PALSUN Technical Guide

PALSUNTechnical Manual2. Chemical Joints:PALSUN sheets can be joined to each other or to other materials by bonding or cementing, with or withoutprior preparation. Most such joints are suitable for relatively small to medium sized jobs. We present here afew possible options:Joint Design: The joint details should be thought over carefully, verifying that the bonding area spreads theintended loads equally, and the major stresses are either in tension or shear, so as to minimize separationand peel stresses.Lap Joints: They are most frequently used technique, in various designs, especially in relatively thin gaugeparts. The sheets’ edges overlap and are bonded together (in the suitable variation-fits for all sheet thicknesses).Some variations require routing or milling at the joints for proper execution.AFigure 22: Typical Lap JointsB,D,F, superior to A,C, E, / G,H corner lap jointsBCPALSUNPALSUNTapered simple lap jointDouble joggled Lap jointDouble butt lap jointDEFPALSUNPALSUNDouble Scraf Lap JointSingle lap / butt jointHDouble Lap / butt JointGPALSUNInterior corner lap jointBonding done by Solvent, Cement or AdhesivePALSUNAngled Exterior Lap JointAdhesive Tape BondingThin PALSUN PartsLap joints config.PressureTwo sides adhesive tape35
