SCRIMP Construction
What’s Unique About SCRIMP Construction?
Tests conducted by the US Naval Surface Warfare Center at Carderock, MD
established that the properties of laminates produced by
the
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.

SCRIMP Process The entire laminate is placed in the mold dry. A high vacuum
eliminates any air voids, then resin feed tubes draw in only enough resin to
"wet" the laminate. This is the 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. It only takes 1%
void content to reduce flexural strength by 10%! See the
comparison of composite properties of low cost fabrication methods in the
chart above.
Bonded Hull/Deck Joint
Extremely strong and watertight hull-to-deck joints are created by
chemically bonding the hull/deck flange overlap with 3M 5200 and Plexus
adhesive. This innovation, used on each new J/Boat since the
introduction of the J/105, yields a bond that is proven superior in strength
to a conventional bolted joint with 3M 5200, with less opportunity for
leaks, and less weight on deck. It is an ABS tested and
approved construction process.
Essential hardware elements along the deck edge are bolted through this
joint and sealed with Sikaflex bedding compound. Each flange (hull & deck)
is supported with extra glass laminates and designed to withstand high local
area stresses from stanchions, rails, & blocks. |
