Surface Pretreatment for Structural Bonding

It is regrettable that it has needed actual loss of life to secure that general acceptance and the necessary preventative measure [Pg.163]

Comment by Norman de Bmyne, founder of Aero Research Limited, on the Air Ministry s reluctance to make surface pre treatment of plywood mandatory prior to bonding. [Pg.163]

Abstract. This chapter is concerned with an in-depth examination of the adherend surface pretreatments used prior to structural adhesive bonding. It encompasses the various substrates encountered, particularly but not exclusively, in the aerospace industry. It compares and contrasts mechanical, chemical and electrochemical methods used for substrates comprising aluminium alloys, titanium, stainless steel, thermoplastic and thermoset fibre reinforced composites and non-metallic honeycomb. Scanning and transmission electron microscope techniques are used to analyse and characterise many of the pretreated surfaces so produced. [Pg.163]

Although the examples given below are specifically related to the aerospace industry, the techniques, in general, are valid for all industries using such substrates for structural adhesive bonding. [Pg.164]

This general principle is as true for wooden substrates as it is for the high tech carbon fibre laminates. Indeed, it was with the bonding of wood in aircraft structures that the requirement for surface pretreatment first came to light. [Pg.164]
