The entire laminate, with longitudinal hull stringers and transverse keel floors, is placed in the mold dry. A high vacuum eliminates any air voids in the laminate then draws in only enough resin to "wet" the laminate. This is the TPI patented SCRIMP resin-infusion process. As can be seen from the chart above, SCRIMP laminate properties in terms of compression strength, flexure, and tension are twice the strength of hand lay-up and significantly stronger than low energy (vacuum bagged) post-cure pre-pregs. There is no entrained air in a SCRIMP laminate. 1% void content reduces flexural strength by 10%. Note that 50% fiber content in a carbon laminate equates to 67% carbon/33% resin by weight.
